I thought I'd try to cut a spiral something like Steve does so very well. His website shows some very impressive work.
Of course, I was free-handing the cut but did get a spiral of sorts. I made the spiral 1" per turn as shown on the video and tilted the table to 20 degrees and started cutting. The result was a spiral, I think - I couldn't get it apart.
If I could feed the dowel into the blade at a constant rate, it probably would have worked out better.
Not sure how to make a feeder, Steve mentioned a motor drive.
The other problem is working out the starting point of the cut. I think with a little more thought, I might be able to get a single spiral to work but the double he shows on the spreadsheet would be difficult.
If a person is serious about cutting spirals, the best course would be to buy the spreadsheet and instructions from Steve. But, now that I have said that, someone on the forum will show the spiral they made using the hints in the video.
