These are two jigs I use when making twelve sided segmented bowls. Pictures 1,2,3 show the table saw being used with the 12 sided segmented bowl segment cutting jig. It’s set at 15 deg to get the angles to work. The sled base is made of 3/4” birch ply, other woods are red oak or maple, just what I had at build time. Front and back pieces provide strength and a handle. Middle piece with clamps is the fence I cut from, and both clamps have wing nuts for quick adjustments. The last big piece on the sled is a blade guard to protect my sausage fingers while I clear the cut segments from the sled Pic 2 and 3 show this best with blade. I made the fence 7/4 thick to enable me to cut two identical bowls at the same time, or three depending on thickness of rows. Of course one at a time is fine too. I use a clamp to hold my length stop block for now.
Pic 4 shows my segment piece sanding sled I use with a 12” disk, 80 grit paper. This is a Malcolm Tibbets idea from one of his books. It sets the final segment length, final angle and cleans up the cut ends nicely.
Pic 5 shows the underside of the sled and its two runners as I don’t want any error due to sled wiggle. Screws are added to both runners to adjust as needed to keep wiggle to a minimum.
Last pic shows the options provided by such a tall fence for cutting one or two bowls at a time.
Thanks for looking.
