Definitely do one chamber at a time, there really would not be any significant time savings trying to do them all at once.

The BDMLR use unregulated scuba tanks (just an Aclamp leading to a suitably sized hose) to inflate whale pontoons (admittedly these are probably a higher overall volume than SIB chamber).

The flow is contolled using the tank valve and the "weak point" in the system is the hose connection to the valve (just push fit) so if pressure gets too high the hose simply pops off.

You just have to watch your fingers on any metal work in the system as it gets pretty cold.

great info fellas!

willk - thanks bro, I try to use my head, but sometimes impatience gets the better of me. In this case though, I think ill explore all avenues before I accidentally blow my sib apart. If you get the chance id love to see a pic of your setup.

jyasaki - the schrader valve concept makes sense.. What if I attached some sort of reducer before the valve attachment.. that could also reduce pressure no? Also, I'm not certain but like a bcd, I think that the valves on my boat have an overpressure release as well. I have been told that it does by people that are familiar with my boat... but also that it does not by equally reputable people. Something I'll have to find out for certain.

RIBase
You won't pop your boat using a SCUBA reg LP outlet, provided you keep a hand on the tube and check it (as you would if hand pumping it). I'd think your biggest risk (assuming no overpressure valves) is leaving her in the sun when pumped up.

I don't have a pic of my kit and I think it would only muddy the water, it's based around a very old AP Valves inflator and you won't have one. The pressure differences are minimal so just find a bit of hose that fits your RIB valve and insert/fix the SCUBA inflator to the other end - away you go.

Tip: Duct tape is your friend

the cost

hey guys am a newbie
keep in mind the cost (unless your a diver)
if your lucky enough to have an old scuba tank lying about keep in mind that the servicing costs are approx 60-80 every 2 years for the tank
if it aint serviced nobody will fill it

i have used this method to blow up RIBS with no problems we just used the air in the tanks before we went to refill them before a dive

Actually new regulation is hydro test every 5 years and a visual in the interim 2.5 year.

I've just paid 36 for a hydro and half that for a visual - so not as bad as you think. This was direct from a test centre rather than through a dive shop.

You're lucky. In the US, it's a 5 year hydro/1 year visual, and aluminum cylinders must be eddy current tested.

Gorgo,

Here you go - http://www.aqualogistics.co.uk

They are great, also good for regulator servicing - might be a bit of a trek for you but luckily I have an office just round the corner so am up there reasonably regularly.

Cheers

Mike
