But, even with 6 speeds, you are belt driven so there will be an unk amount of belt slippage. So if turning a spindle, the random slippage will probably trash any holes you try to to rigid tap. The bare minimum still needs a once per rev index pulse from the spindle. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
