I have a Benbo tripod with a squeaky and sometimes hard to tighten/loosen bolt I've been trying to figure out how to disassemble. There doesn't appear to be any screws of any sort around the joint, and I'm not sure how to get it apart besides fully unscrewing the bent bolt. Is this safe to do? Will I be able to get the tripod back together afterward? I've tried doing this but beyond a certain point it gets much harder to turn and I've been unwilling to go any further out of fear of damaging something.
