Amazing Miter Joint Clamp

Clamping up four mitered corners is tricky. You can buy specialty clamps for this, but why not make your own. Here’s how to do it.

1. Start with a long 1×4, as it’s easier (and safer) to clamp for making the angled cuts than a short piece.
2. Mark out the blocks, and then drill a 1-in. diameter hole in the center of each one. The hole prevents the blocks from getting glued to your project.
3. Cut 45-degree angles tangent to the hole, and then cut the blocks free from the long board.
