Here are two "new" regulators that I have been working on during the last couple of years. They are "new" only in the fact that they have never been seen before, but they use a 35 year old regulator body that is both two stage and balanced, with high and low pressure ports. The first one, in chrome, uses the Voit Trieste two stage body, a Mistral top box, a Nemrod bottom box, and Nemrod diaphragm. I used the Nemrod bottom box because it has the best exhaust valve of any two hose regulator - a large, two-inch diameter mushroom valve. The Nemrod diaphragm is more supple than the US Divers version, and greatly improves breathing. Everything was re-chromed to match.  The second regulator, which I have named the "Sea Lung", is something I am quite proud of. The box style was borrowed from the Voit 50 Fathom plastic model, of which I used as a pattern, and cast one out of aluminum. The raw casting was machined to fit the Voit Trieste body, and once again, I used the Nemrod diaphragm, which will interchange with a US Divers. The paint was just a quick spray job so that the regulator would be ready for the Wazee dive. But the aluminum boxes could be anodized, powder coated, or chromed as well, for a truly unique finish.   Both of these regulators breathe at less than a 1/2 inch of water pressure, they will supply plenty of air even down to 200 feet, and they have a very unique "look". I believe they will breathe as well as the new Mistral or even the Navy Mentor. Dan |

Wow, great job, Dan. One day I may try to hot rod one myself.

Dan,
Are you saying that these are for sale??? ;-) They look great, and have the advantages of the Trieste without the disadvantages.

Yeah! Is either of them going to go into production and sale? Perhaps I need to make a t shirt for them? ;D I still think that the other name u had was a better one.  |

what would the production costs be?

Dan,
Nice work!
I love the look of both of your regulators and really admire the craftsmanship that is obvious in both their performance and appearance.
Now if there was just an endless source of Trieste two stage bodies.... ;D
Thank you for sharing.

Jes,
The AMF Voit R-12 Titan II single hose regulator uses the same first stage as the Trieste, complete with the following parts:
19 85-490 Poppet Assembly
20 85-491 Spring
21 85-965 Housing, second stage relief
It doesn't have the housing assembly and demand lever, but it has all the "innards" to make a first stage, and most of the second stage, out of it. That means that there are a lot more parts available than we might have thought, as the Titan II was a popular single hose regulator. The seat is there in the Titan, and a conversion of the Titan to a Trieste II would be relatively easy with some creativity with other parts. The housing could probably be machined fairly easily to be the Trieste-type housing, and have the venturi enhanced at the same time.

Thanks, guys, for all the nice comments! I am working on my own foundry right now, and hope to be able to cast up some more of the aluminum housings (and hopefully some bronze ones as well). These can be machined for either the Trieste/Titan II body or for the Mistral. I would like to also find some more of the Trieste LP housings and levers so I can use the Titan II first stages, which are cheaper and much easier to find, as John R. pointed out above.
When I get these in production, I'll let everybody know.

Nope, I don't know about costs at this time.....

Dan,
Can you give us a report on how these two regs performed in the water? I assume that you had them in the water at Wazee. Did either of them take the deep dive?

John;
I've had the chrome one down to 100 ft and it breathes as well as the best Royal. The Sea Lung is the same regulator, only different boxes. We used it at Wazee down to about 40 ft. We also used it as one of our 'test' regulators, along with a USD Mistral, DA, Royal and I think a Spiro Mistral.

I was looking here: www.budgetcastingsupply.com/Metals.htmAnd it seems that the leaded brass, while having good machining characteristics, may be dangerous to your health. |
