Re: How to attach an impeller to a CIM motor
I've seen elsewhere that teams have used a gear or pulley system to increase the RPM of the CIM. Don't know what type of impeller they were using, or whether that is an option for you.

If you have access to a lathe, you should probably be able to turn a little aluminum or steel collar for the CIM shaft. You could make it a press fit... but looking at what you've got there... you could probably just put a cotter pin through the whole thing (impeller, collar, CIM shaft) to hold it together.

If you don't have access to a lathe...hmmm... a bit tougher decision.
