Now that I pretty much decided on the Siler lock (with the help of all you guys) how tuff is it to assemble the kit form of the Siler Large Flint Lock? I know the parts have to be hardened, I have oxy/acet capabilities here, but have never done this sort of thing before. I think the diference is about $45 between the kit or the finished lock. I'm always up for a challenge but am I looking at the wrong challenge this time. What are your thoughts. Uncrichie...
