* OK, I can do the math, but I don't know what assumptions to make.
F'rinstance: A piece of lumber 12"x12"x3/4" is a 1x12x12", but is it
calculated at 1bf or 0.75 bf ?


Jim,


The place where I buy would charge me for 1bf, for the piece you decribed.
They would plane a 4/4 board down to 3/4, and therefore need to charge for the
entire thickness. As for the calculation for your cut list, you're askin the
wrong guy. I just let the man use the calculator, then I pay. Have fun.
