[PSUBS-MAILIST] Gamma bow dome

[hank pronk via Personal_Submersibles]

Thanks' guys,
Pete, this is Gamma with a face lift :-)
Alan, I have looked at some subs with straps holding the dome, even at Nuytco.  Dr Phil's deep diving sub has straps, darn can't remember the name of it.  I am using straps because I don't trust my engineering to produce the retaining ring for a 180 degree dome.  There is not much angle for a ring to grab on a 180 degree dome.  As for leaking, I am using an EPDM 1mm gasket under the dome and the aluminum ring has an o ring in it against the reinforcing ring. The straps pull the dome down as tight as I want, so I feel good about it not leaking at the surface. I also have lifting eyes on the straps to help remove the assembly, it weighs 185 lbs.  I am still sorting out the rubber to put under the straps.  I am using pond liner rubber  now for mocking up.

   dome is on and I can not
  believe how spectacular it is.  I
   can sit
  upright in the front of the sub and operate it from
   the front.  It is weird to look out because
  it is as if
   there is nothing there.  It is
  hard to explain.  I will
   build new 
  ballast tanks in the next week or so and I am
   back in the water.  I am mounting Nemo style
  split tanks
   that vent from Gamma's
  original vent valve.
