Mr. Marrakai,
I do intend to build them from scratch, with the proviso that I'll subcontract such tasks to others as they can be done better or more efficiently.
However, as a starting point from which to gain some experience, I'll probably end up converting a shotgun as well. (My wife could make good use of a nice, light 30/40 Krag for boar anyway.)
I figure the place to start is...not to, until I've learned everything I can about these fascinating rifles. To me, that will mean gaining a prety strong understanding of bolting systems, pros and cons of the various action styles, metallurgy and manufacturing methods. Pretty much, this work will become something our shop will develop a skill for, if we're successful.
Thank you for your generous reply and encouragement!
