Recently Completed: Airfix 1:72 Hawker Typhoon Mk. Ib (A02041).



This is the first Typhoon I have ever done (though there was a Matchbox 1:72 Tempest II back in the 80s). Tooled in 2013, this kit looks very nice in the box, and as a Series 2 kit comes on four sprues and with two decal options. I had intended to do the more colourful scheme with invasion stripes, but didn’t trust such large decals not to pose grab and alignment problems that might result in tearing; plus I wanted to get this one off the bench before New Year and wasn’t in the market for surprises, or for backing up and painting the stripes.

Another good-looking addition to Airfix’s stable of British aviation in miniature, the model’s pleasing lines conceal a few challenges. I got the feeling Airfix somewhat over-thought the engineering in this kit, especially in the way the cockpit interior locates, and the cockpit floor/wheelwells part, which demands a certain order of assembly and unavoidably introduces the potential for misalignment. Fit problems I found inevitable, steps at the wingroot being the most serious, though gaps manifested on the horizontal tails too: whiteglue to the rescue. I expected the keyed landing gear to be out of alignment also, but surprisingly it was not – the wheels are flattened and bulged, and keyed to the struts, and once the model is “up on its feet” the flat spots are firmly to the ground. Assembly took a little time, and there was plenty of prepainting to do, between the prominent radiator/carburettor intake assembly, the cockpit and surrounds, landing gear, bay doors and propeller assembly.





Overall, though, the model looks the part, and once it was together the finishing techniques flowed along well enough. I used Tamiya’s accurised RAF late-WWII shades (XF-81, -82 and -83) topped with Microscale clears and Florey panel wash, finished with oil wash weathering and Mig pigments. I used the Eduard mask set for the canopy and wheels, and the AML masks for the Type A camo scheme. The set includes an extra sheet of straight strips doubtless intended for painting the invasion stripes.

The best part of the kit was the decals, they were superb and pulled into surface detail even before MicroSet was applied. Very thin, they grabbed a bit quickly, but are of solid tone, fully in-register, and seem especially accurate. They behaved much better than the sheet in the Spitfire I finished last, indeed I completed all decals, with the exception of the leading edge yellow stripes, in a single day of work.





Criticisms? The small antenna on the underside of the fuselage did not fit its locator hole – I fiddled and fumbled with it for a good twenty minutes, most of which was involved in getting hold of the tiny component, over and over and over, while applying a file to the base until it actually dropped into the receiver. The tailwheel is moulded as one part and must be seated before the fuselage is closed, which ups the odds of damage during handling and makes painting the unit a matter of a small brush and prayer. When the propeller is finally installed, the mounting calls for a cylindrical unit to be inserted between four moulded guides which “tension” it into place – why so complicated? The fuselage aperture had to be filed to accommodate the outer ring of the cylinder, and when it slid home it became apparent the outer diameter of the fuselage mouldings is larger than the outside diameter of the spinner backplate, leaving a strip of unpainted plastic exposed – yet with the prop now quite firmly in place there seems no way to tease it free again to paint the strip. Chancing getting camo green on the satin black spinner is not a risk I’m willing to take at the very finish, so it stands as-is, and angle of view will hopefully conceal the flaw for the moist part.




I have another of these, in the “Dogfight Doubles” edition with Pips Priller’s FW 190 (an unusual combination, as the Tiffie found its forté as a ground attack plane and probably never tangled with a 190, at least not on purpose) but it may be a few years before I welcome going 15 rounds with this kit again. There are some lessons learned here, of course, such as leaving the main gear bay doors off until after the struts are in place, which would make it easier to keep the doors aligned and not “toed-in” a bit.

Enjoyable? It’s always nice to see a project come together, but I would have to say I was happy to see this one leave the bench in the end. Maybe the shake’n’bake kits have somewhat spoiled me, but I had hoped for better alignment. Recommended nevertheless, to those with a little experience under their belts.

Keeping it Simple: Academy’s Hellcat


When the weather has hit 112 F out there and you need AC and fan in combination to get through the day, you don’t want heavy, complicated projects, and knocking off some quick builds is the right medicine to break up professional commitments.


