Here is the start of 2 snare drums my drummer friend and I are doing. They are both made of cherry. Both drums are stave style. One is going to be a 10" x 6" deep "popcorn" snare, the other is going to be a 13"x3" piccolo snare. So far I only have the staves glued up. The previous drums I built I rounded the outside on the lathe and used a roller jig with the router to round the inside. These drums are too small to get the the router inside to do that. I am unfamiliar with "hollow form" turning, I'm not sure if this would fall into that category or not. Whats the best way to go about rounding the inside while keeping the wall thickness consistent?
