Can anyone give me advice on how to keep a wheel free-spinning on a drive shaft.
I have machined a matched pair of wheels that will be functioning like a beveler and am using a bench grinder as the drive shaft. I have put a mounting plate on the bench grinder to hold guides for the beveler to feed bamboo into.
The problem I'm having is I am unaware how to "sandwich" the beveling wheels so that when starting the grinder, it doesn't automatically cause the wheels to tighten down on the wooden mounting plate and bind up. Because of the relatively short drive shaft of the grinder, the wooden mounting plate, and aluminum bevel wheels I do not have that much drive shaft to spare. Would fitting an axial bearing be a potential fix to allow the spinning beveler wheels to articulate freely when bound tightly to the mounting plate.
Any advice is greatly appreciated and welcomed.

Thanks,
