This project will use old arctic cat parts to evolve into a personal tracked mover..
The drive gears are made of 1" nylatron plastic. A very strong material with a lubricant impregnated into it. Here is the blank : 8 inches in diameter.
Using a 1" wood drill bit and hack saw and a belt sander I formed the main drive gear. Several hours of work and viola a gear.
The Track was split down the middle. Using a zip cut disk and lots of time I was able to produce two mirrored tracks.
