12Taming edge-to-edge joints
Oftentimes it seems like edge gluing gives the boards a mind of their own. They slip and slide out of alignment leaving panels with ridges that are a nuisance to flatten out. To help tame my boards as I clamp them together, I made a set of C-shaped cauls from
1-3/4 × 4" lengths of straight stock with a 3/4 × 1-3/4" notch cut in each piece. To use them, clamp opposing pairs over the joints at both ends of a glue-up as shown. The “feet” on each pair of cauls will keep the surfaces aligned while the notches avoid any glue squeeze-out.
