FYI The Standard Steel Company in Lewistown Pa. made barrels back in the day. They turned them with lathes that could be seen rusting up in the yard today.
that would have been interestingIt's not my picture. It's been around for a while.
I did work in defense contracting on some pretty cool stuff, but I am civilian. The Hydra 70 rockets were a fun project for me.
Rusting lathes are more heart breaking than a trip to the pound!FYI The Standard Steel Company in Lewistown Pa. made barrels back in the day. They turned them with lathes that could be seen rusting up in the yard today.
That's a tough comparison but I feel your pain.Rusting lathes are more heart breaking than a trip to the pound!
That is actually a broach. Broach rifling is a form of cut rifling, but cuts all grooves simultaneously. Ernie Stallman at Badger Barrels perfected this process for precision small arms barrels.This is the cut rifling head for the 16" guns on battle ships.

Imagine changing the chuck on that one......Watervliet is who makes the barrels

How much JB does it take to clean one of them big ones?
Probably didn't care, either.I was an M1A1 tanker and never knew about how the barrels were made.
Cheaper by the 1000-ct on sale at Graf and Sons.The hundred count boxes of these are heavy.
Now that's a powder monkey.View attachment 1182643 800mm Gustav
Wasn't the need to reduce weight on the M1A barrel where CF barrels really caught on ? Typically unlimited budget to explore....View attachment 1182649

Not quite the precision required, perhaps, but consider the fixtures required to bore out the forged 50-ft propulsion shaft sections in a modern aircraft carrier:I work less than a mile from the Watervliet arsenal. Future son-in law works there.
I have worked on site there many times (outside service) but never worked in the forge area.
They have some monster lathes in there!