I picked up Academy’s 1:72 F6F Hellcat (#2121) on eBay many years ago and it has hung around on my shelves for the last two years or so with some pre-painting done, therefore technically started. I would like to do a USN midnight blue subject in each year, along with another from the grey-over-white era, but my last blue was Academy’s F2H Banshee in 2015 – I was amazed to find years had gone by since the last time I uncapped the blue! This Hellcat is a surprisingly good little kit, very simple to put together (so long as you’re careful with alignments, the wing to fuselage can bite you on the underside) and has engraved detail so looks the part under a coat of paint.


Construction was not difficult, fit is generally okay, though the engineering is not quite up there with the big guys. Options include the small side panel windows to do the -3 variant, and you have bombs and rockets for the -5. Clear parts are well done, with a choice of windscreens for the two variants plus clear plug-in domes for the position lights on the spine an tail light under the rudder. The engine is a decent little rendition of an R-2800 and looks okay with a black wash. The prop shaft seems a bit thick and profits from a swipe with a file. Landing gear is reasonably strong for the scale, and undetailed gun barrels are moulded into the wing halves.


I’ve had disappointing results from commercial canopy masks, they can pull up the paint as you remove them, and it’s frustrating indeed when that happens as the product adds several dollars to the build cost. This time I did it the old fashioned way, using thin-cut slivers of Tamiya tape and Gunze masking fluid to outline and fill in the areas, and the thin braces are custom decals – clear Superscale decal film oversprayed first with Interior Green, then Midnight Blue, and finally Micro Satin. I made a piece 30 x 48 mm and should be cutting strips from it for many years to come. I used my “Chopper” mini guillotine to precision-cut a single strip, which provided the four short pieces necessary (I didn’t get fancy with the 45-degree corners of the bracing strips – tis is meant to be a simple project, after all).



I went with a mixed version of USN Midnight Blue (An 607/FS 25042), as I had read and agreed with the observation that Tamiya’s shade (XF-17) was too dark. I tried the mixing ratio of XF-17 : XF-8 : XF-2 at 5:3:2, this producing a slightly brighter and lighter blue. The original was not a full gloss, so Microscale Satin was the perfect finish, right out of the airbrush. I used the Academy instrument decal and going by the way it went on the kit sheet would probably have been usable, but I intended from the start to go with Superscales for this build, 72-737 being my choice, simple markings for a -5 from an unidentified unit toward the end of the war.


The support straps running under the belly tank should be in natural metal, and if I ever locate my silver strip decals I’ll add them. Likewise with the bombs – lightened Olive Drab for scale effect, but the ordnance decals I remembered turned out to be 1:48th scale, so if I ever find smaller ones I may add them and perhaps a clear coat to dull down the weapons. In the same spirit, when I get some superglue in a fresher state I’ll look at adding a radio antenna, if I judge the mast strong enough to take the mild but constant pull of EZline.


It came out very nicely and is my first Hellcat ever – I built a Wildcat as a kid, if memory serves, but never its successor.

I can’t wait to get a Corsair into this mixed blue – it looks better, to my eye, than any I’ve had out of a jar or can so far. Mind, it’s a good job I wasn’t trying for a high gloss, or I’d have been very disappointed, as I have yet to learn the trick of keeping dust and micro-fine hairs out of the painting space.

Next up looks like being a Spit, and maybe a Phantom is impending…

Cheers, Mike

Kit Review: Fujimi 1:72 British Phantom F-4K (H-8)



About two years ago I posted about the face-off between Hasegawa and Fujimi in the late ‘80s to mid ‘90s period, and particularly their battle for the Phantom marketplace (see The Great Phantom Shootout.) It’s taken me a while but I finally have a review of the Fujimi product to offer.

This particular kit, though undated, is contemporary with their Phantom FG.1 “Silver Jubilee” kit (H-6) which was reviewed in FineScale Modeler in August 1987, and is substantially the same kit with different markings (offering 767 Squadron, FAA, c. 1969-1971, based at RNAS Yeovilton, one of the original units that worked up the Phantom for the Royal Navy. Their distinctive yellow eagle on the tailplane is quite unique and attractive).

