Which BOV (OC/CC DSV)...

Yes.

FWIW The reason I am asking for more information is that I have heard very positive reviews of the Nemotech elsewhere. My inclination is more towards the Divematics, but I wanted to get as much feedback as possible.

I am discounting the KISS as I am far from a natural fettler, I don't want to have to play around with anything not designed to be on an Inspo. Adaptors fill me with fear....

I've got a Nemotech and have no problems what so ever with it. I got it about a year ago and had good communications with Filip, delivery was under a month.

As for fettling - it was no problem. It came with the Inspiration adaptors (included in price) iw was simply a caose of taking the old hose conncetors off, popping a plug in both ends of the hose and tightening up the new hose connectors. You have a choice of which was you want the OC intake to go. Decide which way round you want it then tighten up four screws.

Thanks Skippy - my kind of price!

Could you post the plans/drawings for this? Just curious...

Ha ha, how about asking him to provide a full set of engineering drawings while you at it?

Actually, tell you what, if someone wants to send me some engineering drawings I will look at seeing how cheap I can get the parts made up locally (less 2nd stages). I dont mind knocking out a load providing I can cover all costs but I dont have time to draw it up.

That would be the exception rather than the rule. Many people were/are well pi55ed off and some, myself included, were glad just to get their money back! Maybe he has his act together now - but a year ago it was close to turning very ugly.

I think I just did!

I think your idea of knocking up a load would be great! I'd take one if the costs are good - Part #1 for my BOB!

Folks,

Just as a note of info, if you contact Tracy Robinette at Divematics USA, he will make the BOV to fit your unit. He will put the threads on it that you need to fit your hose connectors. (NO adaptors)

You pick the second stage you want on it. If you have a "favorite" you can send it to him for installation. Otherwise, just specify what you want.

He can be contacted easily, and speaks American English as a native tongue. (I mean this as no slight to our readers who are not native English speakers. I only mention it as a plus, since most of our readers do speak English well, sometimes among their many languages!

) He is friendly, reliable for quick production, and offers good product service if needed.

The best thing is that, with the strength of the Euro against the dollar, the exchange rate essentially cuts his price in half, and even tends to make up for the VAT (if you have to pay it)!

Give him a shout at: www.divenet.com/divematics

Cheers!

Well, I collected my Divematics from the US last week....

It was the first thing out of my suitcase when I arrived home this morning, and was on my unit in about 5 minutes! Looking forward to trying it out this week.

Showing the MantaBite I fitted, which I am getting along with nicely now.

I still have some minor tweaks on the hose routing and connection to on/off board, but I'll develop this from some ideas I already have...

***caveseeker7*** · 18th September 2005, 17:18

Nice going Simon, looks good.

nmanfield · 19th September 2005, 03:43

Nice one Simon,

We'll have to go for a play when I'm back in the UK in 5 weeks time

Hey Skipbreather!

Im just about to try a similar BOV stunt as you did and assume you went with the no-oring approach as you are talking about 0.001" tolerance. I generally always try to do things with as few orings as possible. Once you got the tolerance where you wanted it, how easy or hard is the spool to turn?

All the best,

Andy

Folks, you’re overlooking another obvious source beyond the four mentioned. Sadly, I believe it may actually be only 3 since rumors have it that Bob Howell has pretty much been beaten about the head and shoulders by government bureaucrats into ceasing commercial production. Hopefully I’m wrong about that.

Fortunately, in the USA at least, there aren’t any SCUBA police- yet. It’s still legal to dive any bit of kit you choose to build yourself. I chose to design and build my own OC/ CC DSV, and I’m very pleased with the result. Granted, not everyone has a lathe in their basement, but I find it difficult to believe that out of all the members of this board, only the four gentlemen listed- all making great kit- have those abilities. Guys, where’s your creativity?

What you see in the pictures was built using a 63 year old South Bend 9 inch lathe, an ancient drill press, and a Dremel tool (the brand logo was stuck on in jest). That’s it. The diaphragm/ exhaust valve & cover were salvaged from a corroded out Zeagle Octo +. The OC guts were stolen out of a Sherwood square octopus. The one way valves came from Divematics. After that comes thought, patience, and close attention to detail- and I do mean CLOSE. Biggest thing I learned in the process was that the tolerance for fit of the spool to body was less than 0.001 inch if I expected to get a good negative pressure check.

One other thing going on in the pictures that may not be readily apparent is the quick disconnect attaching the OC supply hose to the DSV. I’ve not seen anything like it for sale anywhere. It is ultra simple to build and makes disassembly and cleaning of Rebreather hose/ DSV assembly much easier. It is just a 1 ¼” long piece made from ½” diameter 360 brass stock rod. One end is machined to duplicate the end of the hose that mates to the second stage. The other end is machined to duplicate the Zeagle/ Apex quick disconnect that is used on the Zeagle Octo +. It is secured to the DSV with a nut from a discarded second stage hose. A standard Octo + supply hose feeds the DSV and just pops off when it’s time to disassemble & clean.

As I said, I realize not everyone has the tools/ ability to build these sorts of things, but hopefully I’ve gotten the creative wheels turning in those of you who do- and in those who want to learn. Let the Derlin & brass chips fly!

Oh, and yes, that IS a Mark Munroe unit replacing my stock secondary!

Can your NC machinist read Solidworks files? If so, I might have something for you very soon.
