Read your calculator's instructions to figure out how to get this calculation. M = Miter angle of saw B = Bevel angle of saw T-1 = Inverse tangent. This is the. I am trying to build a bird house with a Japanese lantern design, consisting of curves and tapered angles. Saws start to differ when you look at their blade diameter—commonly 10 inches or 12 inches. A miter saw’s main function is to make a long board into shorter pieces, while a table saw is best for cutting down the length of a board to make it narrower. The most common angle between walls is 90. So, since we needed to be 20º from the fence before, we will subtract that amount from our current jig angle.
