For rough work, I use a Wecher 25621/22, with a flexible shaft and two hand pieces. (the maller is show at top). http://www.wecheer.com/show_prd.php?id=320&lang=en For detail work, I use a PowerCarver I got from the Sculpting Studio. http://www.sculptingstudio.com/index.php?target=products&product_id=148. I used to use a TurboCarver, but it needed 2 rebuilds in a year, and they wouldn't let me purchase parts to do the rebuilds myself. I worked great ... when it worked. I've had NO problem with the PowerCarver. They take 1/16" high speed burrs, turn at 400,000rpm, and run off an air compressor. More speed = better control of detail!
