My rehab of a 12 X 15 WFL floor tom has stalled out. I've discovered that the shell is slightly out of round on the reso side only. I suspect this is probably because it was left without a bottom head and hoop on it for a long time. The shell is stripped down to bare wood, and when I tried to fit a head on just to check it out, I could just barely force it on, and it's stretched kind of oval with waves in the head developing at the 'points' of the oval. There's absolutely no way I'd be able to get a head on it once I re-wrap the shell. The batter side is still fine.
Has anyone here dealt with this type of problem before, and if so, what did you do? Is there anything that can be done to get the reso side of the shell back into round, or close to it?
Thanks.
Scott
