I built a fixture to hold my stock securely while it was being machined. I started with two self-centering clamps that would allow me hold a stock of any dimensions so that it was in alignment with the side panels. I use a palm router with a guide bushing to trace out a pattern that I have made out of plywood. Here are some pics of my rig and the first test cut for the Anschutz rail made on a piece of scrap lumber.
