This 1/4” plywood veneer cutting board is backed with 22 gauge steel. Using this configuration with a straight edge and Magswitches aids in holding and stabilizing one or more pieces of veneer with the straight edge.
The photo above shows the cutting board in use with the white melamine straight edge. Hardwood would be a better choice of materials for a straight edge (this was scrape). The straight edge used is 40” long and 4” wide with five 40mm holes for Magswitches. I recommend creating several other sizes of straight edges to handle your cutting requirements. The two smaller straight edges I have are 10” and 24” long.
The bottom of each straight edge is covered with 120 grit sandpaper to reduce movement.
The steel sheet can be seen in the photos above. The two surfaces were glued together with spray adhesive to form a temporary bond. Should the cutting surface wear out it can be easily replaced.
The board is also great for clamping the veneer with the edge overhanging one of the sides. This is handy for sanding the edge flat. I use a 24”x2”x2” piece of aluminum tubing with 220 sandpaper glued to one side to sand the edges.
