I think Viesturs has a point about the sides being unconstrained in a twin-roller arrangement. The sides have the option of flapping like a drive belt. A combination roller/plain bearing might work, though, imagine a brass oval with rollers in the ends. There would be little load on the plain-bearing portions, but it would constrain the flex-spline. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
