Hello:

Okay, I appologize for that my sarcastic remarks earlier. However,
after a long run I am much more relaxed.

For the "I wanat to go diving" folks who were asking for air supply
advice.

But for real try this........................

Oregon State University DIve Ops guy, Jim Washburn used an old USN hand
operated diver air supply pump to guide a new lilght weight v3resion
for shallow water applications.

I am not talking about the big two person pump designed put a Mark V
down, rather somthing much smaller.

The shallow water pump weighs about 25 pounds and is pumped by one
person. The diver uses a "special" low preasure demand stage for the
regulator.

The pump is prettey cool. Stone age technology. Maybe four moving
parts. And the beauty is that only one person is needed topside to work
the pump.

Where do you get one??

Jim was cosidering manufaturing and sell the pumps. But because of
libility issues decided to shelve the idea.

However.......... if you are interested call Oregon State University
and ask for Jim Washburn, College of Oceaneering. I have a set of plans
but Jim is there to do just that. Help the tax payers benfit from tax
paid research projects.

Two bighest problems with this set up:
1) limited to about 20' depth
2) need a person topside to operate the manual hand pump.

The advatges:
1) No fuel,oil,noise
2) Stone age relibility, simplicity, light, CHEEP

Helpful Bob.
