[PSUBS-MAILIST] roundness

[hank pronk via Personal_Submersibles]

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.
