I took a 1x10 board and drilled 20 holes, 10 on each side, and installed bolts to act as legs that can be adjusted. The board turned out to be more warped than I though, so I weighted it down with 5 concrete bricks. I then laid down the lines for each jig at the prescribed distance and used a laser to lay down a line for the WL mark. I started to add the 1st jig.
