Sure, these guys give you some clues:

I like the percussion version the best. One of the guys who bought some land here welded a rod to the outer rim of his tractor tire. He built a frame over the well with a pulley on it and ran a cable back to the rod on the tractor wheel. While his tractor was on blocks and the wheel was spinning it pulled the cable up and and down the hole. That motion of the spinning wheel ran the hammering action that drilled the well.
