"Now go back to sleep "
I have had a nightmare. I dreamed that Nemrod had passed across the river and St Peter, held up a hand and asked who goes there. I answered," It is I, Nemrod, Hunter of the Deep", ahhhh, he answered, YOUR the ONE!!!!! whose secret mod destroyed the vintage supply of Royal Aqua Masters. I sentence thee, Nemrod, Hunter of the Deep, 2 milienea in Purgatory!!!! Be gone with you.
I was then given a revelation, of huge turbo powered Sears Craftman rechageable drills and Home Depot mega drills with 34.5V super power and weighing more than a Subaru grinding away without mercy on all the Royal Aqua Masters in the land. A Horrid sight, how can I sleep? Nemrod

Hi
I don't know were you guys find all this variety of data on such a simple mechanism. Why make it breath better isn't diving vintage gear about diving the original equipment and using original methods. If you feel uncomfortable at depth just go out and purchase a new Mistral instead of trying to bring an old clunker up to modern standards. I've seen modifications on old gear take a divers breath away at depth so be care full.

Nemrod You have to stop drinking that coffee. Your dreams have entered the realm of surrealism. But they are a real hoot however. And by the way, your precision work on your regs is admirable. I only wish I had the talents of you and the other great technicians that frequent this board. Keep up the great work and better yet conversations. Must be a lot of these threads don't translate well into other languages. Or at least where it is so cold. But then winter is almost over. And I believe diamond is harder than corundum right? Can't wait until Sand Dog III. Double bubbles in the wine . . . makes a diver feel happy . . . all of the time. . . .

Ron Hearn It's not about feeling uncorfortable at depth, it's about tuning the mechanism to preform at it's best. Basicly like blueprinting an engine. I had posted this before, manufactures build machines to preform within design limits using parts that because of mass manufacturing tolarences vary somewhat. When all the parts are assembled together some may be slightly oversize, some may be slightly undersize and some may be exactly to design specifications. How the combination of parts work together determines how well the machine preforms. Most perform middle of the road, some better and some worse. If staying true to vintage is the objective than you would not use anything other than original parts. What happens when original parts are not avilable. I don't see where trying to build the best preforming regulator is contrary to vintage diving.

I can't see much tolerance control in a double hose regulator as there rather roughly made and most perform like crap even after a great technician rebuild. 30 feet on a rebuild is my limit and I don't go deeper cause I have a choice now to pick a better regulator were as back than they didn't.

Ron If that is your choise that is fine. I believe the majority of the vintage divers feel using these regulators to recreational depths is no particular issue. The general opinion is the AquaMaster is as reliable as any modern regulator and perhaps more so because of a total lack of O rings as a failure point and the inherent extremely low risk of freeze up in cold water

Ron I am not sure who has rebuilt your regulators, but I dove my Royal to 115' last summer on the Keystorm, a wreck in the St. Lawrence. It breathed as smoothly and fulfilled my demands as well as my annually tuned Scubapro G250. The only difference that I find with the doubles in breathability is due to position in the water, i.e. vertical vs horizontal vs upside down, etc. I would not hesitate to dive within any recreational limits with my double hoses, tuned to their best by members of this board and others. Oh and by the way so that you don't think that we are "crazy old antiques", most of us hold instructor/dive master ratings in various professional organizations, teach modern certifications daily, and yes, we do dive with modern computers. The double hose regulators are just great. Allan

Working on old regs is like working on old cars or antique airplanes. There is a style and simplicity that comes with these old regs that cannot be achieved with modern gear. Fine tuning equipment is part art and part mechanics. Even modern regs can be fine tuned to improve out of the box performance by someone with the appropriate knowledge and experience. I like to get optimal performance out of all my equipment. The performance is definitely there on the older regs especially with a Royal Aquamaser. There is almost no mechanical difference between a RAM and any modern regulator in the Aqualung line. The parts are even interchangeable for the most part. With the exception of the physics of regulator position when diving with a double hose there is virtually no quantifiable difference in performance between a Royal Aquamaster and a modern high end reg. The baseline of performance for a regulator under standard operating conditions has changed very little since the 70's. New regulators continue to offer improved performance only under extreme conditions. These conditions will likely never be outside of a lab and certainly not by the vast majority of experienced divers. As an interesting side note on extreme regulator performance check out the following: www.scubadiving.com/gear/regulators/scubalab_special_report%3a_muscle_regs/Look at the performance of the Aqualung Titan. This reg is the slightly updated version of the Conshelf XIV which is basically a single hose version of the RAM and it can achieve 75 Respiratory Minute Volume at a depth of 198 fsw. To put that in perspective an average diver can achieve 37.5 RMV for 1 min and a relaxed drift diver typically achieves 22RMV. This is the kind of extreme conditions it takes to truly differentiate between the performances of regs. It has become purely theoretical. The dependability of vintage regs is in no way inferior to modern regs. It can be argued that a well maintained vintage reg is more dependable than a modern reg based on the simplicity of the design. In a mistral for example there is almost nothing to fail due to the unsurpassed simplicity of the mechanism, and anyone who has spent any time at depth with a mistral will tell you there is no shortage of air delivery. All of my double hose regulators perform very well under a wide variety of conditions. I have had both of my Royal Aquamasters and one of my Spiro mistrals to a depth beyond 180' with no shortage of performance. I would hesitate to call them clunkers. But in the end it is most important no mater what equipment you are diving with to stay within your comfort zone and within your specific range of experience. Diving is after all for FUN -Ryan

Yo! simon Beans
instructor/dive master ratings in various professional organizations, teach modern certifications daily, and yes, we do dive with modern computers. The double hose regulators are just great.
You can all the plastic you want it dosn't make you any better of a diver either your comfortable or your not at depth . I didn't think Hellen Cooper at ABUCS allowed divers on her boat using vinatge gear. LOL

I dive annually with Helen, not vintage. However, I may the next time I am in Brockville. But seeing as how yo simon Beans is an American, there is another side of the river. I dove last summer with Mo Hunt who is actually older than me; and Moses and I were classmates. Anyway, if you don't want to dive with vintage gear. DON'T. Just leave us crazies alone. Actually, I am really a mild mannered person who has never said this to anyone. But in your case, why don't you bother people on SCUBA BOARD. Allan

Come on Simon I'm just playing with you. I dove the Jodrey last year with my Nemrod from Wayne Greens boat and made it to 175' on air and it felt like I was sucking a ball through a straw compared to my posiedon xstreme and narced to boot but hay! my 80 mix took me back to reality on deco. I had support on this dive and it proved that double hose regulators can be used at depth but they are nerve racking in deep, dark, chilly water. I don't participate on other boards cause they just argue. LOL

Ron, you do it your way, I do it my way and frankly I could care less what you think.
