    Vintage DIY.

    Another common problem is the gasket not being located properly during assembly. Both the nylon and phenolic ones are prone to this and if tightened too much before this is corrected will damage them. Depending on how you assemble the parts, this can be easy to do and miss. I do not like placing...

    Mistral - To Grind, or Not to Grind; that is the question

    Hard seats have either a small radius or sharp edge. This reduces the amount of force necessary to seal the connection and allows the soft seat to take a set better/easier. In the case of a Mistral and most other USD regs, the hard seat is a dull radius. If you grind/polish it ,it becomes a...

    Mistral - To Grind, or Not to Grind; that is the question

    Put the Dremel tool down and slowly back away! Any power tool is too brute force for this job, it's way too easy to do more damage than you started out with . 800-1000 wet/dry sand paper on the end of a dowel is about as brute force as you want to go. A few turns of the dowel and then inspect...

    75 or 90

    Yea tbone you should know better. :) The bottom line is at higher differential pressures the oring durometer needs to be harder to help avoid extrusion. Softer ones may work but the tolerances between the parts have to be closer to get away with the softer material.

    For Sale US Divers Single Stage Regulator

    Your price is in the ball park, maybe another $20-30. If you have evidence of your story (not questioning it ) like a letter from JC about it, you could likely get more. Now it it were me, esp with my personal story to go with it, I would rebuild it and proudly dive it. All the parts you need...

    Vintage DIY.

    I will echo what others have said on the nozzle gasket. The white nylon one does not take too much torque and too much will def deform it. On the other hand the brown phenolic one requires more torque but at the same time you MUST get it in straight or it will crack in 2.....I have done both...

    Sea & Sea MX10

    Also, you need a strobe with any camera, if the MX-10 does not have one, you are still in need of a strobe, I had one and it was a great little camera in it's day but unless it was given to me, I would not use it

    Wanted Phoenix First Stage

    I just sold the last one. This is why I suggested you not worry about the rubber bits, they are rarely usable, esp the duckbill. If it's stuck to the cans, the easiest way to remove it is to pull off the easy stuff, then soak it over night in denatured alcohol, it will come off easily after...

    Not a problem. Don't hesitate to ask questions, the vintage community is fairly tight and more than happy to help new members.

    New to Vintage

    Don't be concerned with old rubber parts, they are very rarely good enough to dive...and frankly some of them just taste bad. As for the price of that one, it's on the upper end of what they sell for on ebay. With some luck and patience you can usually get one in the $100 range. Most don't have...

    Regulator Kicked Out of Mouth by New Diver

    I use to assist with OW classes, it happened at least once a class. It does not phase me now. :)

    New to Vintage

    Welcome to the club. Either an Aquamaster (aka DAAM) or a Royal Aquamaster (RAM) are perfect choices. Their Voit counterparts are just as good but harder to find and more expensive when you do. Like Mark said, all the parts you need to rebuild one are readily available as well as upgrades to...

    Help identifying old Scuba Pro 1st stage

    Yep, newer MK-2.....I would wonder about a LDS that does not know what it is, they are very common and have been around for many years. You can pair pretty much any second stage with it, a 109 would be perfect.It's not fancy but a rock solid reg.

    U.S. Divers "Twin 30's

    Just my opinion but not much. They are not vintage so they are not really interesting to a vintage diver- if they were older steel 38s with a vintage manifold that would be a different matter. . For a modern diver, they are each a nice size pony bottle or the best thing is a small set of single...

    Looking for Aqualung/US Divers Regulators identification

    The first stage is a Dacor Olympic 200 (1969-79). Unbalanced diaphragm that uses the same HP seat as the Dacor double hose regs. You can resurface it pretty easily. If you use it, be sure to set the IP at a low tank pressure (300ish) as IP rises as tank pressure falls, backwards from what you...

    New/old Nemrod Silver Snark III

    For the most part, parts are not available however you can always put a USD hose loop on it if the hoses need help. Performance wise, I have not dove one but considering they do not have any type of venturi assist, my guess is the breathing should be OK but not on par with a well tuned DA or...

    HP drop on inhalation

    Dang, that was your issue. :) That is NORMAL for a properly working J valve in the dive position. When in the dive position, the valve has a seat that closes under spring pressure and is opened by the differential pressure when you breath. There is always some pressure drop across that seat...
