MiniArt T-44 part.6 Finished at last

Well, this has been a journey.

As a last step (well, series of steps) I added mud and dust to the tank. I did not want to make it look extremely muddy -probably not very realistic, and certainly not very appealing to the eyes. (Well, it’s a personal opinion.)

The other reason is that I’m not good with mud. I know. It’s horrible, but there you go: as far as mud goes I’m a noobie.

I’ll detail the process of mud-making, but unfortunately I have not made photos of the stages.

As a first step I mixed up earth colored pigments (from a railway model supply company), static grass and plaster in equal amounts. I added some water, and used this mixture  on the wheels, the mudguards, and the lower part of the chassis.

(Instead of water you can use white spirit, enamel thinner or even earth colored enamel/acrylic paints, or other products. I think. I’ll experiment with these.) I also used the thinner part of this mixture to create splashes on top and on the side of the chassis.

All looked well until it dried… due to the plaster the color shifted to a much lighter complexion. (You can see it on the photos that show the splashes near the driver’s hatch.)

Well, I did not get a heart attack despite of this; the review for Armorama was finished, so I was free to experiment.

I took a stiff brush, and started rubbing some of the mud mixture off on the sloping front and on the back; it made it look like it was washed off over time. So far so good.

The color issue I solved with burned umber washes (this color is the best friend of every model builder…). I dabbed a loaded brush on the lower parts, and let the capillary action draw the paint upwards. Repeated a couple of times, and the results are not half bad: the top is still faded, light color, representing very dry mud; while it gets darker to the bottom, representing the still wet, fresher mud. The fact that the wash and the original mud application left some “tide marks” actually works in my favor now -it looks pretty damn authentic. Real mud leaves these marks as it dries, too. I successfully turned a lemon into lemonade I think. (The application was more of an experimental one -let’s see if it works- rather than a conscientious application of skills…)

I did the same with the wheels. The static grass gives a nice volume, and some hint for vegetation caught up in the mud; I have to say I’m pleased how it turned out, and feel pretty silly for not using this before. (I bought the static grass back in the US in 2008… It spent some time in my mother’s attic since then, but still. It is a very useful addition for any modeller’s toolset.)

The exhaust was treated with rust colored pigments mixed in enamel thinner. Once it tried different dark washes were added: simply loaded the brush and dabbed it onto the surface at random. The capillary action did the rest, creatinga nice-looking rusted look.

I’ve used light brown pigments on top of the turret and the chassis both dry (just dabbed on with a brush), and mixed with enamel thinner. In this case I used a clean brush to carefully blend in the spots. Some remained a tad darker -as if it was still wet a bit. The reasons I’m not sure about yet, but it does kind of look good, so I’ll take it. Again: the result of a happy accident. (Perhaps I should have said it was pure skill… next time.)

Parts of the tank were rubbed with dark steel pigment giving them a metallic shine. zyr6yyreszhgqr

For oil and fuel stains I used AK Interactive’s engine oil and fuel stain products. (I try to mix most of my stuff, but some are really useful.) First I created a very diluted solution, and made larger spots. Once dry I used a less diluted solution in the middle.This, with the dust layer underneath makes it look pretty good I think. (Second try on these products; and the first try I diluted them… The first try was not as convincing.)

Oh, the engine. Let’s not forget about the engine. I’m planning to display it just as I did with the T-34/85 – in front of the tank.

The engine block received the same bluish base color as the interior (I’m fairly certain the engine was bare metal, but I liked the color). The top was painted anthracite, and was rubbed with dark steel pigment -it gave it a nice, metallic sheen. (The same effect can be achieved with ground up graphite.)

The exhaust pipes were first painted with anthracite, same as the engineblock’s top. I mixed rust colored pigments with enamel thinner, and used this mixture to add a basic rust color and some texture to them. I’ve used soldering wire for the wiring. I’ve seen some amazing works which shows the ignition wires yellow, but watching this video of an ISU-152 I think it’s safe to go with silver.wwpg9nr

Well, here it is. The deed is done. I need to attach the antenna, and mount it in a display box. Just in time for the MiniArt SU-122 with complete interior and the T-44M I’m reviewing… Keep tuned in; I have several interesting models from MiniArt and OKB to review.

