Your also stupid! (myself included!) This here be the most cost effective alternative to huka diving. Modernizing refinements include use of a plastic five gallon bucket and a plexiglass window. The thick kind you see at home depot Just heat gently with a heat gun, once the plastic is soft enough, put a bend in it to match the bucket's shape. The best way to attach this is with epoxy resin. Use lots to ensure a good seal and strong bond (wouldn't want a blowout at 30 feet!) When you cut the window hole be sure the holes for the handle are lined up with the front and back of the helmet and remove the handle. The top valve should be replaced with a pvc "T" fitting with the top of the tee on the inside of the bucket. The bottom of the tee is fed through a tight fitting hole in the top of the bucket. A series of pvc fittings can be assembled to adapt the fitting to a 1/2" compressed air fitting (or what ever you have laying around, think new and clean though.) This tee fitting is bonded in place using fiberglass resin. No fiberglass, just the resin and hardener. Goop it on thick to ensure a good seal and strong bond (just like you did with the window.) Cut a shallow half moon shape on both sides of the bucket rim to make the whole thing ride more comfortable like on the shoulders. Use water pipe insulating foam to pad the rim of the bucket and use the holes for the original handle (removed,) to tie the thing on to your head. All that air will try to lift it off your head if you dont tie it on real good. The most comfortable way is to put on a belt real tight and run some clothesline through the handle holes and around the belt (also good and tight.) If the lashing isn't tight enough the air will lift the helmet hard enought to take out all the slack and leave you hanging underneath without any air. To the top compressed air adapter run air hose to the highest volume air compressor you can get to the dock or onto the boat. For safety tie a life line around your waste(you want yourself to be pulled out not the helmet!) and use only quick release weights (or use the sack of rocks so you can let go in a hurry.) Always have a crew topside to pull you out if things go wrong. The exhaust valve is not necissary as the excess air will escape from around the rim of the bucket at the bottom(holes in the bucket are a bad thing as the water will fill up to that point. Again only you are responsible if this dont work as i'm sayin now this is not a safe toy. If you do the following your not just crazy. Your also stupid! (myself included!)

Have made one of these HMH ( Home Made Helmets ) myself, and the addition of refer oil in the bicycle pumps in lieu of tool oil, it works great at depths of 75'. I just get a little headache from the carbon seals in the cycle pumps degrading.....even got rid of my Miller 400, to build this rig. Great stuff :-) - Mike * To air is human, to HeO2 is divine.
