I've got 2 mills and will eventually build a power drawbar for the 2nd (CNC'd) mill that is integrated with the belt drive components. Meanwhile, food for thought: Guts of a Kurt power drawbar are built on a Chicago Pneumatic butterfly impact wrench.

I've wondered about a permanent electric version by gutting an e-wrench, hook up DC power, remote switch etc. But still have to solve how to disengage during long stretches of mill running, either mechanically or electrically.
