This video is about making a table saw Taper Jig for the Ridgid R4512 table saw commonly available at Home Depot, and for other table saws.
I chose to make this one from the Woodsmith ‘Shop Notes’ magazine as it offered more features for doing tapers.
I already had most the materials. If I had to buy them all, then you may be approaching the cost of the one from Rockler. But as woodworkers, if we want it better, and as a part of the craft and joy, is in making your own jigs.
