small improvement on a Dolphin DSV

venturi · 16th August 2007, 09:33

Hi all,

because of a dry long period and a new barrel for the dolphin dsv, I decided a small improvement in order to get a smoother functionment.
First, by polishing the inner side of the dsv with a Dremel and its polishing paste : even with a good cleaning, some wearing out appeared at light, where the blue o-ring moves. Now its like ice...
Second, I changed the original black plastic opening lever by a longer nut (ok, from an Ikea bed, according to the notice) : better with gloves.
third, from a small plastic tube, I made a removable extension just in case the DSV becomes stiff.
I don't know if this have been made before (and remind that the only valuable grease for it is really the Molykote 111. Don't ask me how I know that

).
attached, a picture of the whole thing.

Good to see people still doing stuff with these workhorses.

Is the DSV from a Dolphin or an Atlantis? Or is the picture you posted before you completed assembly of the DSV?

I ask because it looks like the threaded section for the hoses is missing.

Good work nevertheless.

yes, it's from an Atlantis DSV.
the new long nut is not SS, but since it's a M6 thread, I suppose I can find something equal in shipchandlers.
