Tool for Conshelf SE 2

[emoreira]

A dive friend of mine gave me a Conshelf SE2 reg set to verify because it was free flowing the main second.
The first test was to messure the IP. It was too high, reaching 14 BAR when the main second starts to free flow.
After dissasembly I could see that the only o-ring inside was too stiff and cracked. I guess this o-ring had more than 15 years.
Going to the point, the Conshelf service manual states that to assembly back the HP internals it's needed a special tool "High-pressure block guide (USD P/N III0-00)". It's possible to assembly the internals without that tool, but it's a nightmare.
So, impossible to buy that tool anywhere here, brain and hands to the CAD and I designed and 3D printed the tool.
Attached the STL files of the two parts.

Magnificent!

A slight difference with the original tool (as to what I could see in the service manual) is that my tool is threaded to the reg body, which allows a better fit.

I make those tools and have experimented with different materials. The issue I see with the printed ones is shaving of material by the circlip which gets into the reg. The clips WILL shave some softer steel so I can't imagine it would not shave plastic. It does not take much shaved material to cause issues.

Congrats on making the very useful tool.

It could be my old eyes, but your snap ring appears to be the wrong side up. The flat side should be up, not the rounded side.

Now that is good

I know that those seeger rings are made by stamping, The manual says that the "rounded side" should go facing down. But there was no such "rounded side" compared to a "sharp side". At least the difference was not notorious.
