I have been messing with a L&R replacement lock in my Dixie squirrel rifle for a number of years without any real joy. I've polished up everything inside, played with several frizzens and various hardening techniques, and nothing I had done made it any better than maybe 50% successful. The problem as I saw it was when the hammer was at rest, the flint was pointing at the frizzen pivot and not the pan. So along comes the April 2022 issue of Muzzle Blasts and the article about bending the hammer to get better geometry. Ah Ha! Except I have a double throated hammer that can't be bent. So I called L&R, and they do have a hammer that will work in this lock. I ordered one and it came in quickly. It had the same deal going on, but I was able to get it hot enough with a Mapp gas torch to bend it, and I closed it up about .100" so it just clears the fence. I did have to file the bridle slightly so the tumbler wouldn't hit it since the hole was not in quite the same orientation but otherwise it fit. Put it back together and now the flint hits about half way down on the frizzen and throws a huge shower of sparks right into the pan. It should also be easier on flints since now it's a big scrape instead of crashing into the frizzen. I tried it with priming powder and it was 100% for 10 shots. I think I am going to be able to finally enjoy this rifle and super happy it's working now. Something to pay attention to if you have a unreliable flintlock.
