So some time ago I had picked up a.45 percussion rifle that need a new sear.
It's a Russ hamm lock that has what appears to be a cast brass or bronze sear . Non magnetic for sure.
Couldn't find an after market one so had to modify this one.

With some help from a fellow muzzleloader, Benny.
How'd it go you ask
I just ordered a replacement lock from log cabin shop.
It'll be here next week . :luff:
The modified sear works ok but it dimensions just arent right. Very touchy, and the tails a little long.
Good thing is now I have plenty of spare lock parts.
Learning experience.

Good idea on the replacement.
That Benny guy knows stuff, great resource.
That kind of reminds me of my experience at the CdA rendezvous.
The rifle kept jamming after two or three shots. I had been in contact with L & R about the problem, but they had no idea what was wrong. I finally figured out that the sear arm needed to be bent. I figured if I broke it, no big deal because it didn't work anyway. So, I cold bent it just a tad and it worked great. I shot the trail walk at the Moscow RDV with no problems (except my own poor shooting).
L & R said it needed to be heated first. Oh well.

Hamm's locks were never really highly thought of, about the equivalent of many of the "hardware store locks" from the latter-half of the 1800s. Usable, but sometimes a headache. Back in high school (early '80s) I gave up on fixing them and just went to making new parts. A sear isn't too hard to do if you can source some angle iron the right thickness.
Once you get the RPL lock in place, you could repair the Hamm lock and use it on a pistol. . . .
