[PSUBS-MAILIST] Gamma needs a diet

[via Personal_Submersibles]

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.
