The Dremel I have, the shaft is one piece from the back end of the armature to the collet and the bearings are solidly in the plastic housing BUT there's a long length from the front bearing to the collet. I had a Craftsman which had a short stub shaft with two ball bearings about 3/4" apart with one right behind the collet. A fairly decent flexible splined coupler connected that to the motor shaft. Unfortunately its vari-speed part took a $h!t and no replacement available. A more compact and perhaps easier to mount option would be a Foredom or similar handpiece. Even better, higher speed and likely better bearings would be a denture carving tool. I tried to snag a used one from a dentist office auction but other people were wiling to pay MUCH more than I. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ------------------------------------------------------------------------------ Go from Idea to Many App Stores Faster with Intel(R) XDK Give your users amazing mobile app experiences with Intel(R) XDK.
