.270 Ackley info wanted

[troy fairweather]

I would be interested to know just how much of any B52 is still original. Especially the structure. Aluminum spars and beams have to be replaced. I watched a program on the B52 and the vacuum tubes are all gone. The longevity of the B52 in service is something that is still debated. I really don't think it is a good thing. Costs for flying military aircraft are from $20,000 to $50,000 an hour, might have gone up. Airplanes, even civilian aircraft, are hugely expensive in terms of maintenance.

This has been around for over 200 years

Given that 15% of the structure is the original wood, is the USS Constitution, or something else? This frigate goes through a rebuild when it becomes obvious that it is in structural danger. It is one of the few wooden frigate still floating. Wood ships fall apart. The last the ship sailed was in 1997. When the ship is turned around, for weathering, it is towed.

If anyone believes steels from 1900 are all that great, present metallurgical analyses of the stuff. I have been looking for that information.

I was at mystic when they where refurbishing the constitution, a worker let me use a draw knife on one of the peaces of wood they were replacing. It was one of the ribs that hold the planks on the side. It was a cool thing for the guy to do even if it was just a few slivers of wood.

There has been some proof that metals change with age, seems most weaken tho they say the Japanese swords don't but never seen anyone test that. Every time I load for my old mausers I think to my self it's over 100 and no need to push it, one reason I have not done a 280ai yet. Like to find a commercial FN for that.

Age does not diminish quality or usability. If the quality was present when the item was originally manufactured it would be there many years later.

I wasn't really referring to the gun in question I was referring to any gun being over 100 years old. Again, if this particular gun was made of quality steel when it was manufactured the quality would still be there today regardless of it's age.

For example, the attached photo is of a Colt Model 1903 pocket pistol in 32 ACP. Production started in 1903 and ended in 1943, and this one was made prior to 1924 because it has the black grips. It's as good today as the day it was made and it's really fun to shoot. Eisenhower and Patton both carried them during WWII. This one went from my granddad to my dad and then to me. Very happy to have it.

There's a big difference from pre wwi metallurgy then 1955. Plus those bombers are inspected yearly.

Plus, there’s not a single 1955 airframe flying today and all the later G models that are flying have had substantial upgrades.

But other than that...

I remember seeing something the dc-3 I believe, is one of the longest planes in use. The one from the thing from another world movie. But I'd bet there's not to much original parts.

sounds like my great grandfather’s axe. I’ve only replaced the handle twice and the head once....
