No other option but to knock it home, after a few thumps I noticed the whole of the frame assembly had bent at the bottom, I still had about half an inch of tube showing so rather than cause more damage I cut it off with a grinder.
Im really annoyed I did this but on reflection I'm just as annoyed by the poor design of the stand pivot, how much simpler would this have been with just two collars at each side of the frame.
The stand is now attached and I'm hoping it wont intefere with the wheel when it refitted or it will have to come off.
