My Zvesda Fw-190 model

And so to the first of my three recent models of German aircraft. The Focke-Wulf Fw-190 A4 is one of the earlier models of this classic fighter aircraft. The 190A is one of my favourite WW2 planes from an aesthetic point of view, up there with the Mosquito and Spitfire Mk VIII/IX.

I wanted to model one of the early variants, which were around in early 1943, in one of the Mediterranean camouflage schemes. These early planes were slightly shorter than the later ones (from the A5 on, and the F series of fighter-bombers), which had the engine pushed slightly forwards to shift the centre of gravity, to ease the carrying of bombs. To meet my aim meant going for one of the pure fighter planes in JG2. Some early fighter-bombers were deployed in Tunisia at this time, but they seem to have used the standard European grey colour scheme. This would have made them look very like the A5 fighter-bomber that I plan to make later on. Given this, the Zvesda kit pretty much chose itself. Most models, like the Airfix one, of the 190A are of the later A8, which belongs to 1944. And I wanted a simpler, cheaper model at this stage in my modelling journey.

The Zvesda kit was an excellent choice. It has an undercarriage-up option, and comes with a pilot. Better than that, the fit of the parts is excellent; it needed very little filler. How unlike the kits of my youth! And also better than the low-cost Hobby Boss models. It sells as a snap fit model, without the need for glue. I did use glue, but it was only actually needed it in one or two places. I have just one significant complaint – the Fw-190’s tail wheel partly retracts in flight – but on the model it is in the fully down position. It was a bit tricky to replicate the retracted version. The decals aren’t great either. The only other point to note is that there are no bomb racks included with this kit to make a fighter-bomber version (which would also require the removal of the outer wing cannon) – though not many of these entered service for the A4. Sometimes kits are supplied with extra parts to make different versions, even ones for which instructions and decals are not supplied – not this one. Based on this kit though, Zvesda are the ideal maker of 1/72 kits for wargames purposes. The shame is that they only have a limited range of models. It looks OK for Russian aircraft (unsurprisingly), but otherwise it’s thin. There is no later, or fighter-bomber, version of the Fw-190 – a bit strange given how big a role this aircraft played on the Russian front. But there are a couple of Bf 109s, and they might be a better source for these than the Airfix or Hobby Boss kits that I have bought.

II Group of JG2 (Staffels 4, 5 and 6) was sent to Tunisia in November 1942 as part of a general rush of German reinforcements to this theatre – the unit had been based on the English Channel (the aircraft in the Imperial War Museum that landed in England in 1942 by accident was from JG2). They stayed until February 1943, and were the only Fw-190 fighters to be deployed in the Mediterranean in the war, as opposed to fighter-bombers. Only 109s took up the fighter role for the rest of the war, in a demonstration of the economic principle of comparative advantage – the Fw-190 was generally thought to be a superior fighter to the 109, but the latter was a much inferior fighter-bomber. What colour scheme? The Luftwaffe Mediterranean schemes were always ad-hoc, and that applies even more to Tunisia; there was no manual. Tunisia itself in winter was quite green for the most part, meaning that many of the aircraft rushed in were not given a new paint job at all, like the Fw-190 fighter-bombers. However there is evidence that at least some of JG2’s were. Unfortunately there are very few photos, and even fewer of them are available on online searches, so I’m relying mainly on secondary interpretations. The kit comes with decals for White 14 from 5 Staffel in Tunisia. This appears to simply have blobs of overpainting on the conventional grey scheme (and with the white on the fuselage Balkenkreuz painted out). This wasn’t very interesting. Two other schemes come up in searches: a group staff plane (with black chevrons) in overall sand upper parts, and Yellow 1 from 6 Staffel, either shown in just sand, or in sand with broad olive green stripes. Yellow 1 (1 denoting staffel leader) was flown by fighter ace Erich Rudorffer. I wanted the sand and green scheme, which would give me practice for the similar British schemes (sand and brown stripes), but I didn’t want a famous ace, but something more generic. I decided to do one from the same staffel but with a different number (seven in the end) – fictional, perhaps, but the sort of generic thing suitable for the tabletop. Details on Yellow 1 vary on the illustrations. Sometimes it is shown with white wing stripes – markings which were apparently used by German planes in Vichy France, but these would not have appeared on planes in Tunisia. Also shown are white underwing tips, yellow under the engine cowling and a yellow rudder (as well as the white fuselage stripe which almost all Axis planes in the theatre had). All of these appear on German fighters in the theatre, but not universally. The yellow markings were also used by JG2 planes in their previous posting on the Channel. My speculation is that the upper parts of the planes were overpainted in sand and olive green, but the underparts were left in the pale blue-grey of the original scheme (rather than azure in the German Mediterranean set). Winter in Tunisia wasn’t particularly sunny (it rained a lot), so there was no good reason to overpaint the underside. Besides a large part of the use of aircraft camouflage schemes in this theatre was to make the planes less conspicuous on the ground, as the airfields were quite basic, and there was little cover. Even the Americans were forced to do this in 1944 when they stopped painting their aircraft at the factories. So, I reasoned, they would have overpainted the yellow rudder but left the yellow under the cowling. I wasn’t sure about the white wingtips, but these aren’t very conspicuous, so I left them out.

