I’m an old Marine and—more often than I like—I make flag display boxes for the families of fallen comrades. The triangular boxes are finicky to clamp up, so I devised a brilliant (for me) but simple solution. Beginning with three 3" long pieces of scrap 4×4, I bandsawed a 90° notch into one and a 45° notch into each of the others. Then I drilled a small relief hole at the apex of the notches and cut a shallow dado on the back to locate a clamp strap. Voila! The cauls pull the box walls together tightly, spreading clamping pressure across the joint, which also eliminates the need for multiple band clamps.
