This is my new fully adjustable table saw sled for cutting segments for making segmented bowls. The sled can be adjusted to almost any angle between 90 and 45 degrees. For the pictures, I have it adjusted for cutting 15 degree angles on both sides of the work piece for a total of 12 segment pieces to make one ring.
The sled is made from a 2’ x 2’ x ¾” Apple plywood. I chose ¾” over ½” this time because I wanted to make sure the sled remains flat and stable. I had a simple version of this sled before that was ½” Baltic birch and over time it slightly bowed. To keep the sled from advancing too far over the blade and cutting a kerf completely all the way through the sled, I use a stop block in the miter slot of my out feed table. The runners are made from UHMW material and the sled glides quite nicely on the table saw top. The adjustable fence and smaller stop are made from Oak hardwood. The sled’s front fence is a made from a scrap piece of ash hardwood I had left over from another project. I used 5/16” T-bolts and the slots cut in the sled are 3/8” to allow a 1/16” play and for fine angle adjustments and 3 each 5/16” T-knobs.
I use a digital protractor to make the fine angle adjustments. This sled is not my original design. I took the design from a segmented wood turning book and instead of using t-tracks for the fence hold downs I decided to cut slots for t-bolts instead for strength.
I cut walnut and oak segments (pictured) then put them all together for an almost perfect ring (final sanding of each half will fix being off by about 0.10 of a degree). Since the sled is fully adjustable you can also use it for 90 and 45 (and anything in between) cuts. I still need to figure out some sort of hold down method for safely securing the work piece when it gets very short.
