For this new Spline Cutting Jig I used a double track system for the two adjustable supports so they can move freely over the angled surface while keeping firmly connected to the jig. A build-on stop with hidden rubber pads fix them in any position. I could ofcourse use a single T-track for this jig but liked to do the experiment.
A kerf at the bottom of the angled surface creates an extra clearence.
Its relative heave weigth helps to keep the jig secure on the saw table and dampens any vibrations for a smove action over the blade. Its works like a champ.
