I just finished building a modified Paulk workbench, sized at 32" x 72" for a basement shop. I used 3/4" BB ply for the top and bottom and 1/2" ply for the ribs. The holes are 20mm with 96mm spacing, bored with the OF1400 and indexed track. The bench can be flipped over and the bottom side has no holes and can be used as an assembly table when you don't want to get glue squeeze out in the dog holes.
I also finished a modified Paulk miter stand for the Kapex for fixed use in a shop, sized 24" x 72" with 80/20 extension rails. I did not like the Paulk design with the 3-1/2" plywood ribs running the length of the miter saw stand, effectively blocking usage of the cubbyholes for storage in the stand. Instead, for rigidity and support I used 1" square thick wall (0.125") steel tubing as rails, and tapped and threaded them for attachment to the plywood. The steel rails sit inside the bench but are lower than the oval openings in the bench, so they don't interfere with tool storage in the bench. I saw no need to bore 20mm holes in the stationary top and instead I dadoed the top for Incra track that is used for the rail extensions and the Festool clamps.
Here are a few finished photos below.
