I really feel stupid sometimes. The other day I was making a bird house in the garage. The roof has 3 sections - left side, right side, and center. The center piece is beveled on both sides, while the side pieces need to have matching bevels to fit again the center. The left and right sides slope downward and an angle (miter cuts in the front and back).
Suffice to say I made a few cutting errors and now need to get something together with these 3 pieces. The problem is that the left and right roof sides, I believe, need something like a 50 degree rip cut. What I mean is, if you look at the left side from the front, top facing up, you would have to bevel the blade on the BT3100 further to the right than it lets you go (by, say, 5 degrees).
So how do I get this cut right since I can only bevel from 0 to 45 degrees? I am thinking that I need to set the bevel to 40 degree (40 + 50 = 90 degrees, right), and then run the piece with the waste on the left side (fence side) of the blade, and the piece turned upside down (at least for the left side). I am on the right track? I feel like I have a mental block about this. And, believe me, I'm not that bad at math and geometry and such... just can't figure out this angle.
