If you want to laminate boards to make a tabletop, you'll need a wood jointer. It's also handy for flattening warped, rough-sawn or reclaimed lumber.

Jointers are expensive, and they take up a lot of space. But there are two ways to joint wood without a jointer, including making your own jointer sled.

If your workshop doesn't have a jointer to square up an edge or your wood piece is too large to fit through, you can use your planer to flatten both pieces of wood.
