Mark, I have an extra RX8 trigger wheel
and my next door hangar neighbor is making a hub
for it as we speak.

I will try to find a better motor as the shaft
diameter on that one is a bit marginal IMHO.

Paul,

How about using an air grinder?

Mark

That would work. I checked mine and it goes to 22,000 RPM.
The question is.... how to you control the speed?