Here’s the finished model:

And underneath:

There’s not much to note on the build. It was very straightforward apart from the tail wheel. I used the airbrush to prime, but this time with LifeColor purpose made white primer. This went on more easily than standard paint, but there was still a slight tendency to bubble (even though the parts had been washed). The sand and olive green were mixed for use on this and the other models – the sand on all three models, and the green with the 109. The pale blue grey (“white-blue”) was mixed just for this model. I took the darker light blue I used for the Stuka and mixed some white into it. It should probably have been a bit greyer (on the Stuka too). The sand was Raw Siena with a bit of blue and white – and I am very happy with how that turned out. It’s a bit darker than it is often shown, but close to many representations of this aircraft. The olive green is usually shown as been noticeably darker than the sand (which comes out on may photos) but in this case I thought it would be tonally similar. One the one photo I have of Yellow 1 (showing just the nose) the stripes are nearly invisible. I started with Sap Green, mixed in some Yellow Oxide and white. That works well on this model.

I have already written of my traumas at the painting stage. I painted the whole upper surface in sand, and then over sprayed the green on top, using Science Putty for masking. I used this product as an alternative to the more expensive “Panzer Putty”, and it worked pretty well. However the problem with it is that it moves, so you can’t leave it on the model for long. Blue Tac is probably more appropriate. I had to top up a lot of the airbrushed green with a paintbrush. For the decals I used the Balkankreuz that came with the model for the fuselage and underwing, but they supplied the simplified cross for the overwing, which didn’t seem to be accurate. At this stage, and in this theatre, the Germans seemed to use the standard cross with a thinner white band. This, and ID markings and the swastika were all sourced from my brother’s stock of German markings from the 1970s (or even late 1960s), mainly from Almark. Almark still seem to be going, though Scalemates says they started in 1975, my brother’s main modelling activity in 1/72 was long before this, and I generally only needed the swastikas for my models at this time, so I don’t think I bought these. Zvesda do supply swastikas, but, doubtless for legal reasons, they are cut in pieces and a faff to put on. The old decals took a little while to free themselves from the backing paper, but then were fine to manipulate – actually easier than many of the modern ones. Using decal fluid the flash, a big problem back in the day, disappears – though it didn’t help that we usually applied them to matt enamel painted surfaces. For the ID markings I had to put on the yellow markings first, and then the black outlines over them. I am very pleased with how they turned out.

Overall I am very pleased with the result on the upper surfaces, in spite of the nightmare on the oil paint patination. The LifeColor matt varnish has left a faint sheen (or maybe it’s the oil coming through) which is just what I wanted. While American planes in the Olive drab scheme often appear in a very matt finish, this seems less true of Luftwaffe planes. Doubtless the crews kept the planes clean to extract every ounce of aerodynamic performance. The whole effect is cleaner than the P-47, but consistent with a recently-painted aircraft. The patination nevertheless helps to integrate the whole model, including decals, and give it more of a real-world feel. The underside is much less satisfactory. The main problem is that it is too monotonous. Some of the detail could have done with being brought out. The fit of the undercarriage doors is so good you can hardly see them! The patination effect is also much more visible and makes it look a bit mucky. That’s not unrealistic in itself, remembering that this is the bit that wasn’t overpainted, and the underside would have taken a pounding from dust on take-off and landing, but it still doesn’t look quite right. But after the traumas with the oil, I wanted to draw a line under the project, and had no wish to spend yet more time trying to fix it. The underside is not going to be that visible on the table after all.

Wargames bases for 1-72 aircraft

My P-47 soars high above my workbench on the newly made stand.

After the first WW2 aircraft for my wargames collection, the P-47 Thunderbolt, I decided that I needed to have flight stands ready before I attempted my next set of models, and to build in the mounting from the start. This would have the advantage of having somewhere to put models while paint was drying, etc. I had hoped to be able to buy something that could be used straightaway. The closest I could find came from Debris of War, which was really meant for smaller scales. This was very neat, but I thought it really wouldn’t work for larger models, just as they said; apart from anything else it doesn’t extend that high. I would have to make my own. This turned out to be not especially hard. In this post I will explain how I did it. There are a couple of things I learnt on the way, so this may help anybody who wants to do something similar.

The starting point is a magnetic, extendable pickup tool. There are quite a few on the market. I tried out two different sorts. The obvious choice was the Amtech 2255 which can be had for a mere £2.59 on Amazon. Worried that this was too good to be true, I also bought another one from Raguso, which sells at £5.89 on Amazon. The Amtech is bulkier and extends a few centimetres less than the Raguso; the magnet at the end has a wider diameter, which is probably better for my purposes. But both work fine. The magnets are quite powerful, making the attachment pretty secure for models assembled from plastic kits. The Amtech is cheaper and delivery from Amazon is much quicker; there really is no reason not to go for this one, so I bought a few of them.

Both have basically the same structure: a telescopic arm (like an aerial) with a magnet fixed at one end, and with a pocket clip at the other end secured with a screw-in top. This is the Amtech one dis-assembled:

The clip serves no function for us, but the removable top comes in handy. This is bigger and domed on the Amtech; the Raguso one is neater and flatter. Next we need a base. I cut this from hardboard, simply because I had some lying around that needed to be used up. This material works, but is not so good for drilling holes in, as I found out later. MDF or hard plastic/acetate would probably be more appropriate. I cut out four inch squares. I thought this would give the best balance between stability and footprint. Something slightly smaller might well be just as good if I you weight it down properly. It doesn’t need to be bigger. I used the square shape because I wasn’t up for cutting out a circle, and I quite like squares on the games table anyway. I think you can get pre-cut circles of MDF or acetate quite easily.

