Get a grip on corner blocks with a clamp block

When mounting corner blocks to reinforce a frame or case, use a clamp block on the outside to provide a flat surface for secure clamping and to prevent damage to parts. For example, to mount corner blocks on the table shown, make a clamp block with a notch from 3/4"-thick scrap. Then glue and clamp the corner block in place. Now drill the mounting holes. (We used a combination drill and countersink bit to do this.)
