After buillding quite a few rods with a joe homeowner power wrapper and then dabbling with marbling finishes it was more than time to have a slip clutch on the dryer and the wrapper for improving my products. Below is a very simple clutch-chuck that was simple to build, and inexpensive as well. I wished I would have has it long ago! This is what prompts me to show others. It could be modified further but its a good start although not a pretty thing you would want with you plinth!

this is the finished unit. made from 1 1/2 pvc flat back caps, a 1/4 inch machine screw, a couple of fender washers each side. and a nyloc hex nut. for adjusting. the thumb screws were 1/4 x 1inch and 3 hex nuts were JB Welded in place after sandpapering the weld area. turning on the 8 rpm kept the epoxy from dripping. A round carbon fiber greased washer was placed between the flat back caps. simple and cheap is good sometimes!(http://i1344.photobucket.com/albums/p660/gst6814/041_zps67e63382.jpg) (http://s1344.photobucket.com/user/gst6814/media/041_zps67e63382.jpg.html)(http://i1344.photobucket.com/albums/p660/gst6814/036_zpsd66a89e2.jpg) (http://s1344.photobucket.com/user/gst6814/media/036_zpsd66a89e2.jpg.html)(http://i1344.photobucket.com/albums/p660/gst6814/035_zps7e2c12e5.jpg) (http://s1344.photobucket.com/user/gst6814/media/035_zps7e2c12e5.jpg.html) What was nice was that now you can stop the turn instantly, back up easily, and finishing the thread end under the base is now easier. I know it will rock for marbeling and appling top coats as well...........gst.
