Bax,

I recently purchased this spinner for an airplane that I am building.

The engine that I intend to use this with is a Saito Fa-125. The prop shaft on this engine has an M8 x 1.25 thread size. The adapter included with the spinner is threaded for a 5/16”-24 shaft. I have tried to locate an adapter that will work with this engine and spinner combination, but everything that I have found is threaded for a 10-32 retaining screw while the screw included with the spinner is 8-32. Can you recommend a source for an adapter that will accept an 8-32 screw and an M8-1.25 prop shaft?

Thanks for your help.

I think either of these two Tru-Turn adapters (8x1.25) will work fine.

Thanks for the links, but I have looked at those, in fact, I have a Tru-Turn adapter that was on the engine when I bought it used. Unfortunantly, The Tru-Turn adapters use a 10-32 retaining screw. The screw that comes with the spinner I have is 8-32. I have considered drilling out the hole in the spinner, but I'm not sure that there will be enought metal left around the screw head.

The Great Planes adaptors would have the 5/16" crankshaft threading. None have metric threads.
