Are Cauls necessary?
Some woodworkers recommend putting a slight convex curve on the clamping faces of the cauls. For this job, it may not be necessary. After all, no great force is being applied; you are only using the cauls to hold the boards flat, not bring them together.

What is a gluing caul?
Cauls are used when clamping a panel or a project for glue up. They provide pressure in places beyond the reach of standard clamps, or reduce the number of clamps required. The cauls also keep the panel flat during glue up and minimize the amount of work (and lost wood) to get it flat later.
How do you clamp the middle of a board?
