Eric Johnson demonstrates percussion distributing explosion to the interior of the weapon - Jim Surkamp

 

Eric Johnson (from the video):

 

en.wikipedia.org/wiki/Flintlock

"You see, as nice as that flintlock is, it doesn't work in the rain, as we said, it doesn't work too well in the snow, it doesn't work in the wind or storm.

 

en.wikipedia.org/wiki/Alexander_John_Forsyth

A man named Alexander Forsythe, a reverend in Scotland, came up with an idea of a fulminate. A fulminate is something you can pound. en.wikipedia.org/wiki/Fulminate_of_mercury He specifically thought about mercury. And he started to experiment with that. The Tower of London thought that was a screwy idea, then thought: "Well, maybe that will work, if it is an explosion." So what was going to happen was - you see there's a small appendage on this called a

"cone" or "percussion cone" or "nipple." There's going to be a cap. There's going to be a cap, a brass or copper cap, filled with a substance called fulminate of mercury, that's gonna stick on top of this nipple. So, that when you pull the trigger, the hammer hits it, and if any of you are drummers, you know what percussion is: "to strike and to hit" -

that distributes an explosion into the interior of the barrel. And the nice thing about the percussion system - for the most part - is it's water-proof. Ah . . . now you can fight a battle in the snow, the rain, the ice, and the cold. You don't have to have the most beautiful day of the year to fight the battle.

 

Well, technology is progressing at Harper's Ferry Armory in Jefferson County and other armories. Part of the function of Harper's Ferry was to make pieces called pattern pieces. And they were specifically making things to go into the national arsenal for the regular standing army. But they also made pieces that could be sent out to contractors like Robbins and Lawrence,

Whitney as we mentioned, and some other people. And those folks would create from those template pieces other model pieces and they would stock state arsenals with them. Well, the problem with that system was sometimes a contractor gets in a hurry, and sometimes to make quota, to get in on budget, you might cut a few corners. I'm not saying they all did that, but I am saying it certainly did happen in this period. Some people did that. So what you find in a lot of existing state arsenals in places that have collections of weapons of that period - the antebellum period right before the Civil War - are pieces that need some attention and care and they are pieces that need to be maintained, and needed to be re-inspected."
