Oxygen systems
We're installing a Mountain High Pulse Demand oxygen system with the kevlar tank in the RV-10. Does anyone have photos of an install like this?

I used this as a guide, but after some discussions with a couple of ME's at work, I just put some doublers on the bulkhead running across from the center support to the outsid bulk head. My tank is in the same location as Randy.

I don't know who that guy is but I would like him to plan, my panel! Seriously is he taking up any consulting right now. Thats pretty much what I had envisioned.
Now where is that money? I had it around here some where.

Battery next to O2 source?
This is EXTREMELY unwise.

HAZARD!!!
Installing the battery and oxygen tank this close to each other results in an extremely hazardous condition. We lost three astronauts in the Apollo 1 fire because of a small spark in an Oxygen environment. Everyone thought beforehand that it was a controlled and safe situation.
The really sad part is that six years before, the Soviets lost a cosmonaut in a ground test when an alcohol swab came into contact with a hot plate causing an intense fire. Because of the space race, they didn't tell the world about their tragedy.
Please reconsider the location of your battery and your Oxygen tank!!!

P.S. The more I think about this, the more concerned I get. Granted, airplanes have been flying around for years with O2 systems onboard. But if enough oxygen leaked from a line, valve or regulator and just one spark occurs in the O2 rich environment, then there is a problem. If you think aluminum won't burn, just consider that the FUEL of the Space Shuttle solid rocket boosters is ALUMINUM. That's why the solid rocket boosters' exhaust is so visibly bright. The experimental amateur built certificate of airworthiness gives us a lot of freedom, but with that freedom comes responsibility. If someone will show me a spam can that is certified with an oxygen system as close to the batteries as Mr. Marks' is, then I'll shut up.

I'm a heating contractor. I deal with natural gas, ignitors, etc.
At the moment, I'm not yet "freaking" out in regards to this installation.
Yes, there is some potential that a spark might exist, and the fact that an oxygen rich enviroment can make things burn faster. But we're certainly not talking aluminum dust as the flammable material; and quite frankly, I don't see much difference in moving the oxygen forward of the bulkhead or behind. Afterall, it's not like these bulkheads are totally sealed from the aft fuselage section.
Personally, I'd worry much more about my engine compartment going up in flames, than this installation.
P.S. --- I just realized that my 6A has it's battery in the cabin along with my fuel lines, aux. fuel pump and tank selector valve. My oxygen system is just behind the seat in the same cockpit. What about those batteries stuck on the firewall in the engine compartment?

Changing Gears
To change gears a bit, I'm interested in the installation on the other end of the system.
-- If you are or planning to use bulkhead style outlets, where are you mounting them? I plan on having both and overhead and a center console so there's lots of mounting possibilites but having never used O2 I don't know what is a practical solution. For example, I could easily mount outlets in the overhead, but would having O2 tubes hanging down when in use be a nuisance?
-- What kind of tubing (metal vs plastic) are you using to plumb the system from the tank to the outlets?

Bob, I had been pondering this a bit for my own 10, I keep looking at the baggage floor, tucked into the wedge shape area at the front where the rear seat back attaches. Mount horizontally, valve to the centerline of the AC.
Should stay out of the way, yet allow good access to the valve.
