Well if I had a real table saw a sled would be great. What I have now are two Shopsmiths one is a 1957'ish 10ER the other is a 1978 Shopsmith. They don't really have room for sleds. Someday I hope to sell one or both Shopsmiths and get a real table saw router table and lathe.
A table saw sled with an adjustable angle fence and a toggle clamp is much safer and faster. The Bessey auto adjust toggle clamps are great. i have also used a pencil eraser on a new unsharpened pencil to hold small parts against a stop when making repeated cuts.
I put this together without aid of jigs etc... Next time I will spend more time and probably cut small segments by hand! small segment cuts on a 12 inch miter saw are very scary! The 2 segmented rows are done so it is all end grain.
