New jig, who dis?

My second time building Michael Alm's Picture Frame Jig. The old one had quite a few issues. Primarily that I used a piece of pine for the runner that started out loose and has progressed to sloppy and almost ruined my last frame with gappy miters. Used maple this time and probably got to snug of a fit to be honest, but I also added a countersunk screw and washer to prevent the sled from tipping when it's pulled back. Tested it out making a test frame from some leftover frame stock, oak sandwiching padauk.
