This is how I would try - caveat emptor!
First, drill a hole in the exact center of the 3x3 at both ends.
Scribe a circle around the center, and remove as much waste as you can
with the bandsaw. Build a support so that the wood sits like a
barbecue spit, suspended from the centers. Mount over a router table,
take very fine passes, spinning the wood....
If you can find one with all the pieces in good working order. Sears dumped
it a while back. Trend in the UK doesn't have it anymore. The Canwood is
gone. Entry level for such a device now appears to be a Legacy Ornamental
Mill for 1500 bucks and up. I understand that Router Magic
(Amazon.com product link shortened) has a
chapter detailing how to make such a thing from bicycle parts. I've seen a
site with plans for one but can't find it again.
