Into these holes the sharp steel points of the spur drive and live center insert and hold the piece steady and square. In addition to a center point the spur drive has four short blades arranged in a cross pattern that bite into the end grain of the work piece. Torque is transferred from the shaft in the head stock and the four spurs keep the blank spinning slip free once resistance is encountered from the cutting tools. The wood is so hard I had to use the Dremel to cut grooves to engage the spurs at the drive end. Once prepped in this manner the blank can be chucked up in the lathe and the fun begins. As the wood is worked down from square to round the cutting action becomes less violent and smooths out until a light but carefully controlled pressure is all that is needed. When a perfect cylinder shape is machined the wood turner uses different shaped gouges and chisels to carve the artistic details of the piece.
LeeAnn came out to my shop while I was turning and took a few action shots with her camera. She captured the magic well.
Magic is the right word. Here's a good project Mike-http://www.kipgen.com/radios/sale/coilwinder.htm
