Sherwood SR-1 "Problems" - request for first-hand experience

[BoltSnap]

Some pics of the used SR 2 second stage and the size of the first stage.
the second double adjustments, seems complicated but pretty simple, easy to set the cracking pressure to .8~ and seems stabile, very light.

metal orifice that floats is a good design idea, works well with ample lube

its about the same overall size as the MK 17 but slimmer, it has a swivel but I would love it if they offered a fixed end cap like the atomic Z, they didn’t seem to receptive to the idea

pretty hefty but yokes will do that.

internally the second stages are the same, I haven’t taken the SR2 first apart but the internals look to be the same. I’ll put A DIN on it after the trip and keep working it.

Are they borrowing their design from Atomic regulators?

No, or maybe only from the outside.
The technical design is very unique and different.
Have a look on the schematics.

That’s what first caught my eye, it’s a really good looking reg, at first sight. The SR1 came out in or around 2008 so Atomic was well established by then.
as axxel57 points out internally it’s innovative.

the second stage also showed its own innovation, perhaps @axxel57 cap post that schematic too?

Sure......

Interesting that the “C” clip is not on this drawing but my new SR 2 has it. I recall someone posting about a broken clip and having a hose issue but after getting inside the seconds (one sr1 doesn’t have a clip and it’s fine) it appears to only serve as a limiter for the adjuster (#17) as it’s completely inside part 36. I really like the floating orifice and this external adjustment.

When are you diving it?
