Just finished making some handles for the mill. I have dual shaft steppers on my mill. I find the need to use the mill sometimes manually as its much quicker for me to set up. The handles can go on very quickly and are very nice to use. The brass handle rotates around a steel pin that screws into the aluminium part.

The reason they look so complex is because I messed up I first made them so that there would be a 'friction' type grip by clamping the brass onto the motor shaft.......but the brass isn't a very flexible material to work with - once it does bend it doesn't bend back!!!. So therefore I made a different method of clamping. I drilled and tapped holes and screwed down machine screws onto the motors shaft. It seems to be a good solid clamp and doesn't mark the shaft too much.
