HI, that is my post with the Quad fence and Qwas dogs. For my table, I needed to keep the pivot point in the middle of the Quad track edge to align with the angle marks etched into the table and the indexing pin holes for the miter option to work properly. It was just the way I designed the angle system to work with the Qwas dogs and Quad track.
Without the miter complication, any dog system that holds the track in good alignment to the holes will work. The Qwas dogs work well for alignment because the shoulder on top of the dog has a good fit in the track channel. They do not hold the fence tight to the table though, so require some other method of doing that.
The Quad track with the ruler on the movable wooden piece works very well, and I use it in other applications. It makes it easy to calibrate the fence. One thing I have changed is I now glue a piece of laminate to the top edge of the wood, so the tape sticks better.
