First thing I do is use a center tool on the LE then cut my slots or holes for the hinges, then I mark the top and bottom with a line where I want the angle and use an electric palm sander to get my bevel. I have done a lot of them so the sander is just how I do them, I also use a palm plane once in a while then sand. I have used angle stock on more then one build too. How ever you want to do them is the correct way.
