What size wheels are you using? Do you have any other gearing? What speed does this make the robot go?
We have thought about this, as it would elimate a lot of weight, as well as some of the problems with chain and sprockets. |
While your at Sears exchanging that busted ratchet for a free new one (<3 craftsman) pick up a breaker bar. When your putting a huge lever arm on a ratchet, you're really concentrating all that force on the little pin or ball inside that makes the **click-click-click** when you rotate the tool. To a point this is okay, but if you over do it you kill the ratchet. Breaker bars have no such parts and will not break quite so easily.
I have a 36" Craftsman 1/2" BB, and a can of
PB Blaster that *always* works
Good luck