Having worked on a couple of other Fujimi Phantoms (as yet unfinished) I was impressed that the company had refined their moulds and engineering approach to simplify construction so the model exhibits minimal seams, and lines up very comfortably. The kit is highly detailed, featuring finely recessed panel lines and tiny elements such as the pressure sensors in the intakes. The cockpit features raised instruments, for which a decal option is offered, and the seats are perhaps the best styrene representations of MB.7s I have seen to date. There are a number of alternate parts on the trees, as Fujimi, like Hasegawa, always pushed its mouldings for maximum versatility, in this case giving you the option of the hyper-extended nose gear leg, open canopies (a single piece canopy is provided for the closed option, which unfortunately does not fit very well at the front, leaving a noticeable gap around the windshield) and open engine auxiliary air doors (which fit so poorly they cannot be posed in the closed position without looking phony). Three other marking options are included, featuring the short-lived 700P Squadron (which only received five planes) and the fleet-service 892 “Omega” Squadron, plus an aircraft of the Phantom Training Flight that replaced 767 in 1972 when they transferred from RNAS Yeovilton to RNAS Leuchars in Scotland.

See the web for histories of the squadrons involved: ACIG Database for a general history of Phantoms in British service; and a close-up on 892 Sq. at Wikipedia. Wikipedia also offers a very useful look at international operators of the Phantom which touches on 767 Sq. FAA.



Parts breakdown is logical and straightforward, with full fuselage halves (as opposed to Hasegawa’s answer to covering the variants, their fuselages being separated into forward and rear sections, which inescapably gives you an extra seam to deal with), and the wing roots are a close, tight fit, requiring minimal dressing. The fuel dump at the tail is moulded with the fuselage halves and is so delicate that if you can avoid breaking it off, you’re a better modeller than most (this is a pet peeve of mine regarding most 1:72 Phantoms, I even wrote to Quickboost to suggest they produce a resin replacement, they would be sure to sell thousands of them…)

Detailing is correct for the British bird, with the recontoured fuselage to accommodate the Rolls Royce Spey engines, slotted tailplanes, and a choice of 600 gallon tank or Vulcan gunpod for the centreline hardpoint. I had been going to mount the gun, but the central pylon is moulded with the wing undersurface, and situated in the declivity between the engine bays makes carving it away impossible without a powertool. I ended up leaving the centre station empty but going with a full battery of missiles, so the aircraft is configured for a medium-range combat air patrol/interception sortie.

Eduard’s Phantom canopy masks are designed for the Hasegawa kits, and while the Fujimi may be very similar, I was more confident to go with a set of vinyls designed specifically for these kits, made in Canada. I've mislaid the backing sheet so can't quote the maker -- unfortunately, as they are an excellent product that worked very well. I mostly airbrushed Tamiya Acrylics, XF-2 for the underside, and substituted XF-63 German Grey for the Dark Sea Grey. Gunze 333 is an exact match but can be hard to find here; Gunze is also a brand I have no experience using so far. XF-63 may be a tad dark, but RN Phantoms look a different shade in every picture, from pale grey to royal blue… The metallic areas were painted with Model Master Chrome Silver enamel as my metallic acrylics have been misbehaving lately. The radome was Tamiya X-18 Satin Black, the afterburners X-10 Gunmetal. With prepainting thoroughly dry a long round of masking ensued to protect metallic areas, intakes, canopy and radome, then the underside was sprayed, along with gear bays, doors, struts, pylons, rails, tanks and missiles. Another round of masking established the wrap-around of the topside grey under the leading edge, then the XF-63 went on. Main coats were allowed to dry overnight before further attention. Next was to unmask the last round only, do any touchups required, then get arty with black and dark brown oil washes, laid on with a small flat sable brush. This simulated the Phantom’s characteristic oil leaks that stain the pure white of the underside from the front of the engine bays backward, and behind the flaps and airbrake junctures. This was a surprisingly easy task, and when complete and dry I laid on a coat of Micro Satin acrylic clear to protect everything.



The panel lines on the underside were accented with Promodeller Dark Dirt, as were lines on all the other white-painted items. The topside could have been treated with their Black wash, but I was in two minds about whether it was necessary, given the way the clear makes the panel lines visible. If I change my mind I can always treat them in future. More clear sealed the panel lines, and I tackled the decals.

