Thomas Mann designed this bench pin with support optimization in mind. The cutouts in this unique bench pin allow you to slip the blade of your saw into the interiors of the pin arms in order to saw small parts with full support. The cutout at the v-point of the pin is for backing support of rods, wires, and sheet for filing. This pin is designed to be mounted to the top of your workbench giving you a flat continuous surface for sawing. Use coarse thread 1 1/4 inch drywall screws to mount. Made from Birch plywood.
