Mywood

I have used tite bond 50 and slowset for quite a few years.The technicians at franklin International and Helmitin suggest applying glue liberally to one surface only for face or edge glueing if the wood on both edges is no more than 2% different in moisture content.On mortise and tenon they suggest glue on both tenon and mortise because of the assembly time, the more glue there is the longer the open time.Often in the winter there is more joint failure because the heat in the shops is driing thesurface of the wood more, when it is too dry it wicks the moisture out of the glue too quickly and dries before assembly is complete.When glueing up for exterior I use titebond 3 and wet both side of any joints even the shoulders of the tenons, I fel it helps to seal the endgrain