The decals as supplied in the kit are extensive, with hundreds of items of stencil data complimenting the unit markings. The kit plans are fairly inaccurate in terms of placement, especially as data placement varied among the four units on offer and they only wanted to provide one full set of data drawings. The boxtop art is in fact far more accurate and I followed it in conjunction with photographs sourced from the web. Three kinds of ejector triangles are supplied, and the plans recommend large ones with heavy white outlines. None of my reference photos show this type, and I used the regular, borderless style.

A major difference is that the plans suggest the underwing serials for 767 Squadron should be wholly situated on the fixed portion, however photographs clearly show that all aircraft of 767 Squadron have serials overlapped the folding outer panel by a large margin, which translates into a discrepancy of nearly two metres! I have in fact so far found only a single reference photograph that shows a British Phantom of the period without the serials overlapping the outer wing panels (an RAF FGR.2 in the camouflage era). I have found at least two examples of profile art showing 892. Sq. planes without evidence of serials on the outer panels, but artwork can be based on incorrect information. 767 Sq. is firmly supported by the photographic evidence and if the serials are correctly positioned according to these sources, some stencil data supplied in the kit must be omitted as it is designed to be used with serials positioned closer in... The jury is out, as they say, but I’m going with the photos for this subject.



The big underwing serials are also potentially hairy to apply as they cross the attachment points for the outer pylons and fractionally overlap the gear doors as well. Obviously, the pylons go on after decaling is complete, for which one may be glad the fit is pretty excellent and tiny dabs of CA at the locator pegs alone will do the job. All serials begin “XT 8…” so these characters are supplied as one decal, with a set of extra digits to depict any of the four aircraft. The parts that overlap open gear bays, well that’s up to your creativity. Cut the decals and apply the slivers to the doors? Shave away the overhang and paint the disembodied bits?

All this is excellent and quite clever, the decals separate cleanly, albeit after a lengthy soak, but I can honestly say I have never seen decals “silver” so badly. Not all of them, certainly, but many, and mostly the tiny stencils. Even over clearcoating and using the Microscale chemistry they were not all that keen to conform to underlying detail, and after a day’s drying the silver bloom in the clear film was a great disappointment. The needle-prick method helped, but was by no means a cure. Using a sharp blade and Future also failed to improve matters. Decaling took four days, a total of 154 items being applied (plus a dozen pieces of coloured strip from an AM source for the missiles, and fragments of the large numbers that ended up on the bay doors), and while it’s pretty comprehensive, some of the decals are also out of register. The British roundels are perfect, but the yellow in the eagle is notably “over the line” and some small items backed with white show a distinct rim of their base. I did check online for an AM sheet depicting Phantoms of 767 Sq. but could not find any currently in production, nor early FAA stencil data, and I also wanted to get this project off the bench, so persevered. I found stencil data by AirDoc, but only for RAF birds in the camo and grey era, so again the kit sheet was the practical alternative.



I made a mistake when clearcoating the decal work, in underestimating the tenacity of the decal fluid residues. I did not wash the model adequately and though the fluids are invisible against the paint they show up instantly a clear is applied. There is also zero you can do about it other than strip the whole job and start again, which I was not willing to do. There are random flat patches in the finish now, though I managed to spot the problem and properly wash remaining areas, so the left wing at least is free of the issue.

Fitting the landing gear when all painting was complete reveals a lack of proper alignment. The assemblies are detailed and look great but there is no way to adjust their alignment. When they drop into the locator holes, that’s it, and the main gear plus retraction struts sit toed-in and canted in, which looks wrong. To combat this in future I would assemble the legs and struts, trim the locator pin from the strut and seat it with CA wherever it falls when the gear is straight, and leave it at that. Retraction struts are also supplied for the inner doors but I left them off as there is no way I could see for them to ever line up with their locators. The small doors are also very weak and I could not count how many times they simply fell off in the course of handling.



This model is not one of my best and some of the problems can be attributed to the kit, some to my own skills. It looks good on the shelf, but under the magnifying glass the issues with uneven paint, masking problems, decal silvering and residues, and visible gaps where the pylons meet the wing despite all filing and pushing and pulling, plus the gear stance, make this one a learning piece. Applying the lessons learned here to a larger scale may return a much better result.



In conclusion, the Fujimi F-4K is a good kit, though not a perfect one, and a skilful builder with experience working with paints and decals can produce a very nice looking model, though there will be a fiddle in a few places. The kit counts as “vintage” but can be picked up on eBay from time to time for reasonable prices.

