Thanks for the previous answer. I just now came across it. I guess that the response was not tied to my email.
Another question for you please. Both pulleys that you use look like they are meant for a 1/2" shaft. The GP460 has a 3/4" shaft. Did you machine it down? The parts for the pulleys would state the size as ShaftLoc/Bore .75/.5.
Can you tell me where the bendix and its container came from? Tom Milton's bendix drives appear to be quite different. Did you make the container and the mounts? I am looking to get something clean like yours.
Alan, I have been reading your post on the goped prerotor which I wold like to build. Can you tell me the belt size and the pulley size that you are using and at the top I know that you are using a chevy flex plate but what year is it. Also the unit at the top I know has to have a gear to match the ring gear but what else is it. Is it some kind of starter unit? Thank you for all the info and you have a very nice looking gyro.
