if you own your own aircraft.. and a hanger to keep it in.. and do a lot of

check out the local gas supply sources.. our glider club keeps two tanks
on hand, one full, and one partly full, we swap them out one at a time, one
tank we own, one we rent ($9/month)..

to get a full tank is $50 at swap out, and it will fill that tank of yours
a few times... and if you get short changed on a fillup, it's your doing..

Good GAWD, I've been paying a tad over $20 USD for a full size tank
exchange. I lease them. No hassles of testing. Just take in when I
need gas. I think it was around a $100 for the 10 year lease. I
don't know if I could still find the papers.

Just be careful when working with pressures that high. That stuff is
dangerous. Don't get it near any oil and don't even leave body oil on
connections. I've plumbed many a manifold with up to 8 high pressure
tanks and not lost one yet. Although not set up now, I used 1/4 SS
tubing for the connections when filling tanks. Nothing larger.

Santa's wife has decided that she would prefer that I fly with oxygen
even below 12.5K and especially at night. So I've been given a tank et
al. I was shocked today when I had it filled at Merucry Air. It is a
415 L size D tank. Because the pressure in their filling tanks were a
bit low, they could only fill my new tank to 1700 lbs, not to a fully
topped off level of 2000 lbs.
They charged me $40 flat fee..... a discount they said because it is a
small cylinder. That seem really steep to me.

Is this about right fur filling an O2 tank. I've heard that it is OK to
have the tank filled at other places such as with medical O2 or welding
O2. Is that OK?