Simplifying Soft Masking



Back when I started this blog, one of my most-viewed early posts was about detailing Hasegawa’s Bf 109 K-4, and one of the techniques I explored was soft-masking, cutting card masks for the camouflage and applying them clear of the surface by an eighth of an inch to hopefully create soft-edged demarcations.

I have been putting together Hasegawa’s Bf 109 F-2 in markings for Operation Barbarossa, and when coming to soft-mask the camo this time an interesting twist struck me.

I had not particularly thought about the masking until I got to the relevant stage, then I compared the pattern on the K-4 to the one on Werner Molders’ aircraft to see if the same masks would serve, at least for the wings and tail, but the pattern, being hand-applied on the original aircraft, was different enough to warrant a new set of masks being cut.

Rather than a process of trial and error, holding pieces of card to the model and trimming them until they looked about right, and in the absence of a 1:48th scale reference drawing, I pulled another unbuilt 109 from my stash and laid the wing, tail and fuselage parts onto a sheet of light card, ran a pencil around them and abruptly had my profile plans. From that point it was an easy matter to copy the camouflage from the kit plans onto the sketch and outline the segments to be cut out. It doesn’t even have to be very exact.

The virtue is that you can pre-design cutaways to fit around the wings or to run under the tail surfaces, or long tapers to shield the sides of the fuselage, helping reduce tape usage. And, if you’re careful with the cutting out, you’ll have a negative mask as well, which you can lay over the opposite tonal area to touch up overspray if needed.

On this model I’m using Model Master Acryl paints (well, on three models simultaneously, in fact), so look for a review of these paints in the near future.

My too-full schedule has been cleared somewhat lately, so look for new posts rather more often.

It’s Good To Finish



The Italeri Corsair is done, which unless I am mistaken constitutes my first finished Italeri kit ever. In some ways it was excellent, in some ways a PITA. The wing alignment defeated me long ago, but now it was nothing to break a sweat about. All the same, this kit had a way of fighting me right to the finish.

Such as… Why are the holes for the drop tank pegs too small, so you have to file them out after the paintjob has been so carefully applied? The pitot tube was moulded with the wing, and there was no way it was going to survive the years. .020” microrod to the rescue, and a little superglue. Same with that row of antennas around the fuselage, it might make sense to fit them before painting but the handling that comes from that point onward is still enough to do for them. They were finagled back into place with CA at the finish, and one which disintegrated before it could even be installed with replaced with 7mm of .020” rod. The original was a blade antenna, this one is rod. Tough.

The canopy masked nicely, but I could have wished it unmasked a bit cleaner. What is it with clear plastic and its ability to gather scratches?



The gear bays were masked after main painting and sprayed with a homebrew interior green (Tamiya XF3 and XF5 at 3:2, works every time), then overspray was touched up on the hull (yes, there was overspray no matter how much masking I used… Like this: )



The tires were brush painted in NATO black, the rim is moulded high enough to guide the brush and inconsistencies are invisible against Dark Sea Blue. Another problem, the main gear seemed to want to sit a bit knock-kneed, so I cut a 50mm spacer bar from styrene strip and braced them apart while the gel CA set up overnight. Now they stand straight...

The gear bays were given a quick black oil wash, then I added a little MiG dust in them, and did the exhaust streaking with their Black Smoke and Vietnam Earth pigments; only the red earth shows up, as you might expect. Hmph – and why is it that you discover when you’re finished that you could use MiG pigments to take fingerprints, because they certainly only show up on the model as you’re putting the finishing touches to it!



One day I might get around to chipping paint with silver but for now I’m just happy to have the project somewhere I’m willing to call the finish line. It’s great to call a completion, file the unused decals and plans, bin the empty sprues and bags, and wipe down the bench ready for the next kit, it brings a sense of progress which few other moments do. This is my first completed Corsair in many years, but I’m sure it won’t be the last, the bent-wing bird is way too much fun to leave alone for long!

Attitude: Resisting the Fiddly



Perhaps it’s the same phenomenon I was discussing last time, a mental blockage that keeps you from either seeing a solution or, just as importantly, implementing it.

