Make Cambered Cauls with a Thumbtack

A cambered caul is a clamping aid used to clamp across wide surfaces you couldn't normally reach with clamps. The idea is definitely not a new one and has been around for hundreds, if not thousands of years. But they're very difficult to make as you really want a nice shape that will apply even pressure along an entire surface. There are some that swear by the jointer method of creating cauls, but in this video I show how it's not nearly as effective as using a simple thumbtack.
