I've got some tracks (plastic cog style) that I'm in the process of mounting on my minibike now. I've been thinking about making some spare cogs just in case. I can get a pack of thick plastic (nylon?) cutting boards for pretty cheap at Harbor Freight. Wonder if I cut a cog profile out of them...

I have this problem too. Didn't consider this when I bought the torque converter kit.

Thanks, @Charles S. The shaft connection to the cog (i.e. the pressed-in steel bushing) "torque sheared" into two pieces - one of which is still pressed into the cog. I think you're right, the bushings are molded in. The busted bushing looks like a screw now. No real access to weld back together...

Great blog/project! I love snow-peds! What kind of plastic are these type of drive sprockets? ABS?? I have a set just like it that I'm trying to reverse engineer. Also, is the bushing just pressed in?? If so, I can't imagine it can handle a lot of torque, right? Trying to think of a robust way...