So how to fix the arm to the base? My first idea was to glue the screw-in top into a recess drilled into the base, and then screw the arm onto that. However, the need to make sure the arm was properly vertical meant that in practice I needed to glue the whole assembly in. Then there was the question of adhesive. Having read that people used “liquid nails” I tried Unibond No More Nails. This failed. The adhesive didn’t bond particularly strongly in the context, and in a any case simply trying to glue the arm to the base was asking for trouble, given the leverage on the arm and the sort of forces that the joint was going to have to withstand. Take two. This time I drilled a hole right through the base. Hardboard has a bit of give, meaning that the it bulged a bit on the exit side of the hole, which had to be tidied up with a knife. I then glued a 2cm mudguard washer over the hole. I found some ancient Araldite in my things and I used this, having lost faith in No More Nails. Here is the result, with the Amtech device. Because the drilled hole was slightly bigger than the diameter of the top, I widened it a bit at the top and glued the washer in with it in place. This wasn’t necessary with the Raguso device.

The arm was then simply screwed onto the washer with the top, to create a very satisfactory fixing. This is the Raguso one.

Next I felt the need to add extra weight to the base to ensure it was properly stable, especially with the arm extended. For this I used a collection of old coins I had from my 20th Century travels, including a lot of pre-Euro ones. I sifted out the ones that were attracted to a magnet, as I though these might have other uses. Other alternatives might include washers or similar bits of hardware, which can be had very cheaply from specialist suppliers like RS. One blog I read used a small number of very large washers for this, and that looks a good way to go. I used the No More Nails to glue them on. This shows one of each type of arm;

Next the coins were covered with plaster, mixed with paint (brown, yellow and white tempera), together with some of my old mode railway ballast to give it texture. The ballast didn’t work; some sand would have been much bette, but I didn’t have any cheap stuff to hand:

This is all standard terrain making stuff. I simply added flock next. I used two sorts of Woodlands scenic flock, plus some Games Workshop sand (ridiculously expensive but quite nice looking – I only use it for decoration). This was to get the arid terrain look. What worked best to semi mix the three components, and put it all onto the wet PVA at once – rather than applying the different types separately. I then sprayed more PVA onto it to seal it. Finally I painted the edges with a mix of Raw Umber and white to tidy it up. Of course you can be much more ambitious, with bits of scrub, rocks, etc. But I was in a hurry and I didn’t want the bases to draw attention to themselves. Anyway here is the end result:

All very easy. Of course at various stages things had to be left to dry out, so it took a few days altogether, but this could be fitted in alongside my other projects.

How about the mounting on the model? This is a bit of a work in progress. I started with a simple small steel screw – having drilled a hole into the model with a gimlet. This was robust but not entirely stable (though the model would not have been in danger). I then used the screw to attach a steel mudguard washer, which you can see from the picture above. This wasn’t completely horizontal (because it needed to follow the line of the model’s belly), and the screw wasn’t entirely flush. It nevertheless turned out to be very functional. The attachment is very stable and the slightly raised screw head allows for subtly different flight angles to be made. But it is over the top and unsightly. I’m thinking of gluing on a small coin if an appropriately angled surface is available. Hiding something with iron inside the model might work in some cases. it is a work in progresss.

Incidentally something I have discovered the hard way is that not all steel is attracted to magnets. Some stainless steel isn’t. When buying online it is safest to avoid stainless steel. I bought some the screw and washer from RS Online, though absurdly more than I will need to mount aircraft models: here are the screws and the mudguard washers; they both work with magnets. These are same size as the washers I used to fix the base, but in fact I used some I had bought a couple of years ago for basing 20mm infantry, that I thought would attach to magnets but don’t. Lesson learned.

UPDATE 16 March. I have found that the RS 12mm screws above are quite sufficient of themselves to fix to the model, without the need for anything bigger like a washer or small coin. This is for a Bf 109 and an FW 190, which are quite small, and also for a Stuka, which is a bit bigger. I drilled a hole into the underside with a model drill, enlarged it a little with a gimlet, and then fixed the screw in gently with a screwdriver; in all cases this was into a single kit part, not a join. Getting the angle exactly right is a bit tricky. In two cases I managed to get the head in a millimetre or two off flush; in the other (FW 190) another millimetre or two off – I was unwilling to force the screwdriver in case the force broke the model. The attachment is vey secure.

Olive drab

Readers familiar with my blogs may have noticed an omission from previous post on the P-47. I didn’t say anything about the paint colours. And I’m usually a bit obsessive about that. A lot of hobbyists are, but I take it in an unusual direction because I mix my own paints from artists’ pigments, separately for each project. I left the topic out because I had too much to say. It needed another post, which readers less obsessed with colours can skip, and this is it.

The predominant colour on this model is, of course, Olive Drab. The underside colour is Neutral Grey, a mix of black and white, the main question around which is how light it should be. I based my colour on an old artists’ Liquitex Neutral Grey I had lying around; if it hadn’t been there I would have mixed Mars Black and Titanium White. The Liquitex colour is probably 50:50 and turned out to be a bit dark, so I added some white to it. From photos I suspect that the USAAF grey is a bit darker than it is portrayed by most artists, as the tonal contrast between it and Olive Drab isn’t that great. But I went quite pale nevertheless; white with everything is my standard practice for miniatures painting after all. Other colours are yellow for the stripes and red for the nose. My main concern with these was to make them bright but not too bright. For the red I recycled some red from my previous project (French Napoleonic cavalry) that was still wet on the palette, though I found myself tweaking it a bit. Yellow is a bit of problem because pigments tend to be bodiless and thin. I like to use Yellow Ochre or Yellow Oxide (the Liquitex name, but much the same thing), as this is the best behaved, but it is a bit dull, do I used some of my other yellow pigments. First an old yellow (can’t remember the name, but its not on sale any more) that was horrid and thin, and then Cadmium Yellow that was better. A little white was in there of course. But the result was still thin. I painted the stripes (with a brush over masking tape) over the Olive Drab and Neutral Grey, which had been airbrushed on. I started with an undercoat of white, but it still took at least three coats of the yellow mix to get anything satisfactory. Maybe next time (the yellow stripes will probably feature on my A-36 too) I will paint them first and mask before airbrushing the main colours.

