The main part of the mechanism is basically a gear box from a cheap angle grinder. The crank and sprocket adapters are build it your self.

The router bit used in http://www.firechat.com/twistit2.jpg
was a 1/2 inch core box bit. I just used a couple different pitches to make the different designs. In photo http://www.firechat.com/twistit3.jpg
I used a rope bit from http://magnate.net/index.cfm?event=s...gory&theID=106
for the walnut rope shape and just a straitght bit for the long twist. I used a core box bit when making the stopper.

For the bottle stopper I cut out a template of the shape desired on the Shopsmith band saw. I removed the main head chain and ran the lathe and the router at the same time along the template to make the basic outline of the stopper. The main head chain was reinstalled and the template was used to controlled the Z axis path as the router was pulled along the X axis while making the spiral design. Six passes were needed to complete the spiral. The blank was first rounded by hand turning. Hand turning was also used to adjust the final shape at the base of the stopper.
