Hand Press for Poseidon Cyklon Second Stage . . .

[Bigbella]

Scuba Clinic, of Thailand, has come up with a lightweight (210 gram), comparatively inexpensive (about US 70.00) alternative to Poseidon's 1.3 kilo, multi-hundred dollar "Assembly Tool," — both aimed at simply installing a 1.5 gram “locking ring” on a Cyklon second stage.

It is composed of three, nested POM (acetal) components -- one, to hold the regulator pieces in place, with a well for the stem of the inhalation diaphragm; a second ring, which fits upon the outer membrane housing, where the locking ring is placed; and a plunger, designed to install it in place.

It actually works quite well, though it initially took three tries, to get the ring seated properly, since it took a good deal of compression, to get things into place — beyond the initial "slight click" mentioned on the Scuba Clinic site. Think of it — for those familiar with the original Poseidon product — as just that initial, though not the final click of the “Assembly Tool” during the installation process.

Given the choice, I would rather not have to service a Cyklon, out in the field; but it is still quite nice to finally have something portable for a travel kit, should that it ever become necessary.

Oddly enough, Poseidon once offered something similar, in their European catalogues, about a decade or so ago . . .

Thanks for the review. I have been using a blunt pick from a dissecting kit to push the retaining ring into place, which works but takes time and significant effort. The hand press is now on my wish list.

I had a friend who could do all it by hand; but that technique always involved some blood-letting and colorful language on my part . . .

I was lucky enough to get a real press from Northeast Scuba Supply a few years ago for pretty cheap and when Scuba Tools sent me an email last week that they finally made one *I had requested it a few different times* I had to grab one. Don't think it will ever replace the beast, but nice to have a spare and a small one

I recently rebuilt a few Cyklons and have retaining ring installation by hand down to a 1 minute process, paying attention to avoid the pick slipping into one of the cover holes and puncturing the inhalation diaphragm.

This is how I would do it for a one or two reg personal situation but the Thai tool looks like a pretty handy tool for doing multiple Regs.
