Dumb prop adapter / prop question


I want to use a 6x6 Graupner prop on a 3mm motor shaft, the prop appears to be listed as having an 8mm center hole.
Should I look for a prop adapter for a 3mm shaft with 8mm threaded hub (that doesn't seem to exist), so what is the right way to mount this prop..

Is this UK one any good, (you don't show what country you are in, but it may be available in others) - Aeronaut prop adapter for 3.0mm shaft, 8mm thread

I have used tape to build up the diameter of a standard prop adapter to suit the prop bore, works fine.

I wonder if you've finally found a use for some of the spare APC spacer rings that everyone has lying around?

Find some that are a tight fit on your prop adapter, spin it up and gently sand them until your prop fits. (or clamp several on with a nut and just sand the ones in the middle)
