Will the DAAM fit in the pre cut Trieste cans? Just wondering. Might need it for a future project. The locking mechanism with the screw ring on the Trieste looks the same as the one on the DAAM.

If you are talking about the plastic cans from the Scuba Museum, the answer is yes and no. The hole is the correct diameter so it will "fit" but the DAAM body is designed for an off center hole. The hole in those cans is dead center. You can install the body but it is not in the correct alignment for a DAAM.

TD TD, I think the problem would be that the nozzle for the DA Aquamaster will not be close to the inhaling horn, and that could affect the Venturi, resulting in somewhat higher breathing effort.

John What about with an HPR or a modification to the Venturi ports? Jut thinking. I'm thinking of using it for a remote chest mounted second stage. TD

The offset allows the horseshoe lever to center on the diaphragm plate, as well as to position the venturi close to the intake horn. It might work to use a single stage set of FX cans (also cheaper!), but you'd have to cut the big hole over the small hole. Don't really know if that would measure out correctly. A set with no hole would be the best way to go. Ask Rob if he knows of anyone doing this!
Also, there are locating tabs on the DA cans and detents on the valve body. This isn't crucial, but one would have to be sure nothing moves over time by making a register mark.

I'd like to build a DAAM (What??) Yes, by buying all the parts like the valve body and piecing it all together. It might be cheaper to buy the individual parts like the HPR then buying a stock DAAM and modifying it. That's where the FX Cans come in. Just a thought for a different way of doing things. Like gun owners say "Built, not bought!" TD

The Mistral orifice is, according to Fred Roberts, the best-designed orifice of any regulator. Just another thought. John

John Probably because it would require a redesign of the valve body to accommodate the venturi nozzle length. The second stage is right up in the intake horn. Very little room for the Mistral type venturi. I suppose the nozzle could have extended up into the horn, but that would've changed the venturi's characteristics. I wonder if the old StreamAir bolt-head venturi would have improved things?

All it would take is enlarging the primary hole to accept a Mistral orifice, then closing off the other two holes. John

That would be with the Trieste-cut cans, which won't work. You still have the lever centering problem. If you offset the valve in the FX cans to center the levers on the diaphragm plate, the second stage is right up in the intake horn.

I checked the DA cans, the offset is about 0.550 inches. It will affect venturi as well as not centering the levers and while not really critical, will offset the cans on the tank. You can't cut the Faux FX cans off center because the cans have a deep depression in the center. That depression is just barely large enough in diameter to be cut out the fit the Trieste body. I know because I am the one who cuts the cans for Rob. There is no need to increase the DA/RAM venturi, properly set up (or better yet with the HPR) it is about as effective as you can make it before it becomes unstable. You can get too much of a good thing. Based on the AK, I suspect you can easily push a HPR over the edge fairly easily even in standard cans with a little work. If you add one of the VDH DSV's you could get away with a bit hotter venturi since it is designed to provide some negative feedback to the venturi.

Will the DAAM fit in the pre cut Trieste cans? Just wondering. Might need it for a future project. The locking mechanism with the screw ring on the Trieste looks the same as the one on the DAAM. TD Why don’t you just get a Trieste and stick it in those cans? I did and it works great.

There was a song I listened to a lot as a teenager in the 80s called "The Bottom Line" from B.A.D and that's what it boils down to. I can't afford a Trieste at their prices. Unless someone has one they would be interested in selling *wink wink* TD
