Clamping up four mitered corners is tricky. You can buy specialty clamps for this, but I make my own. Here’s how to do it. Start with a long 1×4, as it’s easier (and safer) to clamp for making the angled cuts than a short piece. 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. Cut 45-degree angles tangent to the hole, and then cut the blocks free from the long board. We’ll walk you through how to make one for your home shop.
Pocket screws create a solid, simple-to-make joint. Because of the size and visibility of the hole, it’s usually located in areas that are concealed or rarely seen (though special plugs can be used to fill the holes.) Craig Sommerfeld, founder of The Kreg Tool Company, is credited with popularizing pocket screw joinery in the 1980s. The company today is the leader in creating the jigs, clamps and screws used to create pocket screw joints. Learn how to use a pocket screw jig in woodworking projects.
