I had a Plano press 20 years ago and it was okay, but I wouldn’t spend the money on another one. Has anyone come up with a decent DIY solution for panel glue-ups? I have plenty of Bessey circa “Made in West Germany” clamps but I have destroyed them to the point they aren’t exactly efficient anymore if you can believe it. And even if they were I need to process more than a dozen panels a day. I need a solution for a glue press to pump out a couple hundred cabinets-sized door panels in a week – any ideas?

Curved cauls are far superior to the Plano press. Easy and quick to make and uses your existing set of clamps. Been using this technique for 40 years with perfect success every time.

Rick would you care to show use some? I have made and used them on a limited basis. How did you determine the degree of arc you incorporated in them relative to their length? What l x w x t do you prefer? What species do you prefer? What do you use to prevent squeeze-out from bonding with the cauls (I used wax paper but it would be cumbersome on a large scale)?

There’s no one right way to make them. Tape or wax to keep the glue from sticking. 2×4’s work fine. I do like to make sure they are all exactly the same for consistency. I typically mill my cauls to the same size. One way to determine the curve is to put an 1/8” spacer under the middle of a caul under the middle of a caul and clamp the ends down and scribe a line across the length. When you release the clamps you then plane or sand to the line and you will have your arc. I usually use a mster one and use a pattern bit on the rest of the cauls. I only use pipe or bar clamps and F clamps when gluing panels. Some people like to use carriage bolts to squeeze the cauls together but I fing that too slow and inefficient. I can glue up a 4×8 panel by myself very quickly. I even came up with a way to mount them like a Plano on the wall but never got around to doing that. The reason the Plano isn’t that good is because it lacks the curve. My friend had a Plano and my panels always came out perfect and his were always inconsistent.
