I have the mid range on my royal set about 120 125. Thats plenty. It breathes absoloutly effortlessly at 125 feet! No draw, no sucking, all the air you need, just as if you were standing on the beach on a cool morning at sea level. You go tuning something beyond what it was designed to do, and somethings gotta give. They did it right the first time. Other than a duckbill and mouthpiece valves my royal is all original. I did flip over the lp seat and its still going strong after 42 years.

Chuck, right on!
No question about it, old Emile Gagnan had it right the first time. If you really want to breath easier at 70m buy a Nuyt suit(1 atm). Cheers, Michel A.

Yah, great idea.... then you could stick the old royal on ebay and the guy who has to have everything would buy it, then he can go nuts screwing with it the rest of his life.

If you just want to breathe easy for free, sit there and continue to read this thread. I think Im going to get my ground gripper shoes on, and run down and get a midrange pizza, thats where there is a big bulge in the middle, and it emits a gurgling noise. Then Im going on a diet!

OhOh... Gomez, I think this thread is deteriorating like the one where 'religion' was just brought up! Yep, never thought I'd see it, nitrogen narcossis at sea level and hell we're not even fighting over 'yellow' hoses with or without seams?!! "Seams" on stockings now you've got my attention...oh boy must be a full moon,better go to my shop and test some regs. Cheers, Michel A.

Since we are comparing the modern parts that will work with the Royal, will the conshelf spring block work in a Royal? I know they look differant, but if they are the same diameter, and length, it seems that they would work. I haven't actually compared them side by side, I was just wondering if someone knew.

Uh, I said I have experimented as high as 180 psi. I use a 140 psi which is not far from the range specified by USD and used in modern Titans using the same seat. I cannot find my Titan manual---where oh where could it be?? In any case information is for discussion and it can be disregarded or not as you wish. I am very happy with my latest results but the process I use to get what I get would take several pages to accurately describe as there is a bit more to it than simply jacking the IP up.
I am not sure, I would have to take measurements but I do think that the current yokes as being provided in the Phoenix kits and of current manufacture could have the threads machined out and the shoulder recessed. They are very much like the original heavy factory yoke on both of my RAMs so equippped.

Yes, the spring block, the springs, the seat, and the filter (with the added filter washer) are all direct replacement parts for ALL the diaphragm first stages of the same design as the RAM. The spring block doesn’t look the same and it is actually a bit longer, but it is design to fit and function as a direct replacement (with some minor improvements). The filter with the filter washer is design to basically the same thickness as the original filter with the metal ring around. The use of the filter washer allows the use of a standard flat filter (that can be obtained from many manufacturers). The Conshelf, the Titan, and several others use the same first stage design as the RAM and use the exact same internal parts (same part numbers) or functionally exact replacement parts.

The Royal was also advertised as having a , "Larger orifice for better flow at depth". It took me a while to find this "larger orifice" but I finally discovered that the nozzle "volcano" orifice is .110 inch, while the late model DA AquaMaster is .092 inch (it's interesting to note that the older dull chrome AquaMaster nozzles are even smaller at .080 inch).
Does anyone know what year the change was made from .080 to .092? I recently picked up a Pico address Da which is undoubtedly .080. Tomorrow I'll pick up my newest aquistion, a Waner address, reputedly from 1969. Would this one be .092? Just curious. Thanks

On the few DA nozzles that I checked, all the dull chrome ones were .080 and all the shiny chrome ones were .092. So the enlarged orifice must have been around 1963-64.

I now have the "new" DA in my posession. Compared to my Pico address DA's it does seem like its breaths a bit easier. It would make sense that it has a bigger orifice. As a bonus this reg has a longer yoke and an interesting hooka port adapter. Thanks again. Jim

Nemrod, very interesting. I like to keep my regs 'original as possible' so other yokes will not do, however in the 1970's USD certainly did not design a heavy yoke just for the RAM as this would have increased cost so there must be a yoke from another model USD(probably single hose) that is identical/interchangeable, I am trying to find out. My conshelf 12 has the same yoke and knob as my big-yoke round label royal. My conshelf 14's have threaded yokes.

Mannix, Thanks a bundle for that info, if your absolutely right it will make converting a round label RAM with the long yoke quite easy to make it appear as the last and best RAM of the seventies!
Thanks again, Michel A.

The Dacor valves with the metal wheels work fine with the heavy yokes and the banjos and they are relatively common. Some valves are thicker and may be a challenge, that is OK, the best heavy yoke RAM is the Phoenix and it does not need a banjo--lol.
Many modern valves are very thick, a heavy yoke and the standard USD style banjo are a challenge. It migh be possible to machine a recess in the yoke face to allow it to pull up further. Why does this matter, well, for your personal tanks you can use the Dacor valves or something similar but when you travel you will find aluminum 80s with Thermo brand/clone valves. In this case, you may or may not be able to install the banjo.
