To follow a circular path the machine has to accellerate, and the magnitude of the accel is v^2/r To make a 1" radius circle at 400ipm the machine has to accelerate at 44 in/s/s. Which is less. Unless I am making a mistake (I am not used to working in inches, but I don't think that matters here?) So, it looks like that is not the limit here (I am almost certain that _was_ the limit in the example that Steve Blackmore showed us a few months ago) -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
