We just used a half inch variable speed reversable drill to power my dadant 6 frame extractor.
Removed the handle and plastic gear-had a sleeve made by a machinist friend that slides right down on the shaft with an allen screw to lock it on, the drill slides down onto the shaft that was machined and we made a mount to secure the drill on top. We added a router speed control from harbor freight to control the drill speed even though it is variable.
The biggest problem is spinning it too fast---take your time, no hurry.
"Younz" have a great day, I will.
