Looks like I found the problem, I'm 99% certain that it's a blown head gasket on the 4th stage. That would perfectly account for the reading I'm getting, and I can feel (and have confirmed by spraying water) a very strong blast of air coming from that exact area. It's not a fitting, so a new...

I'm looking for somebody that can help get our Davey working correctly again. I believe that an untrained operator either fried the 4th stage output valve, or possibly the piston itself by letting it run at full pressure against a closed head for well over an hour. Any shop in a 300 mile...

Our backup/mobile compressor is a Davey, that until very recently would pump up to 4300 PSI when needed, and would fill 3500 psi without even breathing hard. Now it can barely hit 2800. Here's what happened, what I've done to try and fix it, and a request for help. It went off site to...

That's pretty much a done deal. Currently running 8 in a 8x1 configuration and manually working the cascade off the tank valves. I've got 8 more on hand, 4 are going to be dedicated for when I get to spend more of the owners money and get my continual blending Nitrox setup, and 4 are going for...

I want to thank everybody for the great info I'm getting. I apologize for not getting back sooner, but we are starting up the busy season here and I've been running like crazy getting the details attended to. I'll reply and expand on some of the posts coming up in the next day or so, but...

Bauer 18 CFM, Being a dive shop in TN it's going to be mainly batches from classes and quarry weekends, figure 30 AL 80's and about 6-10 HP 100's/ 120's on a Saturday night to turn around, same on a monday morning. 3 whips usually in use. Hope that helps. SMW

I am hoping to spend some more of the owners money this year to set up a continual blending rig where I can have 32% on tap (saving 4 bank bottles for it) and not have to PP Blend everything. I'm basing my decisions on the fact that there is a huge community experience of safely and...

Hey Gang, The shop I manage is going to be setting up a new workshop / fill station and I'd like some guidence on the best way to set up and configure our air bank. I'm going to have 12 4500psi tanks available to work with. I believe that they are "T" tanks, they are 52 inches appx...

Was she Mike Nelson's wife? :dork2: Steve

Yep, that's it. A 'Jean-Michel Cousteau Royal Regulator'. I knew that SB would have an answer for me. Thanks much. Steve

Hey Gang, Just picked this up (mainly for curiosity value) and am trying to figure out exactly what it is. It was billed as "US Divers / Aqualung" on ebay. Now I'll admit that the bottom of the first stage look a lot like a Conshelf, but as for the actual model both I and the owner of the...

Damn.... Now I've got that rig stuck in my mind and I want one. I see that DGX has the bands for 5.5 inch tanks, I've got a spare manifold and valve set, and I could always use some spare 40's for something (justifying like crazy) Steve

Contacts have been dutifully and carefully cleaned, and no change. And I do agree, it's a bit of a fidegety system. Funny, because the Finns developed the Nokia phones, they do know how to make bulletproof. Steve

I've got a helo2 (out of warranty) that has decided that it no longer wants to go into data-transfer mode. I know the cable is good since I've tested it with another Suunto computer on the same PC and it worked just fine. I've also tried an entirely different cable with the same results...

Tammy, Just heard about this from a diver at our shop. Thank you for sharing this, and good luck with your future life changes. I have not a doubt that you'll be even stronger after it's done. Steve

Nope, you're right. The fill station at the shop doesn't have a needle valve and a check valve, but same idea. I use the bank tank valve to control the flow. And you're right, if you open them (the bank bottles) up at the same time, you don't have a cascade. (as I had to educate some of my...

Thank you all for your comments, I'm learning a lot. Right now I've got a source for some 3/8th steel pipe 10 inches in diameter for a low cost. Now I know that in itself won't be enough to "contain" the blast if a tank lets go, but that's not the primary purpose. Let me give you more info...

Hey gang, The shop owner where I work want's to put some type of a containment system in place at the fill station. I'm thinking of something like a large wooden box full of sand, with individual sleeves for the tanks to slip into vertically. The sand layer would be tall enough to come to...

Hey Gang, POLL QUESTION AT TOP OF PAGE Need your help on settling a discussion on the best way to fill a scuba tank that I'm having with another person at the shop. Now we're not talking 'Wet vs Dry' or over pressurizing a tank. It's more about the mechanics. The setup we have is 8...

Be interesting to see what Aqualung does now, I've heard that at least initially they will be doing something with Oceanic for dive computers but it's going to leave a big hole in their product line. Doesn't affect the shop I'm with, we're both Aqualung and Huish (Atomic, BARE, Liquidvision...
