heh, buddy . . . don't denigrate us manufacturing guys! I believe gfugal's points (1) and (2) and Chris' post are correct.
so if optimal grain orientation is what makes laminate layups better, how should DC cut the lams for his recurve?VG on the back and belly, with a flat grain core?
QuoteAnswer his question if the rest of us are wrong. Ok, PD I will try to clarify, even if you are talking about something different than the OP.If "his question" was....QuoteSo are three stronger than two?Then yes, as there are benefits to minimizing defects in the materiel, which is what we do when we swap ends, make multiple lams or build glulams and I-joists. Making a limb with minimized defects bend further than a comparable limb with the original sized defects, might be called stronger in a sense. More bend stores more energy.if "his question" was..... QuoteIs a laminated piece of wood stiffer than a solid piece of the same dimensions?then, No. The stiffness would not change unless the glue itself had some extremely superior properties. There are of course, those claims made for Perry Reflex, but I do not think the OP was asking about prestressing the pieces before glue-up.
