I've been making some slow progress on the MAZ-537. I sort of got sidetracked with it addressing a slight issue that came up, but am more or less back to my main assembly process.
From the start, I intended to more or less build this thing put-of-box and place my emphasis on the weathering and base. One thing I did want to do was improve the look of the plain, flat cabin seats that came in the kit. I applied some Milliput to both parts and worked it to resemble seat cushions that had some actual texture and unevenness.
Here's where I got slightly off track for a couple of days. In test fitting the components I have assembled thus far to see how it all looks, I discovered one glaring issue with this kit: the rear of engine deck will be wide open with no engine inside, as Trumpeter doesn't include one. This leaves a big gaping hole.
My first thought was to just go out and buy a resin engine to drop in, but I really don't want to spend any money nor do I want to get my momentum on this thing interrupted waiting for parts to be delivered.
Besides, I just wanted something there to fill the empty space and I didn't care if it wasn't accurate. It will be barely seen behind the fuel tanks, so who cares if it's not really accurate. Well, someone might, but they'll just have to get over it.
Truth be told, I find myself all too often spending money on parts and such to solve modeling problems like this, rather than utilizing my skills, creativity and the stuff I have on hand. It's much more fun (and cheaper) to go the latter route, so that's what I decided on.
When thinking about this, the normally dim light bulb over my head suddenly came to life with a blinding flash. I remembered that among my multiple boxes of spare parts, I had an old HO scale diesel motor kit that I bought for a project in the early 90s. It's been kicking around ever since, still in the original package.
It looked about the right size for 1/35 and would fill the void of the engine deck nicely. Looking at some reference photos and what other have done in building this kit I realized I should also need to build some radiators.
Again, I'm not going for accuracy on any level here....just some noise to fill a dead space. An HO scale EMD 567 diesel would just have to suffice for a Soviet D12A-525. So, here's what I ended up with. I had to cut off two cylinders worth of the engine block to get it to fit, but that brings it down to an actual 12 cylinders. I added a couple of odd & ends from the spares box, some random brass rod and wiring made from solder.
I also build bulkhead for the rear of the cab, making some faux mounting bolts by cutting styrene rod on my NWSL Chopper.
The radiators started out as turret mounts from an old 1/72 Airfix B-29 that were build up with sheet styrene and brash mesh. I think they look the part well enough for me.
With the engine housing on and fuel tanks in place, you can barely see inside to know it's just cobbled together, but it sure beats having a big empty space.