I began building a Hasegawa Kyofu Rex seaplane a week or two back, a project I’ve wanted to do for ages and finally found an excuse to as another test subject for trying out those acrylic topcoats. The model fell together like a dream, there are only 37 parts in the plane and a few more in the handling trolly (the German would be dockwagon). The acrylics are all lined up and ready to go, the only obstacle was masking the canopy. Eduard make a set for this kit’s bigger brother, Tamiya’s 1:48 scale equivalent, but for the one-piece canopy of the little guy I was on my own.

Well, slivers of tape must be coaxed into place with fine tools, obviously. But it took me a week or so to commit to the task. I felt like Sgt. Pinback being told it was time to feed the alien, in Dark Star… “Ohhhhh, I don’t wanna do that… I have to do everything ‘round here…” Maybe it’s my deteriorating eyesight, or persistent memories of being frustrated by such tasks before, but it took resurrecting that Corsair a few days ago to get me to the job. Eduard makes Corsair masks but it would be weeks before I could get hold of them and they cost money, a few slivers of tape are immediate and essentially cost nothing.



So, the mind sees the necessity, the heart deals with the angst, and the hands and eyes do the job. A couple of hours work spread out through the whole day so there’s no chance to go stale on the task, and I had both canopies outlined. From there it’s easy enough to backfill the areas with tape. One concession to the approach is that it’s obliged to be a two-part finishing process: main struts will be painted, fine secondaries, simply too small or intersecting in complex ways with the others, will be slivers of decal, which will be made from clear sheet at the painting stage.

The pre-cut masks are so convenient you forget grass-roots techniques like these. I’ve not made slivers of decal for canopy struts in 15 years, so it’ll be an interesting experiment to see how they work – or don’t. If they don’t, I’ll figure out some other solution.

Product Review: Tamiya Masking Tape



I remember building Revell's prototype F-16 when I was a kid, in the early 1970s, the one painted up in red, white and blue. The kit was molded in white so I let the white areas be raw plastic, and masked the hard-edge red and blue. I used cellotape, which over raw plastic had nothing to pull up and gave razor-sharp demarcations. I was very impressed with the edge work, less so with the finish of flat enamels slathered on thickly with a brush, and which somehow managed to migrate under the tape where it crossed detail.

Not long afterward I tackled Monogram's B-52D, painting the whole thing with a brush in Humbrol enamels. The white underside took coat after coat and must have looked like it had been done with a roller... Due to the size I used automotive masking tape and of course discovered the necessity of de-gluing the back. Even over well-cured, thick enamel the tape had a de-surfacing effect that was not attractive. I had planned to mask and paint the walkway stripes over the NMF but after early experiments abandoned the idea. Somehow paint would always migrate under, no matter how well-burnished the tape edge seemed to be...

I used to think joint dressing was the biggest drag in the hobby, but since the advent of both cyanoacrylate glue and better-engineered kits joints have become simply a part of the process, not the disfiguring headache they once were, and the necessity of masking the paintjob has rather moved to the fore as the most time-consuming task in reaching a really good result.

Household/automotive paper tape is not designed for delicate paints and you need to seriously de-glue it to stand a chance. Scotch brand invisible mending tape is not very sticky and produces a very sharp edge. The problem with these two is they are not very flexible, they don't deform easily around corners. In the US there is the blue 'painters' tape,' but I'm not aware of it (or an equivalent) in Australia. To be fair, I've not checked out hardware stores for the item, but there's not much point when you have an item like Tamiya tape in the tool draw.

If there was a perfect product for this application, I'd have to say Tamiya have nailed it. Their tape is low-tack, burnishes down tight, deforms readily, and peels off clean. I have yet to have it pull up sprayed acrylics or enamels over any properly prepared surface (the only time I had it take paint off right through to the plastic was attributable to a deposit left on the surface of the model by the cleaning agent I had used to degrease it). The tape is also essentially re-usable, I have used the same pieces of tape on multiple projects, simply by transferring them to another plastic surface where they can stick for weeks or months and again peel off cleanly.

The tape comes in a variety of widths from narrow to broad so you have the option of curving lines or bulk coverage. I usually put a strip down on my cutting mat and slice it up with a razor knife and steel rule into ultra-narrow pieces or shapes as the job calls for. The dispenser rolls are a good idea, too.

