help - 70-200mm tripod ring

[crockny]

I tried to take off the tripod ring and managed to unscrew it - but now I want it back on and it won't screw in!  I'm in a big hurry too for a photo shoot ...

There's a bit of felt-like materials.  Try to squeeze the two-halves together before screwing it back in. It helps to have another person helping you.

Well I called Canon support because I had a shoot - they said it doesn't actually screw in and out - that there is a flange that's supposed to catch - anyway - they couldn't help me except for the info - after I hung up I noticed there was a noise like something was loose so I shook it down and low and behold it seemed to catch - the gap is not totally closed but it seems solid and is not moving - go figure ...
