Re: Stuck trying to take gimbal ring out
this is only a suggestion but can a friend with a stick welder weld a threaded bar around the hole (which is stripped) leaving enough showing so you could put a socket which is larger than the outer diameter of the stuck stud,and thread prutruding through the 1/2" drive socket, a couple of solid washers and a nut and draw it out by rotating the nut.
hope all that was understandable.
