Hi to all! Ed is going to post some pictures of the receiver repair set up and a small description is as follows....
First picture shows all the parts and pieces.
Second shows a mock up on a 1920 receiver.
Third shows the spring steel shims & expander block function to spread forks all the way to the chamber. (.475" block + 2 X .020" shims = .515" target width dimension)
Fourth shows muzzle securement
Fifth & Sixth, receiver forks secured for straightening....
Also note that the aluminum bars can be moved out parallel with the fixture, or the receiver and block can be moved in to clamp halfway back or more.....
I just clamp two bars, alum on the outside, and steel on the inside.... to torque & twist on the forks with....
Anyway, that's how we roll on the GT Specialties work table of "crying and sobbing uncontrollably"......

......Best to all, til...lat'r....GT....
