The Avro York used quite a few Lancaster bits. It was used in small numbers during WW2, and for some years after.

Thy type saw quite a lot of postwar use in Canada:

And just because I stumbled on it, here's the Handley-Page Halton, the civilian passenger conversion of the Halifax:

"RSM said 'guard the plane', but he didn't say where I had to stand to do it..."

Bit pregnant-looking, but not a bad looking bird to my eye.

5700 fps with a 16 incher...that'll leave a mark.

Multi Purpose. Can measure the speed of pee at the urinal( ) when set at 150fps expected speed, to perhaps rail guns when set to 5760fps.
All joking aside, of course you also have to set caliber.

Nice video, I knew most of the volunteers that did the restoration of that Halifax in Trenton. Lloyd Wright flew the Halifax During the war and he was a fixture for the whole restoration along with many others. Another WWII veteran volunteer was Bev Renshaw who was on Corvettes during the war. After working on the Halifax for years he said “if I’d known airplanes were this interesting, I would have joined the Airforce instead of the Navy during the war”

These guys put in thousands of hours of dedicated work to see this project to completion. It was a privilege for myself and 2 other guys to redo the fabric covering on the ailerons for this Halifax. It was a pretty small effort on our part compared to the dedicated crew of volunteers but it makes one feel good to help out in a small way.

One guy who was an iceboater from Hamilton visiting Trenton was shown the Halifax during the rebuilding project and wanted to help so was given the tour and shown some of the challenges. The H frames for the landing gear were severely corroded and needed to be completely rebuilt so he quickly said he could do that. A few months later he returned with the parts fabricated. The many volunteers who worked on this project did an outstanding job.

16-inch naval gun rifling cutting bit tool.

16" Rifling Head. The individual broaches were adjusted simultaneously. Each pass took .002" - .005" greater depth of cut than the previous. The head started at the muzzle & came out the breech. After it came out, the broaches were retracted & the head was pulled back. They were adjusted out another .002" - .005" for the next pass. Due to the amount of pressure, every other broach seat was left open. This meant that after the entire length of the liner was rifled to the specified depth, the head was indexed so the the remainder of the honed bore was rifled.
Per Bob Rawls, who works at Watervliet Arsenal - "the rifling head was at the Watervliet Arsenal museum. There were always questions on the 16" gun so I took the head off the tool rack and loaded it on the yellow cart. There is another 16" rifling head but not as complete, at the museum." comment from 18 Feb 2020 3:10PM
I've seen it stated that it would take about 60 hours to make one pass. I'm not 100% sure about that assertion, since there's no official citation with that, but here are some figures for the ballistics of the gun, and how many passes it would take, by their figures, to cut the grooves to depth. This is based on the 16"/50 Mk 7 gun.
Length of the gun, inches - 816.00
Length of rifling, inches - 682.46
Depth of grooves, inches - 0.15
Number of grooves - 96
Twist is uniform, right hand, one turn in 25 calibers (400.00 inches)
So, if they are accurate in their statement that they take off between .002 and .005 per pass...
at .002 it would take 75 passes to cut 0.15 depth
at .003 it would take 50 passes to cut 0.15 depth
at .004 it would take 37.5 passes to cut 0.15 depth
at .005 it would take 30 passes to cut 0.15
Based on the text, you would then have to index the bit, and cut again for the rest of the grooves. So that would seem to indicate you're cutting 48 grooves per index. So X 2 for the number of passes to cut all 96 grooves.

U.S. Navy Damage control teams work on saving the USS Pennsylvania BB-38 after being torpedoed in 1945
Note hoses coming out of the three 14" barrels in turret #4.
On August 12, 1945 while anchored in Buckner Bay Okinawa, a Japanese torpedo bomber slipped through the defenses and torpedoed the USS Pennsylvania.
The torpedo blew a 30 foot hole in the stern, 20 sailors were killed and 10 injured. The flooding was stabilized over the course of 6 days and the Pennsylvania was towed to Guam where a large patch was welded over the torpedo hole in dry dock.
After these repairs, the Pennsylvania sailed to the mainland USA using two of her four propellers. During the trip, one of the working propellers along with its shaft dropped out of the ship and had to be cut loose, leaving her to continue the trip on one propeller.
Not deemed worthy of permanent repairs after the war, the USS Pennsylvania survived the nuclear tests at Bikini atoll and was sunk off of Kwajalein Atoll on February 10, 1948.

Working on the ship was a naval officer, Lt. John (Johnny) Carson. Wonder what ever happened to him?? LOL!!

Added bonus. Same ship in 1938, Auxiliary steering room. "We don't need any stinking coat racks!"

My girlfriend and wife to be stopped in Trenton for the first time and saw the back/side door open to the restoration shop and where standing there taking in the view of the Halifax being worked on. A fellow noticed us and invited us inside and gave us the informal guided tour and and walk around. As it was lunch break the old boys wrenching on the project where seated down and doing lunch and our guide turned to us and claimed there is probably over one thousand years of experience seated at the table and as most of the guys looked in their 70s or 80s I believed him. Lots of before and after pics, engine that in the before pic was a ball of mud and scale and returned to something that turned over (not started just turned over) and looking factory new. New stuff to see ever couple years when I stop in and walk through.

Reminds me of the mascot K9 that lived with the Dam Busters.
I think his name was similar.

Similar but much more politically incorrect these days, as a francophone professor in Ottawa found out recently.

When I was a kid lots of black dogs were named "niiiiir". It seemed to work out OK for the dogs and their owners.

That's an amazing job of damage control. Thanks for calm seas, helping hands and air superiority to pull it off.

3 years ago I lost an old friend who did 33 missions over Europe as a tail gunner in a Halifax. He was wounded by a flak fragment and lost many friends. He said he watched a lot of young men grow old sweating out the risks and hoping they would finish their tours. I wrote up his story for a book on local veterans. Small world; I also knew his pilot and best pal who lived on the farm next to us in SK.
