I spent the most formative portion of my engineering career as a sales engineer, interfacing between factories and customers (engineers and contractors). The impression formed initially has been reinforced through the years: Factory sometimes knows; Factory often does not. Factory will make up the stupidest s*** you've ever heard once you get them in deep. Blessed be their pointy little heads. I listen, but I reserve judgement. The bumblebee, not knowing his aerodynamic limits, flies anyway. Let's remember that glue, properly applied, provides strength that is orders of magnitude more than we need. Except on end grain!! :-)

March 2, 20197 yr I'm sure there are some limits. If adding a sprinkle of salt potentially reduces the strength by 10% that may not matter in most applications. But then some numskull might add a tablespoon of salt along 12" x 3/4" joint and things go south. (You know, if a little is good, more is mo' betta) And that guy's test (as he admits) is not very scientific. He tests cleavage on a few woods. What happens if it reduces shear strength by 60%?
