From what I have seen, most modern drums use some form of relatively sharp 45 degree our double 45 degree cut, with a few using 30 degree or 60 degree cuts. But for a vintage sound usually a round over is preferred.
To cut the famous double 45 I know you have to router both the inside wall and the outside wall. But what about round overs? Should I do just the outside, just the inside, or both somehow? And what would determine the bit size I use, shell thickness? If I have a 3/8ths thick shell should I select a 3/8ths router bit?
