WTB LP72s

[Red Hat Jef]

I'm looking for a couple of the older LP72 2250psi steel tanks.

Prefer picking up/meeting in Orlando or Cave Country.

Tanks must be verified to not have the liner in them.

Oh you and your damn vinyl liner.

At the risk of sounding very hipster...Nothing wrong with vinyl as long as it's spinning and flat with little grooves!

Seriously I've heard of a few folks who managed to tumble the liner out of these tanks but it chews up equipment and takes a long long time. Not worth it!

Takes me 30 seconds to sand blast them clean. Takes me 6 months to break out the sand blaster and set it up. Yes, 2 weeks of tumbling 'might' clear it out, or maybe 3 weeks; not worth the effort that way. But if you get any with the liner, I'll trade one in hydro for two with liners.

You sound like a hipster just asking for some steel 72s.

What are you doing with them, anyway?

I have removed the vinyl liner in 6 tanks. 4 were a reddish brick color and 2 were some black stuff. Took 8 days of dry tumbling, 24 hours a day per tank. Used medium ceramic chips. The tumbler worked just fine (and still does). The chips came out in good shape too - a little smoother maybe than when they went in. But the tanks were as shiny as new ones and even the bottoms/crown were clear of the liner. I then used the tanks for 10 years or so before selling them - still in service as far as I know. Some were 1972 original hydro, but I don't remember the other original hydro dates. 74, comes to mind.

Wow! Good to know. I guess the folks I talked to didn't have the patience to stick it out for 8 days!

Gonna try leaving them in caves where the water likes to eat aluminum and see if they fare better.

Interesting. Find it hard to believe this would be the first such experiment, what has your research brought you?

Also, I have one you could use for the test. What do you want in it? 18/45?

Take a look on Jax craigslist. He has around 8 of them, but I they appeared to be lined, so i passed on them for now. Some looked stained/discolored, but there were a couple where the liner did not look to bad.
