[PSUBS-MAILIST] roundness

Fri Jul 24 15:37:11 EDT 2015

Brian,
The pod needs a bit of ballast, enough to keep it upright at the surface, but no stability.  The pod will have an inflatable skirt ( truck inner tube) around the hatch, that I will inflate before opening the hatch.  The tube will be hidden under the fairing between the sub hull and escape sphere. The sphere will have O2 and micro scrubber as well as surface snorkel.  I will store My emersion suit in the pod.

 Hank,  You have a plan for
 getting out of the pod ?

 Brian,
 I think a good fabricator will provide what you ask
 for.  Edmonton Exchanger is a pretty Kik Ass outfit.
 Building an escape pod may seem excessive I suppose, but I
 am just not feeling comfortable at depths that I can not
 swim out of.  I can build the pod for under 5K, that
 seems like pretty cheap insurance.  Remember I am not a
 diver and I will spend most of my time at 400feet.  
 I did consider building a second Gamma, just make a copy. It
 is much cheaper to build a pod and pretty quick also. 
 I am not sure I could build a replica Gamma by spring.

  Basically what it boils down to is
  how humanly possible it is to get it as near as perfect as
  you can.  If you first instruct the fabricators to get
  it as close as possible, then you need to go from
  there.  You can always massage it into a perfect sphere
  by using the proper amount of leverage. 

    It seems to me, though, if you're going to have an
  escape pod you might as well just build another sub for
 all
  the trouble it will be worth.

   Hi All,
   Can someone tell me the allowable out of roundness
   percentage is for a sphere hull.
