Re: How to cut flat sided holes for Globe and Door motor

For the Power Sliding Door motor we have had very good success with an 11mm Trantorque.

They run about $30 from McMaster, but we love them. No changes to the motor (which is good if you burn one up and have to switch) and a simple hole (22.5mm if I recall) in the gear you want to attach to the motor.

As to the Double D on the Globe, I know some teams have modified a standard round broach to put in the flats. I THINK the Globe has a 3/8 round shaft with flats, so if you buy a 3/8 broach and grind in the flats, you should be all set. I have not done this myself, but have heard good reports.
