Before I go too far in disassembling, I was hoping for some expertise on this... I've got an old 3047 head on a 3040 leg set. The left/right tilt axis isn't cinching up solidly any more, even with the handle turned very tightly. Looking at it and looking on-line doesn't show any reason for this to be slipping. It appears to be a tapered shaft mount that to get to, would require a very complete disassembly. At that point, I'm not sure what that would do to allow some repair, anyway.
Any ideas on how to firm this connection up? I've got another, working 3047 (newer model) in the drawer to replace it but I'd like to get it working again for some head shuffling I'm embarking upon with other leg sets.
