Question

How to mount a 4mm prop on a 3mm shaft?


I would like to adapt a boat prop (probably a Gaupner 40mm diameter intended for a 4mm shaft) to an aircraft 3mm shaft, any suggestions on an easy / cheap way to do this? I was thinking along the lines of a very thin brass shim, but I don't know where I might find .5mm thick brass cheaply/easily. Any other ideas?

No, the shaft of the motor is 3mm and all the props I've found are for 4mm shafts and I want to mount the boat prop directly on the motor's shaft (or use as short an adapter as possible, this is going to be used in an ROV project BTW).

Shaft adapters


Try www.wmberg.com
in their on line catalog/products click on couplings then shaft adapters,choose metric first then under"type" choose shaft adapter the pdf file shows an adapter with a female 3.0mm i.d. and 4.0 male or o.d with a 11.0mm length stock 3SAM-10 If you don't go to the pdf file it shows 3mm X 3mm I don't know why. Is this what you need? It will also need clamps. they got them too. Good helpful people, products a little pricey not too bad.

Thanks, that's a great resource. You wouldn't happen to know where I can get plastic Graupner 3 or 4 blade 60mm props for a straight (no thread) shaft, would you? I used them in another project and would like to use them again in this one (so the parts would be compatible) but can't find them anywhere.
