[PSUBS-MAILIST] Gamma

[hank pronk via Personal_Submersibles]

 Hi Pete,At 24 V my motor is 2 hp and draws 50 amps.  I still use the mechanical valves because the MBT's  are long, so when the sub is on an angle they won't vent completely.  With the electric valves at the opposite end of the tanks I can vent them easily.Hank

  How many HP is that aft motor?  Are you still using mechanical 

valves on the fore MTB's and why? Are you plumbed fore-and-

aft?
Pete

  Pete,I put the original magnetic coupled drive back in the sub.  The rudder is not welded, it is how I steer.  I have added 4 solenoid vent valves but am only using two in the aft tanks.  Hank

 Hank, From the latest pictures I've seen of gamma it looks like 

you're using the single inboard thruster aft. I've also noticed that 

you've welded the rudder. If that's true how do you steer

Also are you using your new electric MTB vent valves? If so 

pictures would be appreciated.

Pete

 You could push the bottles closed before you surface. Maybe poke a pin hole for OP. What are you sampling?

 What about empty dish soap containers. Fill them at the surface with water and at sample depth squeeze them to partially empty and create a vacuum to suck up your sample.

 Okay fellow submarine nerds, I need an idea.  I need to find containers for taking samples off the bottom that when they are squeezed they open a lid.  Ideally I would grab each container from a rack and when I grab it the lid opens from the force of grabbing it.Hank_______________________________________________
