From the picture in post #20 it does rather look as though someone in the past has replaced the hex headed bolt with one that had a larger head that has been turned down to fit the slot, but doesn't grip - unless as I said in an earlier reply the circular head is actually eccentric and locks against the shoe. :scratch:
philf:
Has the previous owner turned the hex (or square) head off the bolt?
awemawson:
Could easily be cured by drilling the bolt head radially and pressing a roll pin in
mattinker:
I just went back to the original pick, I had missed that it had been turned round. Andrew's solution is probably the easiest if you haven't got a welder to put a ridge on the head of the bolt. Normally the hex head is held in place in the groove.
Although Andrew's solution is viable, it will leave slack in the movement. Four welds to transform the head into a squar would eliminat play!
Regards, Matthew
philf:
How about making a simple clamp to stop the head turning:
A grub screw (or 2) from the side could lock the round head. The width of the block could be a snug fit in the slot in the shoe.
