If you are lazy as me…  use your drill.

Update 30.10.25

Standalone drilladapter and upgraded parts can be found here.

Update 21.10.25

This version can be used if the drive gear and the handle are already glued together.  A standalone version will be released soon, with more upgraded parts like a balancer or mounts which can be attached to a ground plate.

M8 screw for for handle can be repuposed (different methods can be designed, just text me).

Attach the two parts with two M3x14 socket head screws (or longer ones) and two 3x5mm thread inserts. I could also add a hex nut version if you want.

I tightened a self locking hex nut on the handle and can use a 13mm socket on the drill.
