A Lifetime Since My Last Skyhawk


The Airfix 1:72 A-4B Skywawk (A03029) is the first Skyhawk I’ve done since I was a kid – and that one, some 44 years ago, was also an Airfix, the ancient-tool original! I’ve wanted to add those classic Douglas lines to my display case for a long time, and the new Airfix seemed an inexpensive place to start.


This is a nice kit to put together for the most part, but can bite you here and there. Alignment is generally fine but there were gaps at the wingroots and intakes. The former I dressed using white glue and capillary action, which seemed to work quite well, while the latter received traditional filler, though the repair is by no means invisible. The canopy fit is fair but can wander around in terms of seating the windscreen, while the main hood is too deep – it stands high at the rear hinges, as if designed to be displayed in the open position. There are delicate and fiddly parts, the landing gear especially, and I had to take a few days break to let my frustration settle down before resuming the job. The secondary strut on the nose gear snapped on the sprue and was simply omitted, in the interests of sanity.


Paintwork is MM Acryl Gull Gray over Tammy flat white, with Microscale Satin for the lustre. The decals are very good, but large ones grabbed very fast, resulting in the loss of one of the large NAVY titles – I’ll replace it next time I do one of these kits. Areas where multiple markings lie close together are served by single decals, which is a good idea, except that with the grab of these thin, lovely printings I dare not even try them – I cut away the modex numbers from the front insignia and applied them separately. The same would likely work for the rear flank decals – separate the elements and maybe they’ll slip better.


There are a number of omissions in this build – mine, more then the company’s. There is no decal for the “barbershop pole” effect on the arrester hook, and after attempting to cannibalise strip decal, which shattered at the first attempt, I dropped the hook into the receiver without glue so I can come back to it at a later date if the means comes to hand. Likewise the red edges of the gear bay doors are ignored – way too hard to freehand paint and I’ll need strip decals of some sort (reliable ones…) before I try. The intake warning markings are painted freehand around the curve (the sheet provides straight decals for them, which must be some sort of hobby company joke), and masking the correct narrower area for brush painting simply did not work. So it was brushed up to the adjoining panel line, and that was as good as it was going to get.


I’m more or less amazed that the landing gear is actually strong enough to hold the model up, but it seems to be. I had visions of its collapsing once the tanks were on, but superglue seems to have pinned everything up well enough. The Eduard masks for the canopy were their usual breeze to use, and their usual frustration when they pulled up both paint and decals as they came off. There are times I wonder why I bother to use them when the result is so shoddy -- then I imagine trying to hand paint canopy struts and I remember why.

Overall, a good model that looks the part on the shelf, but I’m reminded yet again that 1:72nd scale is a real trial, and I prefer 1:48th – so long as there’s somewhere to put the finished article. While doing this one I had the urge to grab a late-tool F-16 in the larger scale and just do it, but sense prevailed. Until that fabled new display case puts in an appearance, I must restrain my urge to build bigger!

Cheers, Mike

Kit Review: Tamiya #35156 M1A1 (ODS) MBT



What is there to say about this kit that hasn’t been said before? Probably nothing. But it’s a good one and deserves to be revisited. It’s commonly available and while the accuracy brigade are quick to point out the many flaws (more in the nature of omissions than flaws, really) it builds with typical Tamiya ease straight from the box and the finished model captures the stance and feel of the Abrams.

The M1 Abrams Main Battle Tank is one of a handful of vehicles that seem to have reached a plateau in the development of armour. No new MBT has been designed in America in 33 years, there has been no need because the M1 is largely invulnerable to other tanks, is invariably lethal to them, and after three decades in service is as much an institution as the M16 rifle (which has been around for five). In that time model companies have produced a lot of kits, some better than others, some more buildable than others, but not a single one is 100% accurate, not even Dragon with its patented slide-mould technology. Experts have done the work for the modeller having an attack of AMS (Advanced Modeller Syndrome), you can compare several of the top kits at Vodnik’s site, while a complete list of necessary modifications to accurise any particular kit, assembled by those highly versed in the m1’s anatomy and evolution, can be found here as a downloadable .pdf. On the basis of that .pdf, there are a great many details I overlooked, but I’m not quite so afflicted with AMS that I am up to putting 1:35th scale split-pins and retaining chains on bolts. I can’t build an Abrams without doing at least some superdetailing, and I have done more on this one than previously, around 18 physical additions, plus AM decals and every finishing trick I can think of.



