Alec,
Sorry, I thought it was Brian asking.

 Brian,
 The sphere pod
 connects to the stern.  The rear ballast tank goes and is
 replaced with two more saddle tanks.  The exsisting motor
 drive will be replaced with oil compensated jettisoning
 thrusters.

                             Hank, I'm not
 following. Where does the sphere go and how to you get from
 cabin to sphere? I ask because I would have imagined at the
 stern, but you have a big prop back there.

 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.
