I just had my 10 gauge hammer Elsie apart. I drilled a hole in the side of the wrist (under the plates) and made a little tool. I took a flat U style clamp I had laying around. I drilled a hole through one side through which I inserted a small bolt. A nut on each side of the clamp and the bolt is tight with no movement. I then put the one side of the clamp on the far side of the wrist, inserted the bolt through the drilled hole in the wrist and let it push against the top lever shaft. I then just kept tightening clamp and doing so caused the bolt to push against the lever shaft pushing the spring over so the trigger plate could be aligned. It was simple after I made the tool. Without it it was a bugger trying to get it to move.
