Thanks pal, you are one of the few who prob. knows how much time and revisions it took me to finally get something on paper that looked good
In manufacturing, the customer can send customer-supplied tooling to the vendor to reduce tooling and fixturing costs and send customer-supplied material so the vendor doesn't have to source a supplier.
However the vendor isn't going to let the customer send over a bunch of employees into the vendor's shop and just let the customer's employees start running the vendor's machinery and start jamming up the lunch room microwave. OSHA would have a field day with untrained non-employees running machinery and it would violate ISO QC processes, as well as cause all sorts of insurance and liability nightmares. That is a ridiculous statement. Maybe at a one-man operation but not any decent-sized company. They might send over people to review the process and inspect, but that is more along the lines of QC processes for aerospace.

i'm not in the machining industry, but it's done ALL THE TIME in other industries.
however- i was apparently wrong. PacNor's people produce noveske barrels- but on Noveske's dime.
Noveske: Our stainless barrels are made partially in ourshop and partially in Pac-Nor’s shop. And, the relationship that I have with Pac-Nor…I used to work there, and now what’s goin’ on is I buy steel, I take it to Pac-Nor, when the guys clock out of Pac-Nor, they clock into our barrel production. They machine my blanks with our tooling, which is all made to our design, including the drills, reamers, button, so forth, so on. They stress-relieve to our recipe, and then they give the barrels back to us, and then we finish them all in our shop.
The snippet you posted is fairly typical as the customer gets to have their stuff made the way they want and most do some processes in-house, and outsource other processes to vendors. Many send custom tooling and fixturing to vendors, otherwise vendors would have to make that tooling and fixturing, then charge the customer for it. When companies get tooling made, they have to chose from a variety of other companies so its possible Noveske weeded through a bunch of crappy suppliers before they found reliable companies to crank our their specific tooling. Some of our customers send over custom fixturing and tooling as well.
I've never heard of vendor employees clocking in and out for different customers. Keeping track of machining hours is typical for small prototype work where you charge by the hour, but production level stuff has a machine shop running X quantity of parts for a price quote. A machine shop will be running dozens of parts for dozens of models for dozens of customers at any given point so production is staggered in various stages of completion. It's not like all machines start and end the same job at the same time. Maybe it was stated that way to simplify the process for laymen interested in an inside peek.
Either way, those barrels are in the hands of top notch companies. I have one of Noveske's 18" Mk12 3-groove match barrels (not their polygonal rifled SPR barrel)for my SPR. Good stuff, I'd like to drive south and take a tour of the Noveske facilities some time.

As a High Power shooter, I would be curious to hear your barrel life results with actual barrels, in the calibres you have shot.
And the reason I ask is that as you have stated, there is a big difference in how long a barrel shoots good to a 100 or 200 yards, vs 600 and 1000.
