Gluing up boards to make solid cabinet doors and table tops remains a necessary and time-consuming part of woodworking. And many woodworkers out there avoid glue-ups because of the machinery (or exhausting hand work) required to get a newly glued-up solid wood panel nice and flat. It takes a wide planer, wide sander, or unyielding enthusiasm for the joys of hand planing.

Make blocks out of solid 3/4″ material that resemble a 4″ long U shape. See below. Clamp up your panel with bar clamps or pipe clamps as you normally would. Then clamp U blocks so that they bridge over the joints, achieving two things:
In the end, you won’t need to do nearly as much planing and sanding to get the solid panel flat.