But the big interest is the Olive Drab. This was the standard US military colour, developed in WW1 and used on both vehicles and aircraft in WW2. It is a notoriously tricky colour to pin down. The US authorities were very pragmatic on colour standards, and did not care greatly whether the colour precisely matched the standard, and it weathered quite dramatically. The official formulation changed slightly from time to time, and eventually the Army and USAAF went for slightly different definitions. Different companies used different pigment combinations (and doubtless changed these over time), so even the weathering varied a great deal. The colour could vary a great deal across the same aircraft, depending on when that particular part was painted. Probably no two vehicles or planes were the same colour (apparently like modern Israeli tanks), because in wartime this just didn’t matter. This causes hobbyists – wargamers, modellers, collectors or re-enactors – a lot of angst. Modellers like their premixed paints, and often ask which one to use, to which the answer has to be a shrug; “several” is to them the wrong answer. Collectors either paint with something like the as-new shade (doubtless in a modern paint that is much more colour-fast than the old ones) or make up a lighter shade to simulate what they think it might have looked like in the field, but which tends to look too fresh and new.

Meanwhile we have not so much evidence for what planes and vehicles actually looked like. Colour photography wasn’t prevalent, and not especially accurate on colour either; colourised photos, increasingly popular, are just an interpretation. And as with all dull colours in the middle of the colour wheel, small differences to colour sensitivity and lighting can make a big difference to how it looks to the human eye. This website (gmodelart.com) has a number of interesting pictures of aircraft, though (leading with one of a crashed P-47 in very similar scheme to my model), which shows how much variation there might be, even on the same plane.

So what colour is it? “Pig crap” is an early description of the dark, freshly painted version. Olive is just on the green side of yellow on the colour wheel, but the “drab” takes it a long way towards the middle, meaning that it is quite brown. To date I have tried simulating it with a mix of three pigments: Yellow Oxide (i.e. Yellow Ochre), Black and White. I have assumed the standard way of making it was combining yellow ochre with black, as these were two cheap pigments – just as the French did in the Napoleonic wars to make the olive green they used for artillery woodwork. Here is a picture of the sorts of result yI get:

On the left you have just black and yellow; this is as close as I could get in tone to the colour swatch I have, which show the colour as new. In fact the swatches were slightly greener – but more yellow would have made it a bit too light I though. Fresh Olive Drab is a very dark colour, something that caused me consternation when I applied authentic Humbrols too my models back in the day. Next has a bit of white and a bit more yellow (I was assuming that the black would fade faster than the yellow); it turns into something a bit greener. On the right I have mixed the yellow with Neutral Grey to give something lighter and browner. My model is painted in something between the right hand and centre pictures. If nothing else this exercise shows how challenging photography is in representing colour; they all look darker than they “really” are.

As another exercise in demonstrating the perils of photography: the following show the effects of different backgrounds. The red in particular makes the model look browner, while the green makes it look greener. I don’t really understand that!. The lighting conditions were slightly different for this photo than the other three though.

Comparing these photos with the ones on gmodelart.com and my model is in the right zone, but looks a bit dark; it seems closest to the new Liberator bombers. But all the photos were taken in bright sunlight while I took my pictures on an overcast day, with a little artificial light to boost it a bit (and a lot more artificial light for the one against green cloth).

A further thought is that my idea that Olive Drab was often made using yellow ochre and black is probably off the mark. These may have been the appropriate pigments in the pre-industrial age, or even in Europe, where green pigments were in short supply, but 1940s America is another matter. The original formulation of the colour included raw umber, a dark brown. Chrome yellow was a standard primer, used in the interior of aircraft – this is brighter and greener than ochre. The greener hue of the colour swatches suggests it wasn’t ochre-black. It might be worth trying a different formulation, to produce something with a slightly greener hue. On the other hand the black-ochre combination produces a nice, opaque paint that is very easy to apply. A brief attempt to produce something using Raw Umber and Viridian was not nearly as good.

So where next? The issue will return when I do my batch of three US planes. The main issue is not the precise hue, but that fact that the colour is not standard. There should be a bit of variation between the planes and on the same aircraft. It is less of an issue for vehicles, since in 1943 most US vehicles used by the British were repainted. But if I move out into later war or US forces (and I’m thinking of just that in 1/300), the issue will return. This is a problem that will run and run.

My aero modelling journey begins: Hobby Boss P-47 Thunderbolt

My lockdown madness has drawn my into 1/72 model aircraft. This is nominally part of my 1943 wargames project – but mainly a rekindling of my love of warplanes, especially from WW2. Somehow, and only my fellow hobbyists will understand how this has happened, I have acquired no less than 14 kits to make. My plan was to build them in batches of three, or even four, starting with the three US planes (an A-36 Apache, a P-38 Lightning and a B-26 Marauder) because their simpler colour scheme would be a good place to start. I then realised that aircraft modelling involved so many new techniques that it was best to start out n a single low-cost model that I didn’t mind mucking up. So I bought the Hobby Boss P-47 Thunderbolt. I have just finished it (more or less).

