Tanks

[chrpai]

Turn em around on Craigslist. 2 AL80's with fresh hydro and inspection. Someone will take them off your hands. It's hardly unethical because they are still fully street legal.

???????????????

Really?

Yes, really. I picked up a rental AL80 from the LDS the other day. Want to guess what it was? I dove that tank because frankly odds are if it's going to blow it's going to be when it's getting filled.

These tanks are still fully legal and there are shops that will still fill them. Properly screened these tanks aren't *THAT* horrible. Would I own one personally? No but there's a lot of perfectly fine diving gear that I wouldn't personally own.

I have one of those old tanks because it was thrown in at the last minute with some other used gear I bought (primarily to get the lead weights which are ridiculous @ $5+ / lb new around here). I checked (here, thanks SB!) and so did not bother wasting money getting the tank hydroed.

If I had bought them deliberately (as a green newbie) and had not been told of the fill issues I would have been severely pissed.

As a potential seller my good name is worth much more than that - regardless if the tanks are legal if they are not generally accepted for fills it is dishonest to sell them without disclosure.

That's a bit over the top to call me dishonest for selling a 6351 tank. Get your facts straight before jumping to that conclusion.

"I've read that 30,000,000 of these tanks circulated and of that there were 17 failures. That's 0.00006%."

I am not calling you dishonest, I do not even know you and you are not, as far as I am aware, misrepresenting anything you are selling.

I am also not jumping to any conclusions.

The relative safety of these tanks is not the relevant item for disclosure. The relative legality is not the relevant item. What is the relevant item is that most shops will currently not fill these tanks. To represent them as legal in a sale without disclosing this fact is dishonest by omission in my opinion.

With proper disclosure there would be no issue, also in my opinion.

It sure seemed like you were implying that I was dishost. Read your posts. FWIW. Where's your citation for "most shops won't fill these tanks"? AFAIK all of the shops in Austin will fill them. I know Scubaland and Dive World both do. I know Oak Hill Scuba list "Visual Plus" for their inspection process so I assume they do also.

Does Windy Point? I don't know. But I just covered 90% of Austin so it's not a blanket "no". It a case here and there of "no" and if that happens to be where you need to get your air, then yes, that can be a problem.

My point to the OP is was get your money back by selling them.

 

[gcarter]

If it is that easy to get them filled where the OP is then the OP has no issue, no need to sell them, so the discussion is moot. Based on what you are saying in your local market, it would be a moot point.

But.

If the OP can't get them filled locally then the same issue would face any local buyer, n'est-ce pas?

To OP: Is my cylinder made from the "bad" alloy aka AL6351?

That thread is the first thread in this forum. It is a sticky for a reason.

As for buying / selling cylinders made from AL6351, Caveat-Emptor. Just like anything scuba related, i.e. a Dacor reg.

Personally, I don't see why someone I just met should trust me or the person who slapped the sticker on my pre-1990 aluminum tank.

1990 is not always the correct answer...
stolen from:http://www.scubaboard.com/forums/ta...66-my-cylinder-made-bad-alloy-aka-al6351.html
All Walter Kidde DOT-3AL cylinders, of which production ceased in
January 1990, are made of alloy 6351-T6. Cliff Impact DOT-3AL cylinders
were made from alloy 6351-T6 before July 1990, at which time Cliff
Impact changed to alloy 6061-T6. Catalina Cylinders did not produce any
DOT-3AL cylinders from alloy 6351-T6; therefore, cylinders manufactured
by Catalina are not subject to this notice.
Until determined otherwise, any DOT-3AL or DOT-E 7235 cylinder
should be assumed to be made of alloy 6351-T6, if it was:
1. Manufactured by Luxfer USA before the applicable date listed in
the chart below;
2. Manufactured by Cliff-Impact before July 1990;
3. Manufactured by any other company in the United States,
excluding Catalina, before February 1990; or
4. Manufactured outside the United States.


Now lets focus on cylinders made by Luxfer as they are the most predominate scuba cylinder made with AL6351:

40 cu. ft....................................... S40 ........... mfg date 6-88

72 and 100 cu. ft........................... S72, S100 ... mfg date 8-87
80 cu. ft....................................... S80 ........... mfg date 1-88
80.8 cu. ft.................................... S80.8 ......... mfg date 5-87
