Jimmy Rocker demonstrated how he finish turns the exquisite platters he brings to "show and tell". At Jimmy's previous demo, he rougturned some platter blanks and then allowed them to dry. At this session he demonstrated his reasons for cutting a round mortise in the bottom and then dovetailing it. In this way, he can use expansion chucks to hold the workpiece to the jaws. He also demonstrated alternatives to that process with the use of double stick tape and sacrificial glue blocks.