This aircraft does not belong in the scope of my 1943 project. The first P-47s were deployed in 1943, but these were of the ridgeback variety. There was only limited availability of cheap kits though – the three makes that seemed to be in scope were Airfix, Zvesda and Hobby Boss. I was looking for a US aircraft. The only available Airfix model was an early P-40, well before my period. Hobby Boss did the P-47, but only the bubble-top variety was available at short notice (they have done a razorback as well). I have a soft spot for the Jug, since a made a model an old Airfix one (a ridgeback as it happens, with moulded raised rivets – yuck) as a boy, which I didn’t even paint. The bubble-tops weren’t operational until well into 1944 – but they are handsome aircraft.

Hobby Boss models are simple and cheap, with only a small number of parts. But there was a big snag. They follow the modern convention of making planes with undercarriage down and no pilot. This is how all upmarket aircraft kits are presented these days – but you would have thought cheaper models would appeal to youngsters and wargamers, who would like to make them up as in flight. The box artwork shows the plane in flight – and it even appears to be a photo of the model. Airfix and Zvesda both give this option. The Hobby Boss had the tail wheel door moulded open. And the P-47 main undercarriage doors were in three parts, with the upper two moving to overlapping position when downed; these are moulded as a single piece in the kit, which had to be separated. All this involved some pretty tricky conversion work to model as retracted. The main doors did not fit into the holes exactly and had to be filed down. And fitting them flush was more than tricky, until (on the last door to be fitted) I discovered the use of plasticine. The tail doors I gave up entirely on. I just filled in the hole and filed it flush, and tried to score some doors in. The results of all this were very far from satisfactory, especially the tail door. I won’t have another set of tail doors to model until the Spitfire VIII, though, which I plan to do last, and which has properly moulded separate doors in the model. But modelling the doors as closed for the main undercarriage is going to be tricky for the one further Hobby Boss model (a Bf-109), and the seven “up-market” models I have now acquired. At least these usually have upper and lower wings in separate parts (Hobby Boss has the wings in a sing piece), making the doors much easier to fit flush.

Apart from this major problem, the Hobby Boss model fitted the brief perfectly. The interior detail of the cockpit is poor; the bombs are crude and inaccurate; not fitting the central fuel tank leaves an unsightly hole in the bottom centre of the fuselage; the panel lines are very shallow; the engine detail is derisory. But none of this really matters for the sort of model I was trying to make. You can’t really see into the cockpit; the bombs aren’t particularly visible; the fuel tank hole is where the flight stand attachment will go; overdoing the panel lines would be a worse error; and you have to look closely to see into the engine. What I got was a simple and robust model, much like my PSC tanks and APCs.

There was a problem with the decals though. By the time the bubble-top came into operation, US aircraft were no longer being painted at the factory, and almost all of them flew in bare metal. Both decal schemes were for such bare-metal aircraft. This is not a problem for the star and stripe insignia, but it is for the lettering, which is black on bare-metal aircraft, and yellow or white on painted ones. In the Mediterranean, however, aircraft were often left out in the open when on the ground, so many aircraft were painted by the service crews to make them less visible, using traditional olive drab and neutral grey. I found an example of such an aircraft in the Eduard “Jugs over Italy” kit (in 1/48), with the schemes and made models readily visible on the Internet. My scheme is based on this but with made-up serial number (the smaller yellow figures on the tail) and battle number (large white ones on the fuselage). I had an audacious plan to solve this, I actually had the unused decals from my old Airfix P-47 kit, getting on for 50 years old, which included a scheme for for a painted plane. Unfortunately these were damaged, and broke up when I tried to use them. My next solution was to try and cut out a 1 and 7 from the white decal printing sheet for the battle numbers. But these proved much too delicate. Apparently for decal paper to work this need to have a hefty layer of varnish on them. For the battle numbers my next plan was to overpaint some of the black numbers that came with the kit, of which the simplest was a “41” (actually converted from “4P”). This was hard going, and it was impossible to get either properly straight edges or an even paint coverage. To my surprise it worked. The imperfections are much less noticeable on the weather-beaten look I was going for. It looked as if the ground crew didn’t have the stencils or spray gun when they had to apply the numbers; I expect such things happened. For the serials wanted to print some numbers on transparent decal paper; I was bit concerned because my last attempt at this turned out to be rather transparent; standard printer ink doesn’t have a great deal of body. In fact my inkjet printer heads were completely messed up and unable to print much colour at all. but I found some old British Railway locomotive decals from a model one of my brothers must have bought, which would have been even older than my P-47. They were the right size and colour, but in Gill Sans script rather than USAAF stencils. Actually from a distance these aren’t too dissimilar, except for the zero, which is a big round “O” in Gill Sans. This featured in the numbers, but I cut the zeros out, and assembled the numbers from three pairs each. Apart from taking quite a while to loosen up from the backing paper, these decals worked fine. They evidently aged much better than my old P-47 ones. Finally on the engine cowl I simply used nose art from the Hobby boss decals, one for the plane “rabbit” and the other presumably for the unit. This was all part of the P-47 look.

