    I believe those are done with a powered cutter, like a ball, on a duplicating machine. Or the piece is fixed and the helix is cut by hand with a rasp. However, if it can be done on a spinning lathe, I would like to know how.

    You know I have a genius Son Jarrod and a helper from SA between the 2 they can figure it out.

    I believe low rpm and a good rasp could get it done, might need to start the groove by hand, but once started the rasp would follow the groove. I know I've seen it done, but may have to turn the lathe by hand to get it slow enough.

    Here's a video where the guy used a hand wheel attached...

    Google carving spirals. Essentially what Frank said. There are five parts to Stuart's videos. I didn't post them all, but you can follow on YouTube. He's enjoyable to watch and makes it look very easy.

    Dave, turning spirals in wood requires two timed movements. The turning of the lathe at a specific speed and a cutter (usually a router) moving on a horizontal axis. Here are some examples.

    The manufactured one (don't think it has been available now for years) was called a legacy lathe. http://legacywoodworking.com/ornamentalMilling.cfm



    I have a pen wizard which is somewhat the same as a legacy mill only in miniature form.


    Would think a metal lathe with a router for the cutter would do the job easiest. The difficult thing is the ability to keep reproducing the cut (so it can go deeper).

    I wish I had my new CNC machine.

    That entire table looks like a fun project.
