Small issue with my Calypso IV today.

[Scuba Lawyer]

Since the 1990s I've used nothing but 1085 second stages for all but two of well over 300 dives and I'm having a terrible time figuring out how yours went adrift without you knowing it. Also what was left on your hose? I can't imagine what would make it come apart or how. Did part of the body actually break or what?

The Curious Frog ??

Just volcano orifice and a few threads.

I have a new seat that I got from Bryan. IP creep due to piston knife edge damage. Great breather but the IP issue needs fixing. What kind of trade do you have in mind?

Here is the piston I can mail to you,had to show off the extra box of regulators I found looking for the ammunition boxes of parts.

That's the way you take it apart after it comes off the hose and you're doing a complete teardown. I can't imagine how it would loosen up suddenly and drop the rest of the second stage. It must have loosened up over time, and as you say, just being held by a thread. I am amazed that it wasn't leaking like crazy for the whole duration of the dive.
The more I learn, the confuseder I get!

PS Once upon a time, I started taking apart a 1085 box from an Aquarius and what unscrewed easily was the joint you show. At the time I was told that was highly unusual and cautioned to protect that volcano valve so it wouldn't get nicked and rendered useless.

Off topic, I know.
More than you think, as my DMs say.
Family name, ex Navy etc.

Piston arrived today! Will let you know how the repair goes. Many thanks Bob.

Off topic, if you ever want spare parts for that rig , I have 2 ammunition boxes full of spare parts.
And for the J valve if you want it. Only divers of our age know what the J is about.
Postage would be a 'killer' though.

I just acquired a Calypso lV and would love to get parts to service it if you're willing? Also, does anyone know what the two bolts on the turret are (for)? I am guessing this is a simple first stage with a single hp and lp ports? (It would be neat if those bolts are lp ports.

Correct, LP

I am late to the board. I have a calypso IV and a sherwood buddy that i got after a friend passed away. I need to rebuild both of them as well as a seamless. If the box of parts are available i would be more than willing to pay the pistage.

I am getting some free flow in my pool, ut that is to be expected after sitting unused for a while.

I also got two alum tanks that i will get pressure tested and inspected. They are yellow (i know does not matter) aqulung tanks i am checking the dot no to verify they are not the ones with the alum issue. One had a safety reserve valve on it. They were presdurized when i got them but were last presdure tested in 1987.