The FW 190 I have on the bench at the moment was masked in both hard and soft contexts. The unit markings featured yellow rudder, cowl and fuselage bands, and rather than go with the kit decals for these items I sprayed them at the same time as the rudder. After overnight curing I masked them with strips of Tamiya tape and carried on with the rest of the paintjob. Several days went by, then I removed the hard masks and discovered perfectly sharp edges, and perfect protection of the underlying paint from later applications.

The big resin Beta-1 bomber featured in the last couple of posts was also fully masked with Tamiya tape, a long and complex operation, but one which went off essentially without a hitch. The colour demarcations are as tight and sharp as you could possibly wish for, with absolutely no paint bleed-under or de-surfacing on removal.

Tamiya tape is an indispensable tool in my kit, and I recommend it without reservation.

Product Review: Alliance Model Works Painting Masks




 Now here is a truly good idea! The template painting method for wheels has been around for quite a while and it makes a slow, tedious, “iffy” job into a quick, accurate one, but one painful truth is that models are a scale depiction of reality and as such it’s always a lottery as to whether artists’ circle templates, which are produced on whole millimetre increments (they don’t seem to make half-mil sizes) ever match closely the size of the wheels. After you’re done spraying you always need to take a fine brush and clean up those edges by hand, hoping the ridge of the rim will guide the brush adequately to fool the eye. For a Panzer IV, with 36 wheels (counting the spares), all of which should correctly be rimmed both sides because you can see the hub area of the rearmost of each wheel pair from oblique angles, that’s a formidable task. But Alliance Model Works have come to the rescue with photoetched painting masks, circle templates designed to fit the rims of specific kits from specific manufacturers.  

 I ordered their set for WWII Wermacht tanks and other vehicles on eBay. #Lw3574, “German Vehicle Wheel Mask Set” comes attractively packaged in a conventional plastic and card sleeve, containing a sheet of instructions on the use of the product and no less than three frets of etched stainless steel, plus one ‘loose’ mask for a total of 54 templates for roadwheels, return rollers, and the steering wheels of halftracks, plus even the wheels of some towed fieldguns. These are precision-made items designed to fit exactly over the rims of kits by Tamiya, Dragon and others, which means no more touch-ups: once spraying is done, you should be finished the job. As soon as I saw these gleaming, individually-plastic wrapped frets I smiled and said to myself, “if these work as advertised, a hard job just became easy.”  



 I tested them on the Tamiya StuG IV crossing my bench at the time. I had delayed doing the wheels til last, and I was very glad I had. The first step was to paint all the tyres black, for which I mixed Tamiya XF-63 Panzer Grey with X-18 Satin Black for a low-lustre tyre black (1:1) and sprayed the wheels on the sprue for ease of handling, with their mating faces masked with Humbrol Maskol and some wet tissue. So far so good. Then I cut the protective plastic over the appropriate PE sheet and test fit a wheel hub into the “Tamiya Panzer IV” template. Well, I certainly hope it fits the new-tool Tamiya IVs, because it sure doesn’t fit the old ones! Why can’t anything ever be easy? Would it have been too difficult to have the new and old-tool kits (which are still widely available under more than one label) catered to, side by side? I had a choice: use the specified template, biased to slip around the rim on one side only, then come back for a second pass to get the other side of the rim with the template biased the opposite way, or find another template which was large enough and fit close enough to do. Compromise is not what you expect from a precision product, and not what was advertised, but I guess the company is playing to the high end of the market, and nobody said anything about the vintage of the kits catered to by this specific set: there may be another set with the older Tamiya Panzer IVs among it’s many template sizes. I don’t know, I haven’t checked – yet. The good news is the template for Dragon’s Panzer III is quite close enough to do. I stripped the protective plastic away and test fit a hub, finding the clearance quite snug enough for my purposes. The rear wheel of the old Tamiya IV seems to be a smaller rim diameter, but the backs of the wheels are not going to be seen much, so some overspray won’t make any difference. I could have taken the template from the PE sheet but for ease of handling and storage I decided to leave them all of a piece. This is how I’m used to handling plastic circle templates to do the job in the past. I masked close round the hole with tape to keep the product clean overall, then trimmed the wheels from the sprue, leaving the attachment points to be dabbed into the mixed black at a later point (before weathering).  




