More silly questions...

[Digger]

OK, now the one-way vlaves are getting sorted out, I need a couple of bits of info.

How many do I need in a dual couterlung arrangement, and where? Where are they on your units, why have one in certain places, and can it hurt to have too many (can't see WOB going up much with a couple more than I need really) and also what happens if there are too few?

Can I get away with one either side of the mouthpiece? If so, great, if not, why not?

Thanks again guys. More questions I don't have the answers to. Isn't most of this in a book somewhere???

Digs.

And has anyone got a good source? I need some with a housing about 22mm across.

jack please just stop.
You would me missed down the pub. speaking of which are you coming down this thurs

[Digger]

I will, and I'l lbe celebrating as Jen's going to fly through her interview. Getting there early probably - you guys going to run there? Could be a good indicator of how fit you really are!!!

What about these guys? http://www.cpr-pro.com/replacement.html They're Laerdal, so should be easy enough to get, and 22mm quel surprise! Any reasons why not? And at less than $2 they're not going to blow the budget. Should get through customs cheap as medical equipment, but I reckon there's going to be a UK supplier.

Jack, as a mate please stop this madness, you really dont know what your doing, you forget that i've seen your very primitive engineering skills and knowledge, apes can use tools better than you. Please don't kill yourself due to your blatent ignorance of engineering and engineers, just cos you've got a management degree. Remember its engineers that keep managers in a job

Speaking of the pub, come in your dirty clothes as i'll be doing my usual trick of trying to get everyone to go to Ocean, you know it makes sense, and Kev we will drag you there again, kicking and screaming if we have to.

Hi Digger,

I'd be a bit careful, it's possible the 22mm is the fat bit in the middle. The outlets are probably a lot smaller. It also seems quite narrow, OK for an O2 RB but I'd maybe think about going bigger before you spend anymore on mods.

On most RBs there are one way valves either side of the DSV and that's it. The only real reason to have them anywhere else is where they are doing a specific function like on the RB80.

Try www.vintagescubasupplies.com for decent one way valves. Many others don't stand up too well to diving use.

Cheers,

Stuart

And bring folding money, Tim, or I'll break your legs.

Yes - Mastering Rebreathers by Jeff Bozanic - it would save bandwith if you read this.

I will be there also trying to talk sense into Digger. I've had/still have the benefit of regular contact with some of the UK's most experienced rebreather using cave divers. You cannot build and learn to dive a CCR from a correspondence course on the internet alone.

I thought that was how DIR divers learned to dive?

Well you can - but theres a very high probability youll die.
