Idid miss that comment. Lets just agree to disagree. Unless I know what the conditions are when you tested my thesis, I can't know if you were doing it the way I describe.
I can assure you that I Was as much a Skeptic about this difference as YOU ARE. It was my late friend who called me to his house, then took me into his workroom and turned off the lights, and MADE me stand there in the dark to wait for my eyes to adjust to the absence of light( not total, as there was a hairline crack under the door.) I felt as uncomfortable doing that as any of us would. But, I did it. I still did not expect to see what I saw. Then, being a skeptic, I figured it was just HIS LOCK that did this. So, I went home, took my flintlock from my gun, mounted it in the vise in my garage workshop, closed the doors, and turned out the lights. I had both a strip of leather, and a lead wrap that fit the new flint I employed. I was Convinced, from what I had not seen in daylight, That I was going to prove Don Wrong! AHA!!! Gotcha! :shocked2: :grin:
I failed.
So, please, keep an open mind on this issue. :hmm: :thumbsup:
There are other reasons to use a lead wrap around your flint besides hotter, and more sparks.
Lead is able to mold itself to the subtle, smooth curves in the surfaces of a knapped flint.
Lead does NOT GIVE when the flint strikes the frizzen. Leather does, and that rebounding puts chatter marks on the frizzen. Those chatter marks accumulate and ****** the scraping action of the flint down the face of the frizzen. In turn, that knocks off more of the edge of the flint, and reduces flint life. With a flint mounted so that the Angle of Impact of the edge to the face of the frizzen is 60 degrees, and striking the frizzen about 2/3s of the distance up from the heel, that flint will not bounce back when lead wraps are used.
The lead weight gives more mass to the end of the **** as it comes over the top of the arc, and gravity begins to assist the **** in falling down towards the face of the frizzen. That very small bit of increase in velocity makes for a better bite into the steel to scrape off sparks, using less mainspring tension. That saves mainsprings, and lessens the rattle and tickle of your sights while you wait for the ball to leave the muzzle.
I don't expect everyone to agree with me on these matters. Different lock designs created different possibilities and limit others. Some of the steels used in some of the locks still being made are less than optimum.
All this is possible in a well-tuned, and correctly designed flintlock. They actually did exist back in the 18th century. We now have some American-made locks that are of that high quality coming from the manufacturer.
