[PSUBS-MAILIST] scuba reg problem

[Alan James via Personal_Submersibles]

Hank,
you have all the bases covered there. The first stage will adjust the pressure to 130 psi
above ambient as the pressure increases in the hull when you flood it.
Still you don't need a leaky regulator as it will be of no advantage to you in this situation.
Better to maybe have the air on to it when diving in case you left the hatch open or a fire
or something. Look forward to seeing it in person.
Alan

Alan,
thanks' for the post, you are a machine!   
Gamma has two hp tanks inside for ballast control.  There is a manifold with check valves that takes the two air supplies and has a fitting that accepts a scuba regulator for emergency breathing inside the sub.  
Also I just watched a you tube video on escaping from a sub to 600 ft.  I also just bought an apparatus shown in that video on ebay,lol.

Hank,
if we are talking about a first stage regulator that will be on the bottle outside
the hull, you will have to turn it on before the dive.

It is a Sherwood regulator, so  I can assume it is normal .  I will only turn it on in the event of a smoke filled sub.
Thanks

The exception to this would be if the reg is a Sherwood. Sherwood first stages use a dry air bleed system which constantly vents a miniscule amount of gas, instead of allowing seawater into the balance chamber. While this works, it makes it difficult to distinguish the bleed from a problematic leak.

>>I bought a scuba regulator set for emergency breathing.  When I pressurize the system, the first stage regulator is venting out a small vent on the side of the regulator.  The vent hole has no threads, so I assume! it is a
vent.  The amount of air is very slight, is this thing screwed.  It works fine otherwise
