PJs, I stumbled upon that finish by accident. I was wanting to brass plate the side frames using brazing rod and torch and then mill them down to a smooth mirror finish, but as I do so often I design as I build. I spattered a layer of brazing rod on to the side plates and buffed with a bench grinder. I looked and looked at that and decided to go with that appearance. The side frames are .20 hot rolled plate, nothing fancy.

Sorry for the delay Sean. Congrats on your build. I will very soon be turning 81 yrs young. I have loved metalworking most of my life, although not being directly employed in the field. I have spent the last 50 yrs or so in the electronics industry both private and govt.
I began gunsmithing in the mid 1960s as a hobby, I also have a love for horology as I served a six year apprenticeship in watch and clock repair beginning at age 13.
That's enough of that, Your best bet for building a rifler is to locate a cheap small lathe and modify it for the twist ratio that you need for proper bullet spin. This can be done by mechanical or electronic servo control for draw and twist of the rifler tool. I have viewed several similar projects on you-tube so that may be a good starting point for your project.
Good luck, Be safe.
