OK, I finally got it: I can't wait to dig into his one: it has a tilt valve second stage, but the first stage is a diaphragm and uses the same plunger as the Scubas (DH's) and early Sportsways/Water Lungs! JB

That 1st stage is different, meaning...I've not seen a Scubair like that before, but I'm the newest diver here, so that makes sense. Looking forward to hearing more. Mark

Mark, I see you're quickly approaching 600-posts Good for you buddy, you're learning fast! I'll get some images up soon, but this one's gizzards are really different: Holy mother of pearl, the HP diaphragm is nearly 1/4" thick... Gunna go down to the hardware store this week and match up an o-ring for the valve seat: since I live in a big metro area, I know for certain they haven't been sitting around: cheap an' easy buddy, and no waiting for them to come in the mail either JB

I might be approching 600 online posts, but my dive log book only lists 60 actual dives. Which is about 56 more than I had thought a couple years ago when I had my heart attack...so yes I'm grateful for thos 56 dives. What I'm saying is...I'm a new diver, really don't know much of what I'm talking about, but get the gist of things and am learning. Mark

Hot d@mn, I love bein' CHEAP! This reg only cost me 34bux, an' that was with shipping! Would ya look at the size of that HP-diaphragm "I might be approching 600 online posts, but my dive log book only lists 60 actual dives.

Is that the same HP Seat set-up that is on the SCUBA Double Hose? This is why I'm looking forward to the Healthways Single Hose thread to be started. This Scubair is so different than the Scubair that I'm familiar with and own. The first stage is a totally different thing, not even close to the "round, streamlined" first stage I associate with the Scubair. So many things about the Healthways single hose reg series that I have wonders about. Mark

Mark, yes, the EXACT same part! Funny thing, the model numbers are both 1665!?!?!? OK, I've got it all back together: I've set the IP @ 90-psig... If you get one of these they need low-IP's because of the simple-tilt-valve; lower IP's make them easier to breathe. I'll be using the original second stage as my octo, and an early 1970's as my primary. I'll also, eventually, be putting another port in to run a BC... JB EDIT: I drilled out the hole in the reserve plate too: I refuse to deal with that feature... EDIT 2: I smeared that o-ring with grease and just shoved it back in: still good after all these years... yeah I know, I'm a danger to myself and others: 51/50

Jaybird,
Is the diaphragm so thick, perhaps, because there is no metal plate for the spring to sit on like most diaphragm regulators? Just a thought.

Jaybird, Is the diaphragm so thick, perhaps, because there is no metal plate for the spring to sit on like most diaphragm regulators? Just a thought. John DOH!I knew I forgot to shoot somethin' else... I should have gotten an image of the front and back of the diaphragm! No, it has a ummm, ahhh, kind of a nut and a bolt like the Sportways HP diaphragms. If you click through to my Flickr image and then magnify it, you can see what I'm talking about. Now that I'm thinking about it, it's probably as thick as the Dacor HP diaphragms on their DH's... JB

OK Mark, here ya go: These two regs have very little in common: the second stages look the same but work on two totally different principals. One is up stream and the other is down stream. The piston reg with the down stream valve had two exhaust valves in it as well... JB

Jaybird, Thanks for that explanation. That makes more sense for the diaphragm. Now, before you get too much going here, put one of the new silicone diaphragms into that very old, tilt valve second stage and take a few breaths off it. I think you'll see that even at that time, it was a pretty good regulator. I went from the Healthways original SCUBA regulator to a Healthways Scuba Star, the tilt valve version, when I first started diving, and it was a pretty good regulator at that time. Here's a photo of me with that regulator. This was a dive with the Salem Junior Aqua Club in Puget Sound, circa 1963 or so. John

Copy that Big John, but I'm way ahead of you though The piston Scubair I got from my friend Jim had an IDI diaphragm in it, so that's just went in. The piston version got the newer type diaphragm, but not the super IDI though. I need to get some silicone 23mm mushroom valves next: exhalation is a bit doggy... I've been popping the cover off of a few of my later models and using the IDI second stages, thus turning them into Scubamasters. JB

So...in a sense, the two Scubar regs. only share the name? This is why I'm looking forward to another HW thread. There is the Scubair, Scubair-J (which is easy to understand) then there is the Scubair-300. In my mind...the Scubair-300 looks more like a Scuba Star, with a sonic alarm. Even though it has the name "Scubair", in my eyes, it has more in common with the Scuba Star lineage... From what I can understand, there seems to be a lot of name changes and "over lappping" with names and styles of regs.
Oh, the joys of dyslexia, hope people can understand what I meant to say there. Mark
Edit. Looking at the "new to you" Scubair, there is no "Reserve/J-Valve" selector knob. See in my view...it has more in common with the Scuba Star (not taking in account the diaphragm 1st stage) and being "just a regular" regulator, with no "features" (Reserve/J-Valve selection, built in J-Valve, sonic alarm, etc.).
When I try to come up with Healthways single hose lineage in my mind...confusion reigns!!! LOL!!
Edited again to compensate for dyslexic mistakes.
