You probably only need a tiny thickness round the circumference of a NEMA34 to handle the torque. I suspect 0.2mm would be fine for torsion. There is even an argument that having the mounting compliant in the "wobble" directions is good to give the bearings an easier life. (You quite often see industrial drives that hang on the shaft they are driving and then just have a ball-jointed arm to take the torque.) What you decidedly don't want is any resonant modes in the operating speed range. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Learn the latest--Visual Studio 2012, SharePoint 2013, SQL 2012, more!
