...I remember a story, perhaps from somebody on this list, where a
person had a pair of tanks from Nazi Germany that they still used. I
recall that the swastika had been crudely "disguised" by adding more
lines, but was still discernable and the tanks were still in use.
I have a small set of 40cu ft tanks myself. (knee highs, in a little
roll around cart) For general blue-wrench work around the shop, they
last a long time. If I do a lot of cutting the oxygen bottle does run
out though. I just use the local swap program, show up at a shop, walk
in walk out with a filled bottle.
I didn't sign up for the service, I just started using it. I was
given the bottles from my dad who ran out of uses for them. He probably
had them at least 15 years before they got to me.