There were two really scary things about this project for me. The first was use of the airbrush for the first time, and the second was weathering. The first issue was primer. I had bought some artists’ gesso to use for primer, but I found this didn’t bond well to plastic (though works fine on metal). Instead I used standard white acrylic paint that came with the airbrush. Initially this didn’t bond all that well either (even though I had washed the kit first), but with a bit of help from a paintbrush I got started. That first session with the airbrush was a bit nightmarish. I kept on getting it wrong, with the paint pooling up, which I then had to thin out with a paintbrush. After the white I tried putting on a layer of neutral grey (over the whole model, though only needed for the underside), but I ended the session with the model looking a real mess. Next session, after watching a couple of videos on airbrushing models, it went much better. And each time since my confidence has improved. A number of factors have to be balanced (air pressure, thickness of paint, openness of nozzle and distance from subject), and this clearly takes a while to come together. The big surprise to me is just how thin the paint is when it goes on properly. This is quite unlike an aerosol can. The flip side to this is that the spray is pretty controllable, and paint doesn’t go everywhere, like the aerosol. This thinness is what gives airbrushed paint such a lovely finish, of course. But it does mean the layers shine through each other. Using a white undercoat made a big difference. In one place (the lower rudder) I used a brush to correct an error: it came out much darker. Underpainting in dark colours to bring out individual panels is quite the fashion for serious aircraft modellers. I did try this with black for the undercarriage doors, but not very successfully (the underpainting needed to graded). One aspect of the thinness I hadn’t counted on is that the paint is very easy to damage. I quite often chipped paint off right down the plastic. This may suggest that a proper primer is advisable, and I have bought some from the airbrush company for future projects. But it also explains why modellers seem to be so keen on layers of varnish.

After the basic paint job I applied the decals. As with my vehicle models I applied to a layer of polyurethane gloss varnish (from a very old Humbrol pot), put on with a brush. I forgot to do this on the tail, though, but the decals (and these were the very old ones) went on fine with the help of decal fluid, with no flash showing. The smoothness of the airbrush finish probably means that this step is superfluous – except that it is an excuse to put on a layer of protective varnish. The decal application didn’t go that well, as I managed to spill almost a whole bottle of decal fluid. As a result of being a bit stressed by this, some of the decals were damaged and there was a little (and unforgivable) creasing. After this I wondered whether I could go straight on to the weathering without sealing the decals in varnish, as the finish looked quite good. But by then I was starting to understand that layers of varnish were a good thing. At that point though the only airbushable varnish I has was matt – and that was a bad idea at this stage. Decals are allergic to modern matt varnish; back in the day matt varnish was really satin, and I used it to set the decals (with the glue washed off the back) as a way of eliminating flash – a job the decal fluid now seems to do. I had some old Humbrol satin varnish, and I used this with a paint brush. This produced a very good finish on the top, but it has a slight orange colour to it, which discoloured the underside where it was a bit thicker. It also filled in some of the engraved lines, making them impossible to bring out in a wash. Unlike proper aeromodellers, I’m not that fussed about bringing out the panels – but I do like to show up the moving parts, like the control surfaces and the flaps on the engine cowling (which are completely lost on this model now). I now have airbrushable colourless gloss varnish. My idea is to use this before and after decals, with a wash to bring out the engraving before either or both coats.

Weathering is a multi-stage process for serious modellers (more than a dozen steps on one blog). I was looking for something much simpler. My plan was to use two main techniques: the “dot filter” method, applying oil paint, and pastel dust. I also did a little “chipping”, as well as a largely unsuccessful wash. The dot filter requires quite a bit of courage. You put small dots of oil paint of different colours on the surface, and then keep brushing into a very thin layer with subtle variations that bring out the direction of the brush strokes (generally fore-and aft to simulate the effect of air flow). Oil paint dries slowly, so you have time to brush it down very thin (and you can also clean it off with white spirit and tissue). The paint I used was white, Payne’s Grey, Raw Sienna and a little bit of Van Dyck Brown (being very sparing with the browns on the underside). I had bought these colours to paint horses, so the choice was a bit constrained (Yellow Ochre and Raw Umber would be good choices ordinarily). I did it after decals, rather than before (as advised by the blog I was following), because I wanted to integrate the decals into the overall finish. When I first pulled the brush over the spots, it looked like a disaster (it helps to see a video of this first to prepare you for the shock), but eventually the paint spread so thin that the effect was very pleasing. The red band on the nose was the only real problem; it did not respond well to the white, and so I had to use a bit of white spirit to thin it. The overall effect is to patinate the model and soften the paintwork and decals (the white is especially effective). There should be elements of unevenness too, to reflect where the different coloured spots went. It all helps to bring life to the model.

The use of artists’ pastels was an idea I got from another blog, as a substitute for weathering powders that are popular with modellers. I actually have a decent stock of pastels, which I had bought for use on terrain (not particularly successfully so far). You scrape off some powder with a craft knife and apply with a paint brush. At first I tried it directly after the oil patina had been applied. The oil immediately dissolved the powder, turning it into a liquid smear. This is potentially quite useful, but not the effect I was looking for, so I waited for a day for the oil paint to dry. I can’t say that I have mastered this technique. I tried to use it to provide a bit of contrast on the control surfaces, where the engraving couldn’t be brought out with a wash. In particular the ailerons merged with the flaps (though at least both were delineated from the wing). This wasn’t very successful; in fact it would have been better to try this while the oil was still wet, as the dry powder doesn’t do sharp edges. I was more successful in applying dark smudges to suggest exhaust stains by the engine cowling, and areas of dirt on the wing to suggest mud from ground crew boots, etc.

I also used a little silver paint to suggest places where the paintwork had been chipped back to the metal. Some modellers go to town on this, but I’m not sure how realistic this is. Japanese aircraft were notorious for paintwork being in terrible condition, but not other nations. The artist in the Osprey publication on B-26s in the Med delights in showing these planes with paintwork being in a very poor way, though I don’t think this is clear from the photos. But these bombers were exposed to airburst shells from heavy AA in the way fighter planes weren’t. The popular way for modellers to do this is using silver artist’s pencil, but I was reluctant to splash out. You can see my efforts the wing route in the picture. there are one or two spots elsewhere. I don’t think I have this quite right yet, but I’m not sure what is wrong.

