Yeh! I still need me a, bright orange, '57 Chevy with flames on the sides ... ok, I'm dreaming again. That's not vintage; everyone was driving them when I was in high school (well, that could afford them, which excluded me). Vintage is like Model T Fords!

Vintage in the auto world might be a Model T but Period for Vintage Scuba would be the 57 Chevy, a muscle car or a nice VW window bus with cloth top and surf rack. Vintage when used as an adjective to scuba means an era or period, I thought anyways.
I was not meaning that I was upset with the "5" people, no, not at all, just stating that a market of 5 is not very deep if they quit bidding. I am not bidding on anything now because as much as I want a nice Navy Voit I simply cannot afford one at a 1,000 dollar price, sooner or later if it was meant to be I will get one, if not, oh well. No, I think fair bidding is just that and I certainly don't mind, at least they are going to good homes. There is more interest suddently from noobs to the community or such because we have collectively been talking this stuff up--so we are our own worst enemy when it comes to ebay---lol. I am happy to see the good prices and interest. Good prices often prod loose more vintage era equipment from dusty shelves and dingy closets. Heck, at least several of the fellows bring the stuff to vintage events and dive it so we can drool over it--that is part of the fun of it all. ;D

Sustained Load Cracking, that was what I was trying to remember yesterday. Luis, thanks for the explainations. I appreciate this amount of detail. My hope is to keep my UDS-1 going, but if worst comes to worst, I would probably trade them for some new cylinders from the LDS, who's owner does collect old gear (which she doesn't dive). At one point, I'd like to set up a set of small doubles, much like the jump tanks we had in the USAF. Those tanks were twin 42s, made from twenty-man life raft bottles that we had tapped to a 1/2 inch tapered thread for scuba tanks. They were very nice, and could be used with double hose regulators too. Here's a photo of them: I had to have those tanks drilled, as the threads were no longer stable. The USAF got rid of theirs too. But in the 1960-1980s, they were used as our jump tanks, and sometimes traded to the US Navy. The Navy divers did not like the extremely heavy doubles they had, and these filled a need when we traded them. But, I would like to keep the UDS-1 going as long as possible. John I did find that one of the two manufacturers of eddy current testing (I believe Visual Eddy) has made some 1 inch probes for the beverage cylinders industries. They are very hard to come by, but I am aware of at least two places you can send your tanks to be hydro and eddy tested. Mark Gresham (manager from PSI) recommended: City Carbonic Phone: 1-800-286-4291 Talk to Amy Bruecks, she is the manager at City Carbonic. Mark also offered that you can send them directly to him for visual eddy testing and he can have them hydro tested at one of his local hydro facilities he work with. www.psicylinders.com/Mark Gresham 16932 Woodinville-Redmond Road, Suite A210 Woodinville, WA 98072 Voice 425-398-4300 Mark is very vintage tank friendly, they are in the business of teaching how to inspect and recertify (good safe) tanks, not to take perfectly good tanks out of service. Obviously this is not very convenient and the shipping cost for the three tanks is going to be a pain. But, at least it gives you a couple of options and if you search there is some hope of finding someone closer that has the proper equipment and is qualified. I also did not ask anything about prices, but my guess is that it would be lower than many LDS around the country. In any case if you are going to hydro and eddy test three tanks, it is not going to be cheep. Good luck If you do talk to Mark, tell him that I sent you.

By the way, the UDS-1 tanks are not 1" threads (1" x 11.5 NPS) they are 1.250 x 12 UNF-2B
Yes, I have a set that needs hydro and eddy current testing too.

Thanks for the link Luis. I will give Mark a call later today.
