[PSUBS-MAILIST] Nuytco visit

Let me think. Post testing results: Internal pressure--as set. Internal temperature after 3 hours in a Canadian lake in February. Hmm. Best estimate, cold, cold, fricking COLD!!!.

Hey Hank,

Glad to hear you had an opportunity to drive to Vancouver and call on Dr. Phil.  That's quite a drive, but a bit warmer there.  Is Slocan Lake about six hours drive for you?

Do you have any plans for data logging during Gamma's tea bag test such as internal temp and presure?

Hi Hank,

It's   Alan not Alec. I believe Alec did have some sort of system. He   might

comment   when he wakes up. I think I've heard of a second line being used   to

open   an air tank valve to blow the tanks. You would need a valve with a   handle

on   the air line.

You   would't want to be on top of the sub when it hit the surface.

Another   thought is that if you used the electronic system you could have   an 

electronic   water sensor that additionally operated the system in case there   was 

a   substantial leak.

Alec,

Thank you, that is fantastic, exactly what I need.  It is   frightening spending so much time and money and letting it just sink away on a   line.  I will give you a call tomorrow after supper your   time.

Hank,

I'm jealous   of your visit to Nuytco, well done.

I have a few   random ideas of what you could do for your back up system;

If you had   solenoid valves on the air lines to your ballast tanks, then it    would

be very easy   to do. But that might cost you a few hundred & may be a   problem

adding in   retrospectively. A cheaper alternative may be buying 2 electric car door   openers

& fit   them so they can open the ballast valves slightly. If they aren't gutsy enough   you could buy a couple of cheap linear actuators.Then buy a cheap electronic   12V DC timer. Like this one.

& wire it up.   Make sure it's moisture proofed. Alternatively I don't see why you couldn't   use a mains power timer if you have one.

I take no   responsibility if Gamma is lost.

Regards Alan

While I wait for warmer weather to deep test my Gamma sub, I decided to   drive out to Vancouver and visit Dr Nuytten  and see all the wonderful   subs.  Dr Nuytten was kind enough to spend the better part of the morning   showing me DW's and some mature subs as well.  I had a great time   listening to fascinating stories and seeing how the big boys do things.    

Thank you Dr Nuytten.

I plan to haul my barge to Slocan lake where the water depth is 970 feet   in a week or so.  I will lower Gamma with a steel cable and retrieve it   1hr later.  I would like a back up, some way for a timer to tell Gamma it   is time to come home.  Any ideas would help, I have never tried putting a   backup together.

Hank
