New hammer and bolt arrived. The hammer needed deburring around the base of the hammer cam. It looked like they had drilled the hole and shoved the cam in without deburring the hole. That cleaned up easily. Also, this cam isn't goobered up the way the other one was.
The legs on the new bolt were quite a bit longer than on the original preventing the hammer from rotating back. I ground off about half the extra length and the hammer cycled fine. In the photo they aren't lined up right so just compare the tips beyond the concaved part that rides on the cam.
Here's the bolt/trigger spring with both sides lightened.
Fitting the bolt took a bunch of times in and out to get it right. A little at a time did it.
With the old hammer and cam, this is where the bolt came up. Way too soon, even for a 5-shot cylinder in a 6-shot gun.
Here is where it comes up, now. Much better and the percussion cylinder still works right.
Best of all, the action is
smoooth. I'm pleased. Now that the thing works fine, I can cut the loading channel get on to turning this into Dance Wannabe #2.
