Thanks Roy, I do hunt with my Leman, leaving the hammer down on the cap. I have also struck the hammer, as such, with a rubber mallet a pretty heavy blow and have not made the cap discharge. I'll probably make the fly anyway unless someone can tell me that the Vincents don't have one.
And thank you Mike for your support.
I think this will probably be the last installment of lock building, as the work is basically done, unless someone wants to see it after it's shined up.
This morning I got up early and fired up the forge. I hardened the mainspring in a water quench. I would normally also do the tumbler and the sear but I've not yet decided whether or not to make a fly.
Next comes the, somewhat, contraversial part. I bury the hardened parts in a crucible full of sand and put it on the forge to "cook". It will stay there until the coals burn out. or about an hour. Then I let it sit until cool
When cool, I clean up the parts and assemble to give it a trial run. here is the new lock at full cock. I filed, only the full cock notch for the time being. The notch was filed where the tip of the sear lies on the tumbler when the hammer with the new mainspring is pulled back to it's reasonable limit.
Everything works like a charm. nice and crisp. I worked the action about 20 or 30 times. If the mainspring has not broken by now, it probably won't.
That's about all it takes to "roll your own". I'm going to put it on a rifle now. If anyone has any questions, I'd be glad to answer them. Thanks for looking.
