I actually just ordered another Sea-Vue for very cheap yesterday for another reg. I have. I want to hang onto this one. These are fairly easy to find. Mark

I opened up the 2nd stage and other than the diaphragm that is like a Dorito and is broken, every thing else is clean and no leaks. I hooked it up to a tank again and put my IP Gauge on it. No leaks and 100 PSI. Unless I dive it and find something wrong, I am going to make a new 2nd stage diaphragm and leave it as is. If it is not broke...
As for the 1st stage, I'm pretty sure it is very similar to a Scuba Star, Deep Star, Aquarius, etc. If it fails it's pool test dive then I'll go from there, but think I'm leaving it as is now. Mark

Mark,
You didn't tell us the tank pressure that you were using for this test. The reason I say this is that at high tank pressure, a piston first stage will have a higher interstage pressure than at low tank pressure. I feel that if you are getting 100 psig at 500 psig for the tank, you are okay. But if you are getting 100 psig gauge pressure on a full tank, with an unbalanced piston first stage, that may descend to a critical level, say 80 psig, which may leave you hurting for air.

John, Mark, that is right about where it should be for this type of first stage: remember these ain't adjustable without shims... Again, these have a flat valve-seat, not sharp or knife edged like modern regulators: I still can't figure out why the (expletive deleted) they designed them like that?
John brings up a good point though: adjust the second stage with a low tank!

It was on a full tank. Mark

It was on a full tank. Mark Mark, In that case, it would be good to at least put it on a tank with 500 psig and see what the interstage pressure reads. Unbalanced piston first stages have a drop in the interstage pressure as the tank pressure drops. Anything below 100 psig would probably compromise the performance of this regulator's second stage. You would have to open the first stage up to see whether the interstage pressure could be adjusted, or if it is dependent only on the spring tension (many lower-priced piston first stages of that era were not adjustable). If no provision is made for adjusting the interstage pressure, you can try thin stainless steel washers that can go under the spring to increase the interstage pressure. Scubapro used to have these for their regulators, and it's possible that they could fit for the Voit first stage too. Each of the Scubapro washers was said to raise the interstage pressure ~2.5 psig. This may or may not be the same for a Voit first stage though. John

Looks like I got a replacement diaphragm sorted out for this one. After a series of failures and torn rubber, I found that the current Aqua-Lung diaphragms have a centre section that "just slides out"...can't explain it with my dyslexic brain, but no drama was involved.
Have the "perferated" section being glued in overnight. Mark

I got to take this underwater for a half hour on July 4. This is a great little reg!!! No drama at all!, just a fun little regulator!!! Looking forward to diving it again! Mark

The Titan took its second dive today and did just fine. Mark
