Coy,
Basically what I did was take a slower turning motor with higher torque and geared it high so I could get the same head speed. I'm not so sure this was the most efficient way of doing it. Next time I believe I'll go for the higher speed less torque motor and just drop the gearing.
BTW, by using the lower turning motor I screwed myself out of being able to use the belt drive because no one make the right cogged drive pulleys. [:@]
So lesson here is do what everyone else is doing and you will be able to use the same aftermarket parts.
