I think I know what you are saying. I have run out of diameter to the right of the casting mating face, but there might be room for a bolted flange inside the casting. it would probably make for a somewhat more straightforward assembly process too. If I did go for HTD pulleys as suggested by Steve then that section could be machined in one piece, and "spigotted" by the bearing outer. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ LogMeIn Rescue: Anywhere, Anytime Remote support for IT.
