Warped drum shell

So i just noticed my bass drum shell is out of round by 2mm (0.0787401575 inches) I think its pressed down where the tom mount is, so in that way its a little warped. Im not sure if this is a mayor problem, i know it effects tuning and sound a bit and i dont know how it happened. Ive read on some forums that there are several reasons like: uneven tensioning of the lugs, extreme temperatures. Or my thought...that it got a little bent in the shipping. Will it get even more warped if i have the tom mount and toms on it?. I dont think the wood hoops are out of round just the shell. Is it worth replacing? chances are that the same thing will happen again in the shipping if i get another bass drum. I havent checked the floor tom yet but the 12" tom is 100% round. Maybe iam way too picky?.

OMG! My head is out of round! I measured it just today and found out that it is a few mm wider front to back than on the side to side. Yes, my head is out of round and it is less wide between the ears.

I think this was from the forceps at birth, but it could be from head bangin all day to loud rockin music! \m/ \m/

If you can tighten a head down on a drum it can still be played perfectly fine and sound fine. Put your head on straight and tighten 'er down, then wail away! :)

Actually, in drums, they are pretty often out-of-round. Any given shell can be out of round by as much as 1/8" (3mm) or more in some bigger drums. Mechanically, you just need it round enough to fit a head and have the lugs tune smoothly without binding. If the drum tunes fine, then there is nothing to worry about. When a head is tightened down on the shell it will help correct for it.

Are these the Yammies like your signature suggests?

2 millimeters! That's nothing to worry about.
As you stated, Thats just under .08 of an inch.
I thought that I was Anal Retentive.
I feel so normal now.

Wow, I didn't know it was that common. You're right, as long as the head seats well, that's all that matters. I would think it would be a much bigger problem if the shell twisted and messed up the plane of the bearing edge.

That is one reason why drum heads and drum hoops are slightly oversized.
The larger inside diameter of the hoop on the head compensates for slight imperfections in the drum.
As long as the head will fit over the drum without binding it is not a problem.

I have noticed that my vintage drums from the 60's and 70's are not nearly as round as my new drums from this decade.
I have also noticed that my vintage drums have more highs and lows in the round bearing edges than the sharp edged drums of present day.
