Sprinkling salt during glue up - woodworkersteve - 07-22-2017
Didn't want to hijack the bent lamination post, but thought about the solution I saw during an episode on "A Craftsman Legacy," where the plane maker sprinkled salt over his glue to prevent creep. I've never heard of this or seen it mentioned on here, but of course, I'm a "hack."

Use salt or grains of sand.
Not too much, of course.

For years I have used fine sand, being careful not to put it where I would be cutting. I don't know if salt would affect the bond with PVA glues. With sand it only takes a few grains here and their.

no thank you I will pass on both.
shrink wrap and maybe a well placed brad or two that can be removed put in the lamination are faster and simpler
The thing missed in the lamination thread was oversizing to allow for slippage.

Wouldn't salt rather quickly dissolve in glue?
I have used sand a couple of times, just to see how it worked.

It's for the mechanical action, not chemical. The sharp crystals slow the slide under pressure before they become part of the glue line. As mentioned, sand, fine sawdust are also used, but they squish under pressure, not dissolve.

Use grains of salt or sand of the right size. I press the mating boards together slightly by hand before clamping them to avoid any creeping. This is the simplest way I have known and used to clamp two pieces face to face with the least hassle. Of course, you can also do it the usual but less efficient way: glue two boards and trim off the edge(s).

Although I've never done this technique, it's good to hear that it wasn't so far out in left field!
