Meet the pro
In 30 years as a professional woodworker, Dave Munkittrick has tried just about every clamping technique imaginable. Some of them are his own inventions; some are borrowed from other woodworkers. As for the rest, he's been doing them for so long that he can't remember where they came from.
Dave says, 'Over the decades, I have amassed a huge collection of clamps—every size and type. But the arsenal of clamps in my shop is no more valuable than the arsenal of clamping tricks I carry around in my head. So even if you're a beginning woodworker with a modest clamp collection, these tips are for you. I'll show you how to clamp to get the most from the clamps you have and even a few ways to clamp without clamps.'
Cauls Keep Glue-Ups Flat and Flush
My favorite cauls are made from 2x4s. I carefully select ones that have a slight bend or 'crown' along the 1-1/2-in. edge, but no twist or warp. The crown is an advantage because it creates extra pressure in the middle of the caul. I label all my cauls with an arrow marking the direction of the crown and the length of the caul.
What's a caul?
If it's designed to spread clamping pressure over a wide area, you can call it a caul.
