I am a beginner and just wanting to know how to mill a 7 degree angle using a vertical mill. I can get a 7 degree end mill cutter but I want to mill the male part of a dovetail. The only angle cutter I see you can get is smaller on the end so the angle this would cut with the vertical mill would be narrower at the top and wider at the bottom. I need the cut to make a dovetail that is wider at the top and narrower at the bottom. If this makes any sense could someone tell me what I need to make this cut???
