oh, don't start Mac the nice guy stuff. as I am a biker when I am not a pirate, or a wild native american, or anything but a nice guy... No nice guy here....

I have no idea how to search any places near you.. Thar's a pretty good reason fer that, since I live 1/2 the world away.
I want you on o2 Right Now. I want everyone here on o2 right now..
And I don't care how anyone gets it.... Poly tics and doctors may not be in anyone's best interest.. I don't give a rats a$$ about either one of those types. A CH has nothing to do with power, or anything else it is pure unadulterated pain.
Maybe if one can come by a doctor who knows something worth the knowing, that is a different story, but many doctors don't have the first clue. Not saying doctors are totally clueless, but more that this problem isn't in their list of tricks.
What I am saying is we who share CH probably know how best to deal with ch, and the safest way is o2.
Since it isn't likely that anyone is going to fall asleep at KIP 10 then there is no danger of breathing too much o2.
The only real danger as I see things is FIRES... You take the slightest fire and add o2 and you get a real bad fire.
Since o2 can soak into things like long hair, clothing, bed clothing, and the like you must be sure no fires will get started,
O2 in a room heated with gas heaters, kerosene heaters, oil lamps and the like is a sin. So is lighting up a ciggy butt, and or going onto a basement/cellar where there is a gas water heater.
Or any other place with fire. Still some how at a kip 10 I don't see anyone setting up the barbi for ribs..
I KNOW what ch is... I know if you can break it once it will change.. The change won't exactly be welcome, but the break will be.
Once you get that break, and discover what the change is, you can learn to move with it, and so change the Dance.
Most people think of the dance as the odd things they do in a bad ch. I do, but I also see the dance as ways you move life to avoid and abort the ch.
A part of my dance is to move my life habits, so I either don't get hit, or take hits when I am mad enough..
I KNOW all anyone needs is 1/2 a welding kits, unless they also want to weld and braze.
I just don't care about what is and what isn't legal. Not when it comes to CH anyway. It isn't like steraling a car, or robbing a bank. You are not doing anything to anyone but you.
And all you are doing to you with o2 is killing some very real pain. o2 won't make you crazy, or even cause any after effects..
Well with in 30 minutes you will be nearly as good as you ever were, and then be able to function.
I KNOW that even though I dwell very rural, that with in 1 hours drive in any direction I can get a lease and a bottle of o2. I KNOW that with in that same distance I can find 3 discount tool supply houses for lesser expensive oxy actelene set up, and closer I can get sets at auto part stores..
The work comes in finding a single regulator with atleast 6 feet of single hose for me. So the costs are reduced for exactly what is needed.
Not much sence in getting another reg or bottle for welding if you don't plan to weld angel winds like Tom Hanks found in the Castaway.
On the other hand, so what if you get torch tips, a red line made to the green line and just don't use it....
I have no mask, but Marc clued me in to the mask isn't always used by ch'ers anyway and the kit from here also comes with a mouth piece. Evidently the mask can hurt someone with a raw jaw..
Maybe I would gain bennies myself if I went and bought a swimming snorkel, and stuffed it on my torch grip.
Then I could bite down breath in and let go to breath out. Might improve the quailty of o2 and it sure would be warmer that what ever below 0 it happens to be in winter...
Last night I was frustrated and so thinking in text... When I do that the sentances come out the way my mind works, sort of scattered..
I got hurt real bad back in 87, and ever since find alternate ways to get what I need.. When I need a part I thing about that part, then I think about what else looks like that part.
Then I go find the freest thing I can to make what ever I need a done deal.
There is no way around a big tank of o2. A regulator is a real good idea, but can be done with out.. Going with out means there is a risl of blowing o2 at 2,000 psi into your lungs Right Now, and I that would kill. Still it can be done.
Maybe next most primitive would be to slam clear tubing on the tank threads.. That gets you a distance and will lower psi somewhat.. Then you could tie a big thicker than a trash bag to the hose, and add another tubing to that bag. Then the bag would fill up and you could see it. Breathing off the bag with some psi still blowing in your face..
I can dream up all sorts of things from that point and so far the costs are the lease, and some hardware store tubings..
The thing is, this way is wastefull.
My torches have apx 60 feet of line so I can cut steel away from the wooden barn, with less chance to burn the barn down.
I don't waste a bit of the o2. It6 runs out of the tank thru a regulator, thru that 60 feet of lines, to the grip. The grip has a knob I open and close as i breath.
After my walk to test the ch level, I return to the barn and breath more 'just to be sure'. Then I close the tank off, and breath the last in the 60 feet of hose....
45 psi is about the same feeling as on riding my Kawii Nomad at 85 mph.... maybe a little less.
So 'we' want lots of flow that won't blow us up.
