Q: I used handscrews to laminate some boards together, but the joints didn’t come out tight. What went wrong?

A: Chances are that the clamp’s jaws weren’t perfectly parallel when you tightened them. If they’re not parallel, you don’t get sufficient pressure along the jaw’s full length. Properly adjusting handscrews can be tricky, but these two steps at right show a clever way to do it.
