Hiya all, Thanks for the kind words, Mike & David. I thought you might like them. As you said, there's no shake now at high mags. + you can get the focus spot on.
The 'O' rings/drive belts are available from any Bearing supply Co. Cheaper by the 10 pack.
Mike, that installation looks great. Nice to have an engineer around at times. David, where are your pics?

Glad to be of help. Regards, L.
