[PSUBS-MAILIST] Gamma bow dome

Thu Apr 9 21:17:32 EDT 2015

Alan,
Yes that is Nuytco's sub that I mentioned or at least the same type.   That is where I took the idea on how to tension the straps, :-)
I thought the straps might be irritating to look past, but they are no bother.

 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.

 believe how spectacular it is.  I
    can
 sit

 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.
