29mm motor - actual outer diameter?

It's thinking it is the 3/4" one they sell at home depot even. You need room for the sand paper.

I misplaced my set of "motor pokin' tools" which we called these Dowels when I traded my truck in for another in 2018. 'Cause if you get a motor stuck in the motor mount tube you need a motor pokin' tool to push it out from the other end; using a rubber mallet gently.

I think it may be closer to 1", since the inside diameter of that tube right now is about 28.5mm, which equates to 1.12". I think a 7/8" dowel would be just perfect to allow for the thickness of the sandpaper. I know I'll find something, as I have a Menards, Home Depot and Hobby Lobby right here in town. Thanks!

The sandpaper thickness will vary by grit and type. You might take calipers to the store with you.

machining a few thousandths off the outer diameter of the motor casing (possibly less safe?)

The case will not be able to handle the same pressure, and will be a research/experimental motor if you do that, which requires you to have an L2 cert to fly it.

Between sanding some on the inside of the motor tube and peeling off the label on the motor it should be doable.
