Your pretty much on with the smiths doin every thing nice and square , good job on threading , head space etc. any of the machine work , to assemble a rifle. Making sure the bore runs true when chamberings , crowning and all that fun stuff ... I can run a lathe, but doesn't mean that I think I'm a gun smith . I'd much rather pay some one to do it that has all the proper tooling, jigs and so on. Give myself all the parts to assemble a rifle and the exact same parts to a good smith , garuntee his will perform better in the end
