    Are there any images of that breathing set? Does it still exist?

    Some were in one of the magazines, from before they put everything on the web. I don't know how to find them. Bob's web site got taken down after trading standards took offence to all the non ce bits on it.

    His web site was http://www.rebreather.org.uk/ . Now defunct. You may be able to get some of the content from a wayback archive.

    Herewith a CGI attempt at a split-bag stabjacket-to-rebeather conversion, using only the 2 connections that a Buddy Commando stab-jacket has. The tubes contain one-way valves to keep the gas flowing the correct direction. The left (exhalent) side is inflated.

    Remember, do not try this at home, I was already tried, by highly skilled professionals
    Sorry, could not resiste... Suit based idea is much older than that! See this early FARTOX CCR design...

    Herewith another image of my 2-bag stabjacket-to-rebreather CGI Poser model. The men's compressed-air-powered underwater guns show where the inflation cylinders of the original stabjackets ended up in a waterfront workshop. Looks like that the area's port authority have something to hide underwater.

    I assumed that the term "stab-jacket" was some sort of inside joke sexual reference. My curiosity aroused, I read enough to see it was just a "BC" or buoyancy compensator. Sure you could convert it into a rebreather lung. I suppose in a pinch you could convert a vacuum cleaner bag or an enema bag also. But why? Rebreather lungs cost a good bit more than old BC's (a lot less if you find used ones) but that is not the pricey part of a rebreather. But what the heck, keep up the experiments.

    Stab-Jacket = Stabilising Jacket = BCD

    Rebreather lungs should/do cost peanuts (before retailers add 500%+ to the cost)

    Using a BCD as a lung is an Old idea, not necessarily a bad concept, they are worn close to the body/lungs and are ripe for adding ports and inflates too.

    Perhaps this topic is abit to much for the common user/white-goods type ECCR buyer who wouldn't be seen dead near a home builder

    IMO, if you were going to use a BCD you'd replace the bladder inside with multiple bags- (a couple of lungs and some kind of wing) afterall you don't need all the available volume, however it would be plumbing nightmare

    3 types of people in this cliche.
    1. Divers
    2. Builders
    3. Inventors

    Being one of the above is enough for most people, a few people manage to be two but being all three is the domain of a few genius/guru level individuals, if you're not sure you're #3, leave it to stuff made by #2's

    Here, "stab" is short for "stabilizer".

    About the size of a stab-jacket's bag, I was thinking of sewing down the middle to make a left bag and a right bag (and to avoid inflating the part across the midline behind his neck), to make a two-bag circuit: lungs to left bag to absorbent to right bag to lungs.

    This is in GCI art only: unfortunately I have stopped scuba diving and I have no workshop.
