How much is a 240cf inert gas tank worth

Not if you use progressively finer flappers. Of course, I'm only speaking in the hypothetical .................

What who does?

Steve

Nobody does nothing!!!

But I thought about it some more, and realized that I CAN do it on my lathe, if I wanted to, though of coursae I do not want to.

Of course. None of the honest people here would do or have done anything like that.

Except maybe me.

It does affect you if they are selling over the counter, to your customers. One of my suppliers got lots of calls from people wanting to buy tubes wholesale. Then they wanted to return them if they didn't fix their TV set. The Horizontal outputs and high power audio tubes could be damaged in a few seconds in a bad chassis.

It's an outdated business practice where they felt they spent too much time dealing with small customers. I never said it was a good idea. The local supplier who acted that way closed recently, leaving only one source.

They figured the other guys would tell them to go away, too. I ran into that in Destin Florida. Every place I went flat out refused to deal with anyone without a business license in that field. Since I was driving home on the weekends I just bought what I needed in Orlando. Some of the companies down here called their corporate offices after finding out that branches up there refused to sell to the TV station I was building.

When I was in the Industrial Electronics repair business, it usually lasted a few weeks to a year. :)

I used a hard stone - not a flap wheel.

I had to take a 3/4" to 1/2" hardened steel shank down for a boring head. I got two at a good price and got cutters with them. Sent me one and I turned down one of his that was 3/4". Both heads were 1/2" and all cutters were 1/2 except for this lone odd one. Likely a replacement.

That's been my experince in other parts of the country. 'We aren't in business for your convenience!' :(

I don't know what the terms are, but the local TSC Tractor Supply Co has a tank exchange program.. buy the tank there, get refills there (7 days/wk and evenings). The bottles aren't the massively huge industrial sizes, just small and medium sizes that are good for farm/home shop use.

There are similar national chain stores with product lines for agricultural-types that may also have welding gasses and supplies.

Thanks for the headsup. There is a TSC about

The Home Depot by me has Prax-Air cylinder exchange for Oxygen, acetylene, CO2 and Argon. The Tractor Supply across the highway also has their cylinder exchange. I haven't tried either since I have no issues at my local Airgas branch.

I will check at homedepot.com as soon as they come back on line. IIRC, they indicated stores that rented tools but I don't remember any that sold welding gas, in my vicinity.

I see that Praxair does not admit to the Dallas or Ft. Worth HD 'welding gas' outlets, for example:

Thanks, Pete.

The local outlet is listed as 'Praxair Healthcare Services' and is in a retail district. :(

In an unguarded moment, a store employee once told me that 'medical' 02 and 'welding' 02 comes from exactly the same source. Didn't surprise me somehow.

--Winston

And there is a small group of pilots that regularly refill their small O2 bottles from big welding cylinders.

Cool!

I peeked into a SCBA refill center once and saw that they placed water - filled cooling jackets around the empty cylinder to push it towards isothermalism (isothermality? isothermilitude?) during refill.

--Winston

No kidding. But the medical tanks are small and have different connectors.

OK, this is physics. :-) It will cool the cylinder, and plus the mass (inertia) of the water offers some protection if the cylinder pops. =:-O