The final step was a layer of matt varnish. I have lots of this in aerosol cans (a long story…), and I wasn’t bothered about it being quite heavy-handed, so I used this rather than airbrush. I wasn’t sure about this step. After the satin varnish, and the oil patina, with contrasting matt pastel I thought the model looked pretty decent as was. Aero modellers insist that a high matt look is authentic for this era, and in the Med, with all its dust and outdoors exposure, this makes more sense than elsewhere. But high matt isn’t great for aerodynamics, so I thought planes were quite often polished to a satin type finish – and this is how I used to present my models, using the satin “matt” varnish. Still this model is a learning experience, so I thought I had better try it. I think it does work, and it does recall contemporary photos of combat planes in this era, especially the US olive drab planes.The propellor was left off the for this phase, though, and I gave it a coat of satin varnish.

This model isn’t quite finished. First is the canopy. I attached it before the airbrushing, as I wanted to cover the joins for the static part in modelling putty. I used masking tape to cover the transparent bits, leaving the frame exposed to the airbrush. The masking tape came off after the matt varnish. The result on the canopy from was OK-ish after a bit of touching up, but the tape left marks on the canopy. Unfortunately the polish I had specially acquired to clean the canopy up has gone walkabout, so I’m waiting for it to re-emerge. Second the plane needs a stand. This has been a been a bit of a problem. Commercial stands are for much smaller models. For larger ones it is popular to make your own, either using an acetate stick or an extendable metal aerial. In the end I bought one made for an extendable aerial from Debris of War – but with a 3in base it is meant for smaller models (15mm scale single-engined aircraft max). I hope to be able to modify it to work for larger models, up to my planned B-26. A magnet is attached o the model to attach it to the stand. It would be a good idea to integrate this with the model building process, rather than it being an afterthought, as it would be useful to have somewhere to leave the model while paint is drying, etc. The stand is in the post.

Overall the model comes up to an acceptable wargames standard, and meets my needs. The underside is a bit of a mess, partly because of the botching of the undercarriage doors, and partly because the varnish was a bit thick and discoloured it. The weathering is a bit heavy-handed too, but that’s less of a issue – it doesn’t look implausible. Actually I’m very pleased with how this model has turned out. There may be a bit of a fine line between a model looking botched (I had lots of those in my youth), and one that looks realistically weathered, but on the topside at least, the model is on the right side of the line.

I have greatly enjoyed my return to aero modelling, even if it is a bit of a distraction from other hobby projects. It has given me a fresh understanding about how close hobby projects are to art, and how much they can be informed by art (I leave to one side whether the hobby actually is art). I am no artist, but I do take a close interest in art. What I have learnt from art is how to understand and deal with the series of subjective choices that any form of representation presents. You need to develop a clear idea of what it is you are trying to do. Serious aero-modellers want to present you with model you feel you can jump into and fly away in. The model needs to be coherent, but they like to overwhelm the viewer with tiny details to give you that feeling that you can are in the presence of a real plane. 1/72 o is a bit small for this (I can see the attraction of 1/48; I did make a couple of 1/32 models in my time, and they’re too big). I think they overdo things sometimes though, especially an obsession with panels. My aim is much more impressionistic. I want to convey an impression of a plane in action with a job to do; viewing is typically meant to be at a greater distance – and I do want to convey the idea of a purposeful and menacing machine. This allows me to adopt a much simpler approach and still produce something with its own impact. The weathering step is particularly interesting here; apart from serving to give the model a used appearance, reminiscent of wartime photographs, it helps unify the model, for example by integrating the decals and ID stripes. It may also help to show up moving parts, conveying that this is a working machine – though no so much on my model.

It was certainly right to get started on a single model. Some key learnings are as follows:

  • The airbrush produces a beautiful finish, and is ideal for this type of model, allowing the fine detail of the mouldings to come out. This is quite different from painting much hunkier metal miniatures. But the paint finish is quite delicate, and it can be a bit too smooth, requiring the weathering phase to bring the model to life.
  • The workflow is very different from painting miniatures with an ordinary, or even the vehicle models that I have done to date. There aremore gaps between steps to wait for things to dry out – leading to a larger number of shorter sessions. For miniatures I could conceivably finish a project in a single, long, session (though maybe without primer). It makes sense to do the models in batches for this reason, though I suspect more than three at a time would give me real problems until I’m more experienced.
  • I need to mount the models on stands pretty much from the assembly stage.
  • No more brush-delivered old Humbrol varnish except for small highlights.
  • A wash to bring out moving parts is a good idea, but needs to be done quite early, depending on how deep the scoring is on the model. Underpainting may also be a good way bringing out moving parts.
  • I can use my artists paints in the airbrush, but it is helpful to have the same paint mix available throughout the model production for the main colours. The Stay-Wet palette helps here, but it may be an idea to mix pots of more liquid paint at the start so that there is a reserve. The colour-by-numbers approach of hobbyists who buy ready-mixed paints makes more sense for airbrush projects than it does on miniatures. But I’m sticking to my guns – I find mixology way more fun.

My next project on aircraft modelling will be three German planes from early 1943, in desert colours. These feature two simple models – an Me Bf-109G from Hobby Boss and an FW-190A from Zvesda, and an old model, a Stuka from Fujima. But before that it’s back to Napoleonic miniatures.

Starting my airbrush adventure

At long last I’m back to painting miniatures. I am picking up a project started in January: five new regiments of French light cavalry for my Napoleonic army. More of that another time. But as I’ve resumed work, I am starting to rethink the techniques I use.

