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.
Flux Brush Applicators
Keep a few plumber’s flux brushes ready for spreading glue on your projects. You can get the brushes in the plumbing department at home centers. (Or buy 12 glue brushes, part No. 875233, for about $4 from Woodworker’s Supply. They’re perfect for brushing on just the right thickness of glue. Bend the handles into U-shapes so you can hang the brushes on the edge of a jar half-filled with water to keep them from drying out. No cleaning needed. Just wipe off the excess water with a paper towel before use. Thanks to furniture maker Bruce Kieffer for brushing us up on this great gluing technique.
Cinching that’s a Cinch
Octagonal, hexagonal and even square pedestal bases for tables can be aligned perfectly for gluing with heavy-duty plastic sealing tape. Cut your bevels on the workpiece edge and lay them with the inside face down and one end butted to a straightedge. Align the bevels so they touch along their entire length and tape them securely. Next, carefully flip them over and apply glue to the joints. Then stand them up, fold them together, tape the final joint and pull the shape together with belt clamps.
