Double hose modifications

Well, I decided to rebuild one of my Healthways single stage regulators recently, and add a few improvements in while I was at it. The air from the Healthways comes out of the valve body at a 90 degree angle to the lengthwise direction of the lever assembly. I first had a machine shop drill and tap a new set of holes which would place the air flow towards the inhalation port. I then took a 1.5 inch washer, drilled a set of mounting holes and used a dremel to cut a flap, which I bent upwards slightly to block the air on the opposite side of the valve body and direct the stream into the hose, hopefully creating a nice venturi effect.
