This may sound dumb, however I understand that when you glue up pieces of wood (mainly small pieces) and they slide around easily during clamping that you more than likely have to much glue on the joint. I'm really curious though, I read somewhere that if you sprinkle salt on the glue joint that it will help keep the 2 pieces from sliding?!!! Can anyone tell me if this really works and if so what are the long term effects? I know salt is corrosive to metal so I am wondering if it has some kind of long term effect on wood.
