Weekend project,going to start a new tri-lam with a raw boo belly. Want it to be between 45 and 50lbs 64" long. On a normal tri-lam I would make my core 1/4" tapered to about an 1/8 and add a belly lam about an 1/8". Question will the raw boo about an 1/8" add more or less weight than say an Osage lam. What I'm going to do is glue up the core wood and boo back, tiller it to about 30# at 28" and then glue the raw boo on the belly. Then I should be be close with the tiller and just have to take a bit off to get it were I want it. I heard that you should temper the raw boo belly, is that necessary, can you do it with a heat gun? Any advise would be helpful thanks
