Yes, I am rather pleased, I was expecting a big number.  Varsteel only needs 2 days lead time, things are slow.

 I'm surprised that EE gave you a feasible
 quote, but I guess with oil prices down they're not
 making too many 12" thick 144" hemispheres these
 days.

 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 p!
  ossible
 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.
