So when you found it was going to be 25°. When you go to cut the piece how do you know how much to go? I usually just kept things at a 45° or if I'm using a 4" DS I'll go 2" up and down from center line. I guess my question is instead of measuring in length I'm trying to do more angles in degrees and wondering if I know my angle is 29 I want do I cute my "pie" at 29° from center line because right now I try to focus on whether my measurements are coming from top center or bottom line. Hope that makes some sense and you can help a brother out
