For a project that I will post shortly, I needed new tablesaw sleds to accurately cut the pieces. I decided to make the sleds using the Matchfit system. Initially, pieces were bought from MicroJig and then had my son 3d print more pieces including the wedge shaped pieces for the dovetail slots and the various knobs. I also tried using a plain dovetail router bit and straight bit to make the grooves in the sled. It all worked well.
I added some adjustments to the sled to better dial in the dimensions of the cut pieces. The sleds work very well and easy to setup to cut various angles.
