So I have a 1967 Ludwig Silver Sparkle 13" tom with the original mount on it. I recently took the drum apart to clean it and now, once reassembled, the mount keeps loosening from the shell over the course of a few hours playing. I keep having to take the top head off the drum to tighten the mount's screws. I get it nice and snug, not overly tight, but then after playing for a few hours I notice the mount starting to get loose again. I know I reassembled it correctly, so that's not the issue. I've never had this problem before.

I do have one suspicion: My rehearsal space has been getting colder lately. Here in Georgia, the temps are around mid 30s - 40 in the morning and then it heats up to the mid to high 60s. I wonder if this flux in temp is causing the wood in the drum shell to expand when it's warmer, then contract when it's cold, causing the mount to slowly work loose. Also, when I arrive at the space to practice, it's pretty chilly, but after a few hours with a few warm bodies in the place, it heats up quite a bit. It's strange, the mounts on the floor tom are snug as a bug in a rug. I know the mount on the 13 takes a little more pressure though. Also, I break down my kit after each rehearsal, so maybe taking that weight off the mount on a regular basis is contributing too.

Guys... anyone experience this same problem? Remedies? Thanks in advance.
