Re: 8 mm motor shaft to .5 drive shaft adaptor

Perhaps something like this would work? A 1/2" to 5/16" flexible coupling:

Or find a steel bushing in the hardware drawer section of Lowes or a place like that. You may find one that will slip over the 8mm shaft and, with luck, will be about 1/2" outside. You might be able to split it and get it to clamp firmly in a straight 1/2" coupler (with enough Loctite).
