Disposable O2 Bottle Manual Add Valve Contest?

Yankee Rebel

i had an idea... since folks here like to do it themselves and generally tinker, and the nice lil red disposable O2 bottles have been used to great success by many...............................

i thought it might be neat to see what sorts of ideas we could all come up with for simple and effective homebuilt DIY Manual add valves for these things, not to mention some good fun.

im also working on one myself right now, need to run back to OSH for a new bottle of O2... bastards sold me one that only had about 8 liters of O2 in it... im not happy about that.. but thought id mention it as a warning to anyone that may use these bottles for personal consumption. back on topic though.....

the winnwe will win... ohh i dunno.. lets see... how about a slightly used $20 bill right out of my pocket?

any interest?

Rules will be simple, and to be announced if theres any interest.

Hi Yankee Rebel

Been done...see Dr Bobs Feor site....

CCO2

Any homebuilder who has not looked at this site is really missing a lot of fun and some great ideas.

Dr Bob used to run the rebreather parties at DEMA when I can assure you there were not that many diving homebuilts.

Quite frankly, I still think his Full CCR FEOR is the simplest best operating unit out there...and than includes my stuff. I was diving it in Honduras with Dr. Bob and loved it.

So....

Send him the 20 bucks....as he says...he's a starving country dentist.

Tom,

I've scoured Dr. Bob's page for that push button info, but I don't think it's there anymore. Cstmwrks had mentioned it, too. A while back I wanted to see the method that was used to make the push-button system but I couldn't find it. Still can't.

I`ve marvelled myself at the feor o2 rebreather, what actually is the red cylinder/o2 push button add valve from ?

The little red cylinder is from a little welding kit that uses disposable gas supplies. The pushbutton, I think, it homebuilt.

I thought they looked familiar, like a small mig welder tank.
Are the tanks refillable then ?
O2 cleaning ?

Tom!

youre right about Dr. Bob's push to add valve on one hand.. but on the other hand.. i have to disagree with you.

it IS a very well done and nice looking button... he has something really nice there, and id LOVE to see how it goes together and works. ive scoured his website until my eyes couldnt see worth a crap, LITERALLY, ive Googled until my Googler needs one of those miracle blue pills from Pfizer (sp?) to keep going... ive looked and looked.. and the only pics i have saw with it are a couple on his site, and they offer absolutely no detail. just a neat looking brass push to add valve on a red disposable 31 liter common everyday run of the mill garden variety hardware store bought Oxy cylinder.

it DOES look impressive and it appears to be the perfect ticket for that use.. IF the maker has a LATHE... and there lies the problem with it. the maker/user has to have a lathe to make one. most of us do not have lathes, i know i dont. if i DID have one.. id not know how to use the thing properly anyways so i might as well not have one to begin with. i could learn, and i do want to learn.. but thats down the road. so the lathe aspect puts a homebuilders part that deserves to go into the Incredible category, and puts it right into the crapper. thats not entirely true, but im tired... its been a long day, my wife is pergnant and my little boy has been pissy, and my eloquence went with the unreasonable emotional bitching at the drive thru employee at the local Jack In The Box over a misunderstanding because he didnt know wtf a "low carb" sandwich was (gestational diabetes)... too much info.. but you know where im coming from i hope.

one of the "rules" for the contest i proposed was that it had to be built with COMMON everyday hand tools. nothing more complex than a small table top drill press, or a hand drill, cordless drill.. die grinder, dremel, file, hacksaw, hammer, angle grinder, bench grinder, tin snips, etc sort of basic hand tools. the hightech stuff being the dremel type rotary tools, and a drill motor or a drill press. NO "drill press cum milling machine" bolt on tables allowed.

i wanted to see what folks could come up with for the lowtech crowd, as i believe EVERYONE that wants to dive a rebreather, has the brains, ability, and drive to actually build their own... SHOULD dive a rebreather if they can understand it well enough and take responsibility enough for themselves not to blame anyone else if they die. personal responsibility i know is lost in the modern world. but i retain some hope for the world when i look at rebreather divers..
your hotwater bottle rig has LONG been a personal favorite of mine, its simlicity is perfection. its low tech, and it works.
one of the reasons for the disposable O2 bottle aspect was that sometimes its a bit of a real PITA to get an O2 fill... sure it can be done.. its expensive to go down. buy or rent an H bottle, get the adapter or make one up to fill med bottles off it, pay for the fill on that H, and then have a big bottle of O2 on hand to get diminishing pressures on over time. for the high volume diver.. they already go that route.. but for the occassional diver or recreational o2 diver, its simpler and much more cost efficient to spend $5 and buy a 31liter bottle of o2 when they want to take a swim. sure the duration sucks compared to a M6 or M9 bottle.. but it is what it is. simple and convenient and almost hassle free.

i really was hoping thered be atleast SOME interest in this.. but i am encouraged that there is interest in how the good Doctor made and built his valve. maybe some real good will come out of this thread after all.

Best Regards
Yankee Rebel

p.s. i can see how a common needlevalve from a mapp o2 brazing torch set that uses those bottles could be used for an O2 supply valve.. albiet probly slow.. and i can see how one can be modified into a push to add.. but that takes what is a $50 kit.. just to hack up and use one part... and discard the rest.. maybe im still missing something though.

Why don't ya'll just write Bob and ask?

And the constant macho struggle between members

WARM CALIFORNIA SUN

There is the secret handshake and the required midnight sneak into hotel pools with your rebreather initiation at DEMA. Hint, If you don't have something as easy to use as a FEOR, a RGU, or a Cressi....getting out before management has shown the cops where the pool is a struggle. This ain't a contest for a Meg, an Inspiration, a Dolphin, or a Prism.

I wrote and asked him yesterday and have not received an answer yet....He actually had to improvise one without his lathe in Tahiti a couple of years ago and sent me an email with the pics....I cannot find the email or the pics.

On another front, I think Customworks Bill has made one also.
