|Norm's Tricks Of The Trade|
David: Michael Delmonico of Security, Colo. wants to how when he glues several boards together edge to edge, they tend to buckle. How do I make the panel stay flat?
Norm's Answer: There are two common reasons for edge-glued boards to buckle when being glued: Either you're tightening the clamps too much or the edges of the boards aren't perfectly square. If the boards still buckle after you take care of both those issues, try this trick: Alternate the clamps so that half are on one side of the panel and half are on thr other.
There's no need to protect a panel's edges fron the clamps" jaws-panels should be made oversize and then trimmed down. And while I don't worry about glue getting on the clamps, I do try to keep glue drips off my bench top by covering it with a piece of Homasote.