This kit was a retooling of Tamiya’s early-production M1 of 1982, produced about a decade later to reflect vehicles used during Operation Desert Storm in 1991. Basically it is an early generic M1A1, identified as such by the 120mm main gun, revised MRS, main sight, ammo blowout panels and crosswind sensor, smoke grenade stowage boxes, long turret stowage bins, and of course the “bustle rack” for crew gear stowage. The only hull modifications are the NBC environment panel on the port flank (which is missing an important detail) and the cutaway rear panels of the skirt armour.

Assembly is largely based on the 1982 original and the kit falls together as well as it ever did, the only hitch being a tiny mismatch in the upper hull to rear hull joint line, which calls for a bit of finesse and maybe a lick of filler. It’s largely up to you how much superdetailing you want to do, some details are easier than others. Drilling out the solid-moulded towing lugs fore and aft is a no-brainer, and adding missing bolt heads from slivers of styrene rod is another easy one. Relocating the portside grab handle on the forward hull about a scale foot forward to its proper location is another easy one. I also floored the bustle rack with Voyager's photoetched wire mesh part, a distinct improvement on the vinyl mesh supplied in the kit.



Tamiya missed a host of details. The “Z-springs” that tension the hinged forward mudguards are still absent and are easily made from bent spring steel wire. On the NBC panel, a triangular fillet is needed, with a hole drilled to represent the crew heater drain; likewise, the cabin heater intake is missing from the port flank hull and can be made up from a few small pieces of plasticard. On the starboard flank, under the edge of the turret, the bilge pump outlet is missing (only Trumpeter seem to have nailed this detail), and it can be scratched from card and brass tube. A bracket was missed from the hinges of the rear engine bay doors, and some plates and lift lugs too, all easily scratched from cardstock and wire.



A major criticism is the running gear (above), as the return rollers and idler axle detail are entirely spurious. I had been going to rebuild it all, including the track tensioning piston on each side, but realised that it would be wasted effort. This tank has side skirts and not one item I just mentioned is ever going to be seen, so why bother? The T-156 track is not accurate, the guidehorns should be between links rather than centred on them, but, that said, Tamiya’s T-156 track is the most accuarate in any kit, whether vinyl or styrene (according to Vodnik), and the only replacement set is both very expensive and of the dreaded individual link variety, so I was very happy to overlook this point (as discussed in my previous post).



Assembly was largely trouble-free and the most fiddly and frustrating jobs were late in the process. The barrel of the 7.62mm MG was snapped on the sprue, as was one of the tow cables, and they required very delicate repair with cya, and the antennas are fully scratched. The shorter mast I always make from .015” wire, but the heavier, taller mast I make by scraping .035” rod thinner toward one end, then bending it and CA’ing it into place. The tiedown is usually a plaited bungee chord, and for that I used spandex thread (EZ-line, rather simpler than unpicking elastane thread from a pair of nylons, like I did last time I built an Abrams!), twisted repeatedly, and this took three attempts and a large part of an afternoon. Tying knots with tweezers is my least favourite thing (barring L&L tracks…), but it makes a pretty realistic tie-down. The plastic balls on then ends of the masts are made by dipping the tip repeatedly into paint, and the flexible spring-type mounting at the base of the big mast was done with strips of tape, painted metallic. Trumpeter moulded this part properly, and Academy did so, on other subjects; I doubt their Abrams kits feature them as they were cloned from Tamiya’s.

I used Echelon decals which went on without a hitch (but for one which flicked away from the scissors and vanished) and my only criticism is that they are rather glossy. For that reason I held off on a final round of Mig pigments as I’ll see if I can source a decent clear flat to take the shine off the decals first. One task in pigments that came out very nicely was the burned metal on the transom above the exhaust vents (below), accomplished in seconds with two shades, Vietnam Dust and Black Smoke.



To this day Tamiya provide only tiny scraps of clear plastic for the periscopes, a great let down. I replaced them with styrene inserts and painted them all gold to suggest the prismatic tone of the real deal, but I was not very happy with the way they turned out. I would prefer to look for an aftermarket substitute in future.

Overall paintwork was Testor Model Master Acryl #4812 US Army/Marines Gulf War Sand, a non-FS shade originally mixed from available supplies in-theatre. It went on very well indeed, though my surface prep could have been better, I found myself respraying some spots around the front end when masking took the paint straight off. The tracks, as detailed in a separate post, were done with mainly Tamiya Acrylics.



