Built a large 4x8 assembly bench with t-tracks. Specifically to hold jigs in place like my K4 Master set. This enables me to work on very large projects. I can easily handle big stock like a 2x8 sheet of 3/4 furniture grade ply. Which is something I do often. Here I've got the table configured to handle a box jig and the K4 in the 4" wide configuration.
