Been plugging away with this one today. Let's just say this kit does not just fall together. But that's par for the course,for resin kits, from slightly misaligned parts to very poor instructions... the modeller needs to pay great attention as one progresses through the building.
Okay here are the words that go along with the pics
First of all here you can see I have laid out all the parts for the drive wheels. (#19) is the axle between the toothed outer wheel (#14) and the inner donut disc part (#16).
The instructions are not very clear but I figured out that the pins on the inner ring are meant to go against the smooth inner face of the spoked wheels. These are to represent bolts I suspect however they do not line up at all!
You can see in this example where I have superimposed the spoked wheel over the disc you can see that the alignment is somewhat challenged.
I could just go ahead and slam the parts together but this fact of mis-alignment just bothered me enough to make a change. So I was going to snip the posts off of 16 and replace with pieces cut from Evergreen rod. This did not satisfy my need for accuracy the ring parts also a wee bit warped and of uneven thickness.
This led me to score some of my own discs using some Evergreen plastic , pin vise with a pin and a circle template to which I glued some plastic rods. Then this assembly was placed againt some sand paper and sanded to the right depth to match the previous ring part profile.
using two part epoxy glue to attach the ring and toothed wheel I made sure the teeth lined up, using a spare track to test fit everything.
The drive chain needs to be very carefully trimmed off the pore blocks and cleaned up. These are fragile and I managed to break one. This was easily prepared but you can see this type of kit needs more work than your average plastic injection model.
the movement for this vehicle was supplied by two out rigged tractor systems on either side of the body. These are depicted by two solid slabs of resin that go together sandwiching the drive wheel and a smaller roller set of wheels between. These are pretty well done with major aligning provisions cast in place, with uneven results. In my case the upper surfaces lined up perfectly while the lower and inner surfaces of the cutaway areas not so much.
The bumps on the top here are useful for lining stuff up but are also the upper track rollers. You can see on the left one that is dry fit together the alignment issues. I will later on sand everything flat.
There are parts that only work for the right and left sides. The outer part has the nipple at the center.