The finished model looks the part and has enough extra detail to satisfy my desire for accuracy without breaking the bank re my bench hours, or my pocketbook. I could go on, but… Who looks under a tank model to know if the hull bottom is accurate? To be fair, the next Abrams I build will be Trumpeter’s HA and one of the Dragon offerings with all kinds of fine detail, including non-slip texturing moulded in: I ignored the necessity this time as there were some –A1s in Desert Storm which had not received the coating when they went to the Persian Gulf, so I can claim at least some accuracy. I’m happy with the model, my first Gulf War armour, and feel this kit, despite its age and legacy of parts from 1982, captures the design well enough to provide a solid basis for superdetailing, while avoiding the fit and assembly issues reported of at least some of the kits which offer superior detail right out of the box.

Not Retiring Enamels After All



Real life has been in the way bigtime, it’s been three months, to the day, since I had a chance to post, but finally I have the time and something important to look at.

Last year I posted a speculative point that acrylic paint technology had almost reached the point that it was worth retiring enamels altogether, for their toxicity and stink. How many of us spray outside to keep the fumes from offending the family? And mortgage our health in any case, as unless we can afford a proper industrial respirator, we’re going to breathe in at least something of the atomised hydrocarbons or whatever other noxious fumes our airbrushes emit.

I have spent most of the last year studiously avoiding enamels, my last enamel job is awaiting completion, and that last camo shade will probably go on with acrylic anyway, just like the topcoat. But where metallics are concerned, acrylics are just not up to snuff yet.

Reviews of the original Tamiya range many years ago reported a granular effect from their silver, and though their paints are now better made, more finely ground or whatever, that granularity is still with us. Add in difficult conditions of temperature and humidity and you can have a mess.

I recently set out to do the natural metal parts of a whole line of Phantoms, and Tamiya acrylics only wanted to spatter and dry like pebbledash paving. Next I gave the Talon brand another go, but I don’t think I’ve encountered a more unfriendly and delicate formulation. I ended up with five sets of tail fins to sand clean for the second time, as the ‘gradual build up of mist coats’ technique was gradually building up little more than … pebbledash pavements.

In frustration (and as I had an hour with the family out) I pulled out an ancient bottle of Model Master Chrome Silver. There was a tiny bit of sludge at the bottom and I was about to bin it, but decided to give it a go anyway. Tamiya X-20 enamel thinner reconstituted it perfectly and it went onto the engine areas of five Phantoms without a hitch, and without the spatter effect that has had me convinced lately my airbrush’s #3 needle needs replacing.

I should have just sprayed everything in enamel and given the Talon a miss, then the whole job would be done. After masking I can do the darker shade in acrylic, Tamiya Aluminium and Gunmetal are far less temperamental than their Chrome Silver, but for the bright base it turns out there really was no alternative. I’m not saying the Talon paints aren’t excellent, but they’re a technique that takes practice, and a patient hand, and I hope one day to have the chance to find my feet with it.

For now, I find myself thinking again about that fumehood setup and respirator for the hobby workshop ("mancave," is a common term for it, but that's sexist, there are plenty of great female talents in the hobby) that's out there on the horizon. Enamels really do flow on so beautifully… It’s a pity they’re poison.

Now That’s What I Call Shelf-Life



 I have rarely had cause to need gold paint. I have always fancied doing that gold-painted F-16, Sioux City Special I believe she was called, I even have a kit and decals lined up for the day I have the time... The chance... Somewhere to put it... But the odd gold detail might call for having gold in stock. I have a tinlet of Humbrol #16, Gold. I recently needed to open it for a few dabs of gold to visually blend in some gold foil I was applying, and sure enough, there it was, in the box at the back of the drawer. I really don’t remember if it was ever opened to do a job, but I am sure it was bought to do the gold detail work (engine accents, IIRC) on a small kit of the Honda CB 1100R motorcycle, by a firm called Crown. I bought that kit around Christmas 1982, it may be the oldest single article in my stash (still unbuilt). And by default, that means the paint is now around 27 years old. (The pic above is a new tin, I can’t seem to lay my hands on the old classic…) It wasn’t even thick in the tin. I gave it a shake, opened it and stirred it for thirty seconds, and it was good to go. When that paint was manufactured, that expression wasn’t even in use, nor were in the pipeline, 24/7, on track or my bad. That’s what you call shelf-life! Maybe the pigments weren’t as finely ground in those days, and the available ranges were smaller, but the chemical balance of the paint in the tin makes for a virtual time-capsule: so long as the balance remains within certain margins the mixture should remain viable forever. Of course, there are other tins that go hard while you look at them, and I had a bottle of MM enamel whose contents turned into a strange, rubbery substance without ever being opened, or maybe only for a tinting dab, but this is where chemistry meets philosophy. The same thing happened recently to another bottle, much newer, something to do with failure of the foiled card seal in the cap, I think. Folks have been complaining on other forums about this and other shortcomings of the Model Master range, lately, which is a pity as it’s really good paint, just let down at times by packaging issues (and accuracy issues, like the identification numbers of the RLM 82 and RLM 83 shades somehow getting reversed when the labels were printed… Or their Dunkelgelb being a bit on the dark side…) For the moment, I’m very impressed with Humbrol. Of course, the delicate balance of chemistry in the tin has been disturbed now, and the next time I look at it, it may have congealed, disintegrating like a vampyre whose coffin was opened before dusk. I guess we’ll see when it comes time to build that F-16 (unless I’ve graduated to Talon Acrylics by then...)

