Bigger update on Trumpeter’s 1:72 scale T-34/76 mod. 1942 today…
Front idler, road wheels, and rear drive sprocket have been installed. From the outside, they don’t look too bad…
…but a look at the underside prior to track assembly reveals my frustrations. The fit of the two parts making up each wheel was way too tight. We tried to make painting a little easier by priming and painting the wheels on the sprue, so denied ourselves the opportunity to make sure everything fit without arguments.
Indeed there were arguments, with spigots and penetrations requiring sanding and lubrication with polystyrene cemete so that they’d pass through each other. The result was some damage to paintwork which required some touchups
Working with rubber-band tracks is always a pain, and these were no exception. The ends were melted together using a lighter and a hot sculpting tool to create a continuous loop as the instructions directed, but they pulled tight between the drive sprocket and front idler rather than sagging over the road wheels.
German and American track tends to pull tighter, or are supported by return rollers, but you expect to see some sag with Russian track. Getting rubber-band track to act like gravity exists can be challenging. Overstretching the rubber would not be a good idea, as the rubber simply lacks the gravity of steel and could end up performing acts of levitation around the drive sprocket and idler that look even worse that if we just let the tracks pull tight from either end. Reseach suggested that superglue doesn’t work on Trumpeter’s rubber compound to glue or down, so I’ve poked a thin wire through preformed holes in the tracks and tied the upper track down to the road wheels either side of the drive sprocket and return roller. It’s not a perfect solution, but cheaper than buying aftermarket track that costs more than the original kit
While it’s definitely easier to paint track prior to installation, it’s arguably better to paint a flexible rubber track after installing. The paint won’t stretch or compress as well as the rubber as it’s manipulated over the wheels, so there’s a high likelihood that the paint will deform. We’ve brush-painted a Tamiya X-10 Gun Metal to start with, which will provide a dark metallic colour finish. This looks a little shiny right now, but washes and weathering to follow will tone that down…
We’ve touched up the axles damaged by the fit issues with our darker 4BO blend. This has turned out a little lighter than the original, but does create an interesting colour variation that doesn’t look too out of place
Next steps will be picking out a few more details and highlights of raised edges before proceeding to clear coat to seal it all in…
