Sorry everyone for not returning to the thread sooner, pretty bad form on my part!

The 488 can be dismantled, so all is not lost. I'm sure I've got details somewhere if you want them.
Have you still got those? I think that might be my only option.
I did try the suggestions on this thread (oil, tapping, even remembered I have a powered screwdriver) but the tightening screw will still not turn. Although it would not surprise me if the instructions say to remove that screw first!

Gee, I just got mine last week and it didn't seem bad. What legs you have with it? I have the 3021 and the 190XB.
My tripod is just a cheap one I bought on eBay as part of some liquidation sale, a Qentis. Never heard of them but at the time it was being heavily recommended on some British forum for being sturdy but incredibly cheap, only £35 ($70) for a carbon fibre! I think it is made by one of the Chinese clone manufacturers.
I have had the Manfroto head for a couple of years and never had any problems with it. My heavies lens is only a 70-200/2.8 but it has never slipped. Even now the ball still works, it is just the panning feature that is stuck, so it has become a bulky 486 in effect. Despite my problems I would still recommend it. Just a bit strange that it has become stuck when it was fine the last time I used it, which was about a month before I discovered the problem.
