thanks again all.
update - took the heads off the floor tom.
1. the edges aren't flat (true)
2. the hoops aren't flat, and are also out of round, one of them so badly that a new head won't go in without squeezing.
3. the shell is possibly out of round. gonna have this dbl checked by the best drum repairman I know.
4. the smell of spraypaint almost knocked me out when I took the first head off.
5. the drum will not tune - the badly bent hoop being the main culprit.
6. both the 14 and 12 are possibly recovered.
too bad because the 20+12 sound thunderous....
did I mention I NEED A REASONABLY PRICED POWERTONE.
