if you want to change it, you grind the weld off, and then knock off !

Just a word about following Jonno's advice. We did just that at barnsley and the weld actually snapped on the gear.

It works but we stuck in a 5mm bit of silver steel held in with some araldite too just for a bit more security and you can still take it off.
