"Just". Yeah. We covered that bit in another thread recently.
So it goes like this:
Check headspace with gauges prior to disassembly.
Turn, taper-bore, and split aluminum rod to fit barrel contour @ chamber and Brownells bench-mounted barrel vise.
Turn plug gauge to fit new barrel's bore dimension.
Strip rifle to bare receiver/barrel.
Fabricobble receiver vise.
Crank the old barrel out of the action.
Check barrel threads, grind tool.
Check barrel contour and cut new barrel to length.
Set up barrel between chuck and tailstock center and profile barrel to match original. Can't do between centers due to lack of bed length.
Set up and indicate barrel through headstock to turn tenon, cut thread relief, and face shoulder and end of barrel to match original exactly.
Cut and skim threads until snug fit in receiver.
Ream chamber. Ream, install receiver, check headspace, remove receiver, rinse and repeat until correct headspace is achieved without removing barrel from lathe.
Mark and cut extractor and top bolt guide slots in barrel.
Turn threads and shoulder on muzzle, cut/lap crown (heheh!)
Polish and acid-color receiver, trigger, and lever. Polish bolt, maybe jewel it?
Cold-blue barrel (or Duracoat blue)?
Install barrel w/threadlocker, verifying indexing and torque. Check headspace (again).
Reassemble rifle minus forearm and sights.
Test fire and check brass dimensions.
Turn forearm mount stud, drill barrel, press and solder in place.
Cut dovetail for rear sight, D/T for front sight ramp.
Install sights.
Fit new stocks to rifle, fit buttplate and forearm escutcheon, and finish with hand-rubbed BLO.
Oil and put in safe with other four .30-30s
