Re: 8 mm motor shaft to .5 drive shaft adaptor
8mm is only about .0024 larger than 5/16". Get a 5/16" to 1/2" keyed adapter, and it'll be a tight press fit into the CIM shaft. If it doesn't fit at all, drill out the 5/16" side with a O drill (.316).

Use set screws or roll pins for the CIM motor side, unless you can find an imperial-to-metric key.
