Thanks jonnistix, you make some good points. I will check the bottom hoop but not sure why you think something is amiss. I don't see it but I am a beginner in the drum world.
If you look at the top picture, showing the snare side of the drum, you will see the uneveness of the hoop in relation to the head. The gaps around the edges are visually uneven. It is very pronounced. That is what I see. It could be uneven tention, which again ids not really good for a drum, especially if it has been stored that way over a long period of time. The parts of the shell and hoop have what is described as "memory", just like we do. Our muscles are trained over time to reproduce certain movements without avtive thought, like when playng, a flam is automatic, after you train the muscles to repond to that command.
So too the parts will "train" themselves over time, and it could cause the shell and hoop to warp. Not saying it has, only that there is a possibilty. Then again, it could be distortion of the picture, as it seems to have a "fisheye" effect goiong on. I always look for this sort of thing, it keeps my brain active. Having been a saleman and restoration geek for years, I look for detials, and miss many more, as some of the other members point out regularly, but it is all about learning what we are doing.
I hope this turns out good for you!
