[PSUBS-MAILIST] Gamma needs a diet

[hank pronk via Personal_Submersibles]

Jim,
I am sure after many dives over the summer, many plans will be made and changed.  I may want range extending battery pods or a diesel engine.  It is fun to day dream about this.  I am not allowed to drive when we work out of town because I am a danger from being distracted over this stuff. :-)

 Hank,
 Do you have room in your MBTs and
 reasonable access for small trawl 
 floats?  That wouldn't give you all of the
 additional needed buoyancy, but 
 it could make a contribution if they could be secured where
 they would not 
 interfere with anything including visibility.  http://trawlworks.com/floats.htm
 Maybe some iteration of lithium is in your
 future.

 Alan,
 That would work but I want to keep the sub clean on the 
   outside.  Gamma is very slippery the way it is. 
 I am confident I 
   can shed the weight.  I have been weighing all the
 bits and it looks 
   doable.  I am also looking at a winter project for
 Gamma.  I would 
   like to have the arm, and valve and a couple of
 positioning  thrusters on 
   a common chassis, like the DW's.  I could reduce
 the weight of the lead 
   drop weight because the entire assembly would be the drop
 weight.  That 
   also solves the weight problem from the batteries.  I
 would use the 
   original drop weight screw to drop the new 
   assembly.

 Hank,a
 simple solution would be to just have 
   a
 number of floats like Alec's Snoopy.He
 has them in a tube, but if the 
   floats had attachment holes
 you couldtether
 them & clip them on or 
   off.Alan

 Gamma or the pilot needs to go to Jenny Craig.  
   My new
 AGM batteries weigh 73 lbs each and Gamma has a 60 to 65 
   lb
 weight budget, per battery. That means Gamma needs to shed
 some lbs 
   before I can take a passenger.  I can switch
 to aluminum scuba tanks, 
   not sure the weight saving
 there.  I can make an aluminum rudder and a 
   few other
 parts 
   also.
