Thought it might make sense to go back & find the vid, so here it is -

I have heard someone say this before. Never have done it or tested this theory.

BUT, I ve been known to be wrong before.. Once, I think – probably back in 76.

- jerkylips

Wrong. It was ‘75.

I’ve seen this salt method used but never tried it. Supposed to prevent the slipping of the boards during glue ups. If used sparingly, it’s not supposed to affect the bond but I find that if I have a plan for the glue up, and do a dry run to make sure I know what needs to be done in advance, I can skip the salt trick.

I’ve tried it numerous times. The salt does NOT readily dissolve in the glue. If I were glueing up soft wood like pine, it did great because the granuals compressed into the wood when clamping. It created “teeth” to prevent slipping. Any hardwoods I tried, the glue up didn’t slip but I could pop apart the work with my hands after full cure. The granuals still remained (most of them) and created nothing but problems.

I’ve tried the “salt trick” with TB Original, TBII, TBIII, and Gorilla wood glue. Nothing dissolves the salt.

I use it from time to time, it does keep the parts from slipping around while clamping. It doesn’t take much.

Well, we use biscuits for alignment so I supposed using salt and other food makes some sense.

Good to know. I haven’t tried it yet either. I have
a Plano press now that makes flat glue-ups. I’ve
used wire nails with the heads clipped off before
and that works to prevent slippage as the clamps
are tightened. It’s more hassle than salt but if what
you say of hardwoods is true it may be the superior
approach compared to salt.

I had assumed the salt crystals would dissolve in
the PVA glue like salt does in water but now I see
how that could be a flawed assumption.

Absolutely! I have been using butter on my sliding dovetails for ages. Works like a charm.

On the other hand, milk paint has been around for ages and it still has its place.

It seems to me that anything you “sprinkle on” your glue up will only weaken the glue joint.
- jerkylips

Why do you think so? I’ve never done it and have no opinion, but I have considered trying it.

I’ve used salt a few times on glue-ups and it worked fine. Never had any issue with a “weaker” joint. The glue joint is still stronger than the wood.

I heard more commonly that you should clean the area before applying glue. Most tell you that it creates a weak bond. That’s a good one if it works.

I wonder if sand might be better than salt. Sodium and chlorine might interact

Nick Ferry over on you tube just did a quick video about this subject and an alternative way to keep boards better aligned. https://www.youtube.com/watch?v=Il5vFKGv3Uc

I though it was interesting.

Reminds me that back in the day, my Dad took a borrowed pickup truck to collect a 200lb block of ice. He told the ice man that he was concerned that it might slide around in the bed. The man took a shovel of gravel (from a pile right by for that purpose), threw it in the truck and set the ice on it. It didn’t move. Dad didn’t like it. He would have had a fit if somebody had done that to his truck.

Yeah, I could see that a little salt in the joint could help – but then again, I’d rather not do it.

I try to do glue ups with the lumber oversize so if it slips a little no matter.

Interestingly, this was the exact video I was watching, where he offhandedly mentioned the “salt method”.

Salt has a nice crystal shape with sharp edges, sand tends to be rounded from the process that created it.

A bunch of sharp cubes will prevent sliding better then a bunch of ball bearings 8^)
