It is really simple. Get a 12 volt drill with variable speed(old ones with burnt out motors are fine). Remove the motor, gearbox, chuck, etc. All you are left with is a handle with a switch and battery contacts. Wire your connector of choice to the output of the trigger (Where the motor used to be). That's it.


The advantage of this is you get the right voltage (assuming a 12 volt battery), variability in speed that is easy to control, and reversibility (without removing the wires.
