Re: Blueprinting a Model 70
I hate questions like this because I always get self conscious about sounding like an arrogant person.
How I do stuff is largely different than what the masses are doing. (don't start stoning me now as I'm not claiming better or that what someone else does is "less" then what I do) I say this because I don't profess to know or be skilled in the ways that most gunsmiths true an action or fit a barrel. I've gone in such a completely different direction with my stuff that I'm a poor choice for an opinion.
I don't have a crystal ball into other shops to see what they are up to. I would imagine that it starts with you doing your homework as a consumer. You research a potential smith and see what his feedback/reputation is. You then ask if he can do the work your after. Most of the guys at the higher level are pretty straight up so if they say sure, then I would have to assume you'll be treated right.
What were talking about is not rocket science. This isn't mold or die work where you have to accommodate for material shrinkage, elongation, distortion after heat treat, work hardening, etc.
It's rather simple fundamental machine work just ensure stuff is running on the same center, is round, and at right angles/parallel to one another.
