If you use a sledge hammer and a proper chisel, the job should take no more than 15 minutes even for your first try. I let my mom give it a try b/c she wanted to. Altho she was much slower due to sheer power output, she probably did 25% to my 75% of the cutting. Not bad for an old lady. Anyway, the point of the anecdote is to emphasize how easy it is to cut the inside out with a chisel.
Ok I'll have to look at the top of my drums again but it actually cuts through the metal correct? I'll have to go try and find a good chisel to get and you used a sledge?
