There are a lot of great CNC projects that use plywood. From plywood furniture to shop projects, plywood is a great medium for CNC machining. The challenges are plywood thickness varies all over the map and getting a good fit, particularly on plywood joints is tricky. I’ve found that making a precision plywood thickness gauge solves both problems.
Popular Woodworking Magazine just published my article on making the plywood thickness tester. If you can’t wait, I’ve posted the files in my download area and published a video on YouTube. The files are free. Just visit the free download area for access.
