2" Extension for a US41 engine

My Feedback: (6)

Are you speaking of a propeller hub extension, or what? These are the only guys that have anything for US engines that I know of; anything else would probably have to be custom made.

Yes, if he is speaking of a prop hub/shaft extension, that was my thought as well; 2" is quite a lot.
Hardwood dowels, (round or square), from the hardware store can make good mounting spacers. On engines that do not normally mount on spacers, I sometimes make spacers out of plywood. I trace the mounting surface onto the plywood, and cut it out with a jigsaw. I then use a large hole saw to cut out the center area to save weight.

I am building a Vailly L-5 and I was trying to locate the extension that Roy suggested. He no longer sells them, and Ziroli does not make them and they suggested I check with Sierra. I have sent them several emails with no return so I will just sit and see what I can come up with.
