The pack of clevis pins I bought came with a few extra, so I drilled a hole in a small block of 3/4 ply and mounted it under the cutting area to help with loading plywood onto the vertical frame. Also drilled a hole in the 2x4 near by to store them once the workpiece is mounted. Sharing in case it helps anyone else out!
(don’t mind the wonky cuts, still getting the Maslow tuned up.)
