Starting my winter pistol build early

[ChuckJonesWagon]

So, I'm using the broken cast piece to form "dies" out of maple scraps. I've cut the brass sheet (.80) and began to peen it. I will say, this is the first buttcap I've ever done. And I want it a bit deeper or "cup like" so that takes more pounding.

I have discovered that it's not a "fold up the metal" process.....but more of a "push out the shape" process. I'm using a thick brass punch as well as a ball peen hammer and that broken cast piece.

The most use is coming from the brass punch. It seems to push the metal where I'm asking it to go vs a ball peen hammer.

When I laid out the brass sheet for cutting I took the broken piece and "rolled it" from left to right, and front to back to obtain (what I thought) would be the right amount of sheet brass. Well, as the process goes on Im finding out that I'm pushing the brass to form the piece. As such, I'm cutting off more of the metal at the top. In other words, I started out with to much or to big of a brass piece. Right now I've cut off a good 1/4" from each side....yes....a bit more than a half-inch. But....better to have more and not need it, than not enough to finish it.

I'm not done....but closer than when I began this piece.

Moving forward. Not done but getting closer!!

Well, sometimes things just don't go the way you think. Now, this was the first time I've ever peened a buttcap from sheet brass. So, there was a learning curve.

What I learned was I kept peening the bottom of the cup thinking I would draw in the circumference, or outer lip of the cup. That does some....but not as much as I needed. After far too many whacks I stopped to discover I had too much material to get the outside lip "smaller". So, I cut of the excess. (And my "rough" finish was as you see above.

So, once I had it as above I began to cut the butt to inlet the buttcap. After some time I gave a heavy push on the buttcap and CRUNCH.....the cap buckled. The base was just too thin from over peening.

Now, before I even began the inlet I saw the bottom was thin, so I soldered a reinforcement piece inside. But after the CRUNCH I tried to solder another piece and I had to use a brass color silver solder. Well, the heat was just too much and I began compounding the problem as the pic below shows.

So....after too many hours spent trying to fix what is unfixable, I scrapped this one and cut a piece of sheet brass for a new one. Lesson learned from screwup #1 so this second one should go much smoother!!

Since it's hunting season I'm spending little time on this pistol build....but that will change after November.....until flintlock season is over in January.

Buttcap #2----the sequel.