Acrylics or Enamels?

 



 It has to be the biggest question in model painting today, beyond choice of brushes or airbrushes, beyond colour selection: which type of paint is best for your project? There are modellers who have switched entirely to water-based acrylics for all spray work, for the health benefits: nontoxic paints are a major factor and not to be taken lightly. When you’re used to the light, sweet smell of acrylics and their water cleanup, to start spraying solvent-based paints and their spirit cleanup is a rude reminder of just how frequently and casually we poison ourselves with the things we invite into our environment. Got a spray booth with a ducted exhaust fan? Good for you, but most of us make do with an open window and sometimes it’s just not enough.

Like many modellers, I have both types of paint in stock. I first bought acrylics when tackling vinyl subjects in the early 90s, and I must say the Tamiya paints I bought have been extraordinarily long-lived. They’re still good over 15 years later, all they need is a stir. They haven’t made the old, large bottles in many years, possibly because people discovered the paint lasted remarkably well, and for the rate of usage a smaller quantity was just fine. I have scores of Tamiya shades, plenty of useful colours, and my collection grows gradually. But I also have hundreds of enamels, the ubiquitous Humbrol range and Testor Model Master (which despite being superb quality, with an easy-stir jar and an enormous selection of specialty-matched shades, is getting hard to find in Australia, as Humbrol and Tamiya have grabbed the popularity).

I have not brush painted a model in 30 years, but today when I spray enamels I do so outside, which is a nuisance. Acrylics I can use indoors with simple ventilation, which makes them easy and convenient. But what about detail painting by brush? This is where the real applicability of the paints comes to the fore. Acrylics spray superbly but they don’t brush worth a damn--at least the Taniya variety. You can thin them a little and that helps, but the drying rate is like lightning and in one minute a brush is unusable -- clean it and start over. This seems a characteristic of the Tamiya range in particular, they are by far the most available here and I have sampled no others at this time (but I’ve heard others dry even faster…)

By comparison, dipping a fine brush in enamel paint provides familiar flow and control, and one can concentrate on the finesse of the task rather than fighting the characteristics of the medium. The same thing applies when airbrushing, though on a longer timescale. When used to the tip-drying characteristics of enamel, acrylics can bite you: you must keep the job moving when you’re working with the nontoxic paints, and when it’s done be sure you’re finished and clean the AB at once. This tends to lead to wasted paint, as when forgotten bits are noticed you need to mix more, and if using a syphon-bottle AB there is a minimum amount the airbrush will actually pick up from the jar. If working in enamels you have the extra working time to consider the job from all angles, turn the thing around again, look at it in different light, go 30 seconds or more and be sure the paint will still flow normally when you press the trigger.

My impression is that enamels and acrylics will continue to share the marketplace. Enamels flow on so smoothly they are a joy to use, they are a ‘friendlier’ medium than acrylics, you can polish their finish just like automotive paints (which ironically have all been acrylics for the last 25 years at least), and the range of precision-matched shades is enormous. The major manufacturers must have churned out over a billion bottles and tinlets in the last 40 years, in fact probably far more, Humbrol alone used to produce 25 million tinlets a year in the 1980s, if I remember correctly, and that’s an awful lot of paint in collections out there. I personally have tins that date from that era and the contents still slosh. But if acrylics were friendlier, dried slower, brushed better, and were available in hundreds more shades, precision-matched to historic sources, I would be using them more often. I have no wish to poison myself, and while the chemistry involved with acrylics is almost certainly not 100% harmless, it’s a significant improvement.
