I'm using a 1/2 inch thick threaded axle for my battery buggy and I had a hard time finding spur gears that work with my pinion gear for my motor. Also, the pitch of the spur gear and pinion gear must be the same to work, right? If anyone knows a good website for gears, please share it.

I'm new to Battery Buggy, so I was wondering if someone could post a picture of a battery buggy because I don't really understand how the parts work with each other. I would deeply appreciate if someone could post the link of a picture or something like that.

This is my first year doing Battery Buggy or Electric Vehicle, so I was wondering how do you use a DC motor to rotate my threaded axle?