I first mulled the use of an airbrush some years ago. I held back because the bedroom that I used for my hobby projects wasn’t well ventilated, and I had been a bit alarmed by some of things I read about the need for good ventilation. Lack of ventilation severely restricted my use of aerosol paints. These fears, as it happens, were probably exaggerated so far as concerns the water-based products that I was considering; the spray coming from an airbrush is pretty limited. But the studio in my new home, which now my new workshop, has much better ventilation, so that obstacle was falling away anyway.

Two things brought the issue to a head. First was the incipient new project of returning to aircraft modelling, which I have already posted about. Airbrushes are very much the thing for this these days, as I found when researching techniques. The second came about with my new cavalry, which needed priming. The primer I have been using in the last few years was Fortress Special Metals Primer, bought in 750ml tins at my local DIY store. This proved an excellent primer, by the way. It sticks well to both pewter and hard plastic while taking acrylic paints well. Better it dries in a nice, tight and thin coating. The problem proved to be the massive tin. This wasn’t designed for regular opening and closing. It was hard to prise open, and over time the repeated opening damaged the seal. Attempts to transfer to smaller receptacles were a bit messy, and these dried out rather quickly. By the time I opened it after about 9 months of non-use the remaining half of the tin was completely solid. Receptacle design is an increasingly important issue with me, having lost a number of artists acrylic paints due to badly designed tubes (one reason that I favour Liquitex and now avoid Daler Rowney). I have now ordered some artists’ gesso – more expensive per millilitre, but easier to use, and hopefully leading to less wastage.

I ordered this from Hobby Craft, who are taking their time to fulfil (this may be a function of having now moved out into the country). Meanwhile I found some white aerosol paint (I found two cans, but one gave up after a couple of minutes use). This reminded me of how just much I dislike aerosol paints. In one way they are an excellent way of applying primer. They don’t swamp the detail, which is the risk with a brush, as well as covering large areas quickly. But they are messy; it is difficult to control the spray and there are clouds of propellant, which is smelly and probably not very healthy. I feel the need to stand well back and put the miniatures in some sort of open box so to as protect my other possessions (or to protect from the breeze, if outdoors); and then there is the business of rotating objects covered in wet paint so that each angle is covered. All this palaver leads to mess, and frequently to missed recesses, especially on 15mm or 20mm figures. An airbrush, however, offers a much more controlled way of applying primer (or varnish – less of an issue with aerosols for me, as it isn’t quite so messy). The product gets on quickly and smoothly and you can give each figure individual treatment.

It was too late for my cavalry project, but my imminent aircraft project offered the perfect opportunity to learn how to use the device. My plan is to start of a single cheap model, before tackling the main part of the project. I regret throwing away my three old models, even after I moved them all the way here – they would have been excellent to practice on. And so I embarked on research. There is a lot of material out there. One particularly helpful blog (tangibleday.com) pointed me towards a US Badger product (the Patriot 105). But as I looked for places to buy airbrushes, I felt the need to go to a reputable dealer; there are fakes out there, quite apart from the need for ancillary products. This drew me to the Airbrush Company Ltd (airbrushes.com), which is based in Sussex, not all that far from my new home, though, of course, my plan was to buy online. Their website is particularly helpful, but their principal product range is Iwata, a Japanese company. The tangibleday blog says that Iwata are one of the three best brands (Harding & Steenbeck being the third), which has the reputation of being excellent but expensive. That blog is American, and written a while ago, I think. The balance of cost may be a bit different here and now – the cheaper Iwata products didn’t look too badly priced, given that they are a premium product. This drew me to Iwata.

There were two main candidates: the Iwata Neo CN (£85.80) and the Revolution CR (£130). The Neo is a new product, clearly aimed at the entry level, apparently subcontracted to a Chinese manufacturer. The Revolution was the entry-level series for Iwata before the Neo, and is more robust, according to the reviews. The critical operational distinction between these brushes is that the Neo CN has a 0.35mm nozzle, and for the Revolution CR it is 0.5mm. There is a Revolution brush, the BN, with a finer nozzle (0.3mm), but I ruled this out. Smaller nozzles are better for fine work; larger ones for wider coverage. Another issue is that I needed a compressor to provide the air supply. I decided to go for one of Airbrushes.com’s kits, with compressor and cleaning products, plus some basic paints. These started at £225 for the Neo plus a very basic (Neo) compressor.

After reading reviews for these two brushes it became clear that the nozzle size was a critical difference. One reviewer said that he found himself using both brushes, with the Neo used for the fine work and the CR for the higher coverage tasks. It then struck me that I wasn’t ready to use the airbrush for fine work. I wanted it for applying primer, and maybe varnish, and for higher coverage jobs on model aircraft and vehicles. The Airbrushes.com guide said that the CR wasn’t suitable for miniatures, but fine for models. I also decided that would spend a bit more on the compressor, as this was a pretty critical piece of equipment. So I decided to splash out on the Revolution CR, paired with the Silver Jet compressor for £306. Along with the kit come some small pots of LifeColor paints and thinner, plus three different cleaning products, which is probably a bit over the top. I also bought a basic cleaning pot – so that you can safely empty the brush while cleaning it. It all arrived in a few days.

My new airbrush and compressor (and cleaning pot) in the studio

So how is it working out? I have had one trial session, so it is much too early to tell. For all the complications you read about in the blogs, the technology is quite mechanical and simple, which is a relief. Still there are a number of variables and quite a bit to learn. Covering large areas with a thin coat is pretty straightforward. Doing fine lines isn’t; this may be bad technique on my part, or it may be that this brush has a relatively large nozzle. But fine work was always going to come much later for me. I’m looking forward to getting started on my first model.