 I mixed Tamiya XF-60 at 1:0.5 and shot at my usual pressure for the Paasche #3 tip and needle, and did two mixings, one for the fronts, one for the backs, and had enough to double coat a fair few hubs in each batch. The metal sure collects overspray, moreso perhaps than plastic templates seemed to, I had to keep wiping the paint away with a moistened tissue, but that’s to be expected and no problem to deal with. The best news is they work great. Any remaining degree of “wiggle room” is due to the fact I’m using them on a kit they were not designed for, but they’re a lot closer to right than standard template sizes, so the job was right in the end. I know how well they’ll perform when I build a Dragon IV, or III, or whatever else actually on the sheets comes up for building. They were on special but not cheap: still, as a precision tool that will serve me for many years, I consider it one of my better investments. Now when I build German armour, I will reach for these masks as a reflex, and the prospect of the running gear will not be a detraction from the fun of the project. Look at the finished job (mains and spare wheels, prior to fitting the stand-off skirts) and there was no hair-tearing involved in getting there:  


Very highly recommended – I suddenly find myself considering collecting any other mask sets they offer, American armour, Russian armour, they all have rims to paint!

Product Review: Eduard Masks

 



 There are all sorts of tools and supplies in the modelling hobby, and it’s a fair criticism to ask if the modern hobbyist is well-served or merely gadget-dependent. When we need to mask something we use tape, like any tradesman, plus cut paper and card sections for big areas, and we may also use a liquid latex masking medium, an aid brought over from the graphic arts. I always masked my canopies with tiny slivers of tape, but there are some curved that just don’t want to be masked around. A three dimensional shape needs to be expressed in two dimensions, and that’s a hit or miss proposition unless you’re a spatial dynamics expert. Another trick is to spray the hull color on some clear decal film, cut fine strips and apply the canopy struts as decals, and there’s a lot to be said for that technique. There have been a few ideas over the years, including precut vinyl negative masks which are to be sprayed in the final colour and applied, but Eduard might have hit the best formula with their masking technology. Eduard Masks are die-cut adhesive shapes matched to the intended kit at very fine resolution, and the principle of their use is dead easy: peel them off their waxed backing paper, stick them on, spray, peel off when done. If engineering firms go by the old “KISS principle,” (which stands for Keep It Simple, Stupid!), then they’ve probably hit the money. If the hundreds of sets in their range are anything to go by, modellers agree. 




 I’ve used four sets so far and have several more in hand. Though the principle is simple, it takes a fine hand and a keen eye to get them into place precisely. Without magnifying specs I’d have no hope, though that’s more a comment on my vision than the product. The masks seem to be a vinyl or paper material, and their adhesive is quite strong, they won’t move until you want them to, and then they come away without leaving a residue. They can be repositioned, though with care as they will crease and denature if handled roughly. They fully cover smaller panels and outline larger areas, which are then filled in with liquid or tape.  



 Once located to your satisfaction, spray the cockpit interior colour, then overcoat with the camo or framing colours, and when fully dry tease up a corner with the point of a knife and draw the masks away with tweezers. You might also want to hold the canopy down with a finger as you do so. The adhesive is strong enough to pull a clear part off if attached only with clear parts cement.  



 Masks are also supplied for other parts of the model, such as wheel rims and formation lights, and some armour sets have been produced to help with the fiendish job of painting the tires of tank wheels. Hopefully we will see this range continue to grow, as their utility is considerable. Can you re-use a set? I’ve not tried yet, but if you peel them off carefully and return them to their original positions on the backing sheet, it might be possible. Two uses would be good, as they do cost a few dollars, a nonreimbursable expense on the cost of doing a model which is far greater than that of the paint one uses, and often comparable to that of a selection of AM decals. Probably the best tribute I can pay to the product is that when I decide a particular model is on my schedule, I check if Eduard have masks for it and order them up in plenty of time, just as I would order AM decals or resin bits or whatever, and that makes them a tool of choice for this particular finishing operation. I recommend them to any hobbyist with a steady hand and a magnifying glass. Eduard Masks are available in hobby shops and through many online outlets, I always order mine from Squadron Mailorder, Carolton, Texas.
