Tower Pistol - the Saga Continues

[webfoot10]

Heat the frizzen to a bright yellow as redhot is not hot enought.
Then take the hot frizzen and drop into a can of powdered bone
meal, be sure to completely cover the frizzen. The hot frizzen
will absorb the carbon in the bone meal, then reheat and quench
in ATF or cooking oil. Then clean and try the file trick. If not hard
enough, repeat untill its hard enough to spark. A trick from one of
my blacksmithing books.

Here’s a happy update.
I was hesitant to try the suggested surface hardening procedures for fear of damaging the frizzen. While discussing this with a local gunsmith, (who has always been more than helpful) he checked the hardness of my frizzen with a carbide tool and believed it was fine as is. He did note the frizzen spring was really strong and kept the flash pan from getting a strong spark. The flint striking the frizzen didn’t slide down the frizzen face, more like it hit and stopped in the same spot. The flint impact raised the pan cover about 3/8”. I mentioned that it seemed the hammer didn’t travel very far upon pulling the trigger. There wasn’t much of a hammer swing. He said increasing the hammer throw would require adding metal to the sear-like rotating catch, while the frizzen’s cam surface, where the frizzen spring holds the frizzen closed could be dressed to reduce the force needed to uncover the flash pan.
I asked him to take care of the hammer throw and frizzen tension. The results are more than I hoped for.
I also replaced my missing ramrod with a brass lavatory sink drain pull-up handle I found in a mom & pop plumbing supply. And I discovered a jar of bone meal in the back of our pantry, in case I need to face harden anything in the future. Thanks again for all the helpful suggestions.
