I build the biggest file testing machine using my shaper in order to perform tens of thousands of perfect strokes as I put files to the test. After receiving a lot of spiteful comments for back-dragging my file, I decided to look into why it is frowned upon. That journey led me to create my very own file tester rig. I use the waterjet, go kart grinder, and Marvel bandsaw in order to fabricate a device to attach to my shaper, ensuring I can test files!
