Torque required for hammer to self right?

Yep, the drill motor had a sprocket on it with 8 teeth, and the axe had a sprocket with 40 teeth on it, connected to each other by a chain. So for every five rotations of the drill motor shaft/sprocket, the axe arm only rotated once, thus the 5:1 ratio. It reduces the speed but increases the torque (or turning force) so that it isn't as much of a struggle for the motor to turn the heavy arm.

Oh good, I guess there will be some modding to fit the small sprocket to the motor.