Consideration of your (and others’) health in model building

I thought about writing up a short summary of the potential dangers lurking in our hobby as I’m not sure all of them are widely known. Let’s hope it’s something of use for everyone.

So here it goes.

Sharps
Well, that’s a no-brainer. We cut with scalpels, saws and other sharp instruments. Common sense (and really sharp blades) are a must. Seriously: don’t try to work with a dull scalpel; it’s more dangerous than a sharp one.

Resin dust
Well, if we’re at the cutting stage… Resin is dangerous. I’m not kidding. It’s toxic when in liquid form (the fumes and the resin itself), so keep this in mind if you DO work with liquid resin, but you can basically eat it once solidified. However, cutting resin with a fine saw, or sanding it releases very fine dust. And this fine dust is a carcinogen -in other words, it’ll increase your chances of developing (mainly) lung cancer. It also stays airborne for a long-long time, giving a chance for everyone sharing the room with you to enjoy the health effects.
You should either wear a mask and work in a fume hood when your are producing resin dust, or, a simpler -and safer- solution is simply to use wet sawing/wet sanding techniques. In practice it means you should be working with resin under running water (or a constantly wetted saw/drill/sandpaper), so that the dust is immediately absorbed. This way you are not endangering yourself or your loved ones. (This is a thing to keep in mind for any activities that create fine dust- even carpentry. If you sand your model, use wet sanding techniques, period.)

Dangerous chemicals: glues, paints and fumes
Well, yeah. A lot of the stuff we use have organic solvents. Adhesives, paints, glues… and organic solvents, such as turpentine, white spirit, benzene (I believe this one is not in any of our stuff, though), toluene, etc. are NOT good for you. At all.
When you use glue, have proper ventilation. You can also use special glues that are less toxic, such as Tamiya’s Limonene. Sometimes you can consider using simple white glue; surprisingly, it can have multiple uses. As a turpentine/white spirit alternative you can get ZestIt, which is a much more gentle alternative. (I’m trying to avoid doing product endorsements, but in these cases I did not find any other alternatives.)
Superglue is a separate issue altogether. It was used to glue wounds together on the field in Vietnam, until the injured could be evacuated to proper medical facilities, so no surprise here that it’s perfectly capable of gluing fingers together. Pulling will only tear the skin off – use debonder, or acetone to release your fingers. The fumes of the glue are not very safe to inhale either, so, again- ventilation. (The fumes are also perfectly capable of “frosting” any clear parts or finished paintwork, so ventilation is also quite important to avoid ruining the model if you add parts after the painting phase.

Painting… there are several types used in modelling, as we know. I will not go into all the different types; there are several detailed explanations online what paints are available for an average modeller. Just a short (and somewhat incorrect) introduction from the point of health and safety. The so-called enamel paints have nasty organic solvents, but have better properties; many people prefer to use these for their work. The solvents used in acrylic ones are less dangerous but you make trade-offs with the durability and coverage. (Personally I don’t use enamels at all.) When you brush any model paints, ventilation is, again, a must.

Solvents are only one side of the equation, though. Airbrushing paint creates small particles of paint in the air… and as we know, small airborne particles are not good for you. When you use your airbrush, it is imperative that you either are in a very, very well ventilated area (such as outside of your house – I sometimes paint on the patio), or, better yet, you use a spray booth. I cannot stress this part enough: if you use an airbrush, get yourself a paint booth. You can either buy one (the price ranges from expensive to very, very, very expensive), or you can make one using stuff you can get from any DIY store.
If you go with the buying option, there are affordable, folding versions available; I can wholeheartedly recommend those. (They save on space, if you don’t live in a mansion.)

If you make one, just get a large plastic box, a brushless fume extractor (this can be important, as organic fumes and electric sparks are not very good together), some HePa filters, and ducting – even with mediocre skills one can build a pretty functional fume hood. I went this way when I was in Florida, but had to leave it behind when I moved across the ocean. It cost about 50 dollars altogether, and took about 3 hours to construct. (Test it with a scented candle or something of that sort: if the smell/scent does not come out of the hood, you’re fine.)
