My ADHD never gave me any extra powers. Except the power to get into hella trouble at school.

Okay, now I'm getting mad; Jaybird is "forcing" me to get a DivAir just to see and experience this unique regulator myself. (Not really mad, just very curious.) 😉

Phil, John, et al: I think the way to help you imagine the levers on this system is perhaps to think of it as a spine... When one part moves, EVERYTHING moves: you can't move just one part of your back, the whole thing moves! When you turn one of the adjusting screws, it is effecting the other lever in the linkage. I think this is why people get frustrated with these, or find them difficult to work on. Finding the lever height should be imagined maybe as them adjusted/moved up and down "en masse": I hope this makes sense?

I think this is why people get frustrated with these, or find them difficult to work on. Finding the lever height should be imagined maybe as them adjusted/moved up and down "en masse": I hope this makes sense? JB It does. You can see how all the levers are affected by both screws. A turn one one will change the geometry of all the levers. The next part of the mystery is to figure out the intricacies of the reserve valve, and how the adjustment on that affects the lp air metering. Oh, yeah. After JB solved the mystery of the lifty part, I'm bringing up that "other lever"! Speaking of metering, I am an ex auto mechanic who has worked on many a carburetion and fuel injection system. (I assure you that carburetion is correct even though the automated spell correction doesn't like it.) Metering air is of paramount importance. My question is about monkeying around with anything that will change the compression and tension of springs inside the hp valve. If you change things like springs, stacked heights of filters, etc., what effect does this have on air supply? This comes from pondering on the internals of my Divair. Filters are different, addition of an oring is different, and the spring appears to be lighter. Is this metering issue as important in the scuba regulator air supply as it is in fuel supply systems?

Pressuring is a strong word. Encouraging is a kinder and gentler term. I'm sure JB would never want to pressure you. Besides, you know you want one...... Hahahahahaha! Another one bites the dust!

Phil, if you PM me your e-mail, I can send you some stuff from Basic Scuba talking all about it...
Don't worry, I don't abuse people's e-mails: John, DD, Mark and Michael will attest to this fact!

Phil, That's why the "forcing" was in quotes. Jaybird knows me well. I like to get the old regulators to use, to find out not only how they tick, but how they perform underwater. Ya, I may be bidding on the next one around. John

I know it was in fun. I hope you find one, and enter "the elite collectors (club) who are the only ones who can claim ownership of a vintage Divair." I actually saw that on a site selling some Divair parts!

Okay, been doin' a lot of thinkin'; yeah that was that horrible noise you might have heard! I may have figured out an exhaust valve for this thing: I had to clear my hoses way too many times, so I for one am going to install one. What I have in mind will be bolted in using the bolts/screws that hold the top can/cover on. Phil; as a side note, would you please post an image of the clamp for holding on the diaphragm? Jaybird

Jaybird Jaybird, Does this mean that you have used your DivAir in the water? If so, describe the experience, if you would, please. By the way, some of the ol' timers may have put a mushroom exhaust disc/valve from a Hope-Page into the convolutions near the exhaust horn on the exhaust hose. 😀 John

I think the Gold-label gave you the most air, but only marginally between the three. I think one reason why the Divair worked so smooth is that the home made diaphragm is very thin, making it exceptionally sensitive for what it is. I didn't take it past six feet, so I expect the breathing characteristics will change at greater depth, but I was pleasantly surprised, as most people say it only breathes OK. I'd like to make a duckbill for it, or maybe something else, because the flooded exhaust hose is a bit bothersome while you're trying to compare three regulators...

I love this forum! Just the simple fact of the trouble and creativity put into getting a reg that a lot of people don't know about into the water again... That's all. Mark

Mark, it's people such as yourself that make this site what it is: this is a FAMILY SITE! This is the first, original and best vintage dive gear forum period: END LINE...

Thanks! I don't think I contribute much in terms of tech. and how to do things? I'm such a new diver to start with and in a perfect world should learn to dive with current modern gear in the first place. But I like it here. There is a "core cadre" that I like here. Mark
