Wood Joints

You can connect two pieces of wood in many ways. Here are some of them.

Glue (Leim 🇩🇪)

You glue two flat pieces of wood together. Use clamps.

You should glue long grain to long grain.

Good when you have a lot of shear force, but little tensile force.

Avoid screwing into end-grain. It will easily come out. You need to screw into long grain.

Countersinks are nice.

Einschraubmuffe: Man macht ein Loch ins holz, schraubt das Metallgewinde rein. Dann kann man eine Schraube sicher in das Metallgewinde schrauben.

Pocket screws have a flat hat that functions as a minature clamp.

Construction screws have a conical hat bores into the wood so that the screw sits flush.

Easy to assemble and disassemble.

Compressed piece of wood. You use a busikit to join two pieces of wood. You need a "slot" in the wood.

Good for small projects like picture frames

You drill a hole into both pieces of wood and put a dowel in it. Use a self-centering jig that clamps to the wood to get the holes straight.

Like a thick Busikit. You need a special machine to use it.
