Pryor Mountain Bill had a booklet on forging gun locks Of course you'd need to be a journeyman level blacksmith to consider it.
Not so. One only needs allot of material, often lots and lots of material, allot of coal, often lots and lots of coal, and allot of time to spend learning the skills and hammer control required to forge gunparts...and lots and lots...and lots of patience.
Oh, and it is MUCH easier, MUCH less time consuming, MUCH less expensive, and MUCH easier on the psyche and the psyche of the wife and kids, to learn the requisite techniques by "forging" modeling clay lock parts to a predetermined pattern, using miniature hammers and anvils bought at yard sales and flea markets, prior to firing up the forge.
However, a journeyman class smith can do it in less time with fewer meltdowns.
Just kinda thinkin'...typing out loud, so to speak.
