How to cut flat sided holes for Globe and Door motor

[ShadowKnight]

neither can the mabuchi motor (look in the FIRST guidelines and they highlight the globe and the mabuchi on this). Motors in general don't like side loads so I would be supporting all of your motors so that they do not experience this.

What we have done for both the Globe and Van Door motors in the past was this. Take a piece of steel shaft say 1/2 inch di. Face the end of it in a lathe and then drill a hole into the end of it that is just slightly larger than the di. of the round part on the end of the motor shaft. Then take the shaft and lay it in a vise on a mill. Tighten it snug but don't smash it. Then mill a slot right into the end of it. Slide it over your motor and use a shaft collar to clamp it on.
