These next set of pictures show the basic kit that I can produce. Its of a “craftsman” nature, meaning that the faint of heart should not take a crack at it. It requires good modeling skills for drilling & tapping fastners, installing all the electronics and radio system (you have to acquire these yourself), modification to the tracks so they are durable, brass fabrication and soldering (if you chose to go the same route I did), and of course painting, detailing and weathering.
I hope these pictures post in the order I have written them up. If not, hope you can figure it out: Pix 1 shows all the basic parts for the project. Pix 2-4 is the Upper Hull casting and rubber mold I made (very heavy and took 3 lbs of RTV). Pix 5-6 is the template and resulting Lower Hull metal pan (only took 4 attempts to get this right…..

…..) Pix 7-9 are of the mounting bracket for the Gearbox and how it sets in the metal pan. And Pix 10 shows the cast pewter Return Roller assembly. I had intended to make the Drive Sprocket out of pewter as well, but was unable to come up with a crisp enough casting, so I changed over to a powdered aluminum/resin casting and that has worked just fine. You can see that result (gray color) in the first picture.
