I've been planning this project for a while and the only things that I could think of to make a chamber were glass, wood, and metal. I considered a 50 gallon drum and welding some angle iron together to build a box then filling the sides with plywood and glass or plexey glass. The Oxygen tank and regulator all the fittings are redly avalible. The problems that I was faced with was the price of the glass and other materials. I wouldn't want to be in an inclosed box for a period of about an hour. Next problem was what are you going to do if you run out of oxygen. Where is the safty measures for getting out. No glass wasn't an option so the 50 gallon drum was out. Problem with the glass is I don't want to be in something that if something goes wrong I won't be able to get out. So here's what I have came up with so far. I got part of the info from a portable HBO. Take 1 piece of 3/4 inch plywood about 7 feet long and about 4 feet wide. That is your base. You'll be connecting the oxygen reglators in to that base with the inlet going into the chamber. Next part is so simple it even amazed me when I came up with it. Take 4 pieces of 2x4 and cut them so that you have a frame that is 7 feet by 4 feet and connect them together. Mount them on hinges connected to the 7x4 piece of plywood. You want the two woods to meet together so don't mount the hinges together. You'll have to figure out some way to clamp the 2x4 frame to the plywood and hold it shut so that it will hold 5 or more pounds of pressure. I have't worked on that one yet. You'll have to do that next because you'll need it to press the silicone in to position. Wax the 2x4 frame then run a bead of clear silicone around the plywood. This will keep the frame from sticking to the plywood. Close the frame on the silicone, lock it down and let it dry. When your done you'll have a air tight silicone rubber seal. Ok now you have the door, the base, and the way to get the pressure of the oxygen. Last is the best. You need a THICK sheet of clear plastic about 12-14 feet long and 8-10 feet wide. Remove the hinges from the 2x4 frame, run a bead of silicone around the outside of the 2x4 frame then tack the plastic to the outsides of the 2x4 frame. After that you'll need to add a wooden strip to hold the plastic in place. Now you have the makings of a HBO chamber with a door. You still need to mount a resperator hole some where and a resperator tube out. That way if you go to sleep and run out of oxygen you will still have in comming air. The cute thing is if you run out of air, door is jammed, you don't have to break a glass or a sweat. Take your pocket knife and cut the plastic. :} Oh yea mount an emergency knife in on the base.
