Guys: This is not hard. O2 be O2 and usually in a small to medium size town there is usually only one shop in town that has the LOX facility, larger cities may have more depending upon demand. Everyone gets their gaseous from them, yes the medicos, the welders and the airport! Ever notice the little trailers with 5 green O2 bottles strapped to it? The, the bottles look surprisingly identical to the local welders’ bottles don’t they? And before anyone starts with the moisture wives tale, all O2 containers are required to be absolutely dry or be purged to insure dryness. Moisture, medical O2, is added to the supply line downstream from the O2 containers. The five year requirement for testing is done, guess where, the local welding shop who sends them to a regional hydro testing facility. I have been using “welder’s O2 for 13 years in my bottle and the welding shop has hydro tested it twice, price about $13 per refill and the same for the testing. If you are in the McKinney TX airport area there is a welding shop just of the airport entrance who will do it for free. However, for those who truly believe that aviation O2 is different, oh well, someone has to pay those high prices, it may as well be you.
Dan. 90% done and 90% to go on my -9A QB. Test fitted and clecoed the instrument panel today.
