Alan,
I was thinking about welding a ring to the remaining section of steel ballast tank, then place the dome with a small flange on the ring.  Then another ring to clamp the dome's flange.  I don't like the idea of drilling the flange.  I got a price from Vancouver, 664 dollars for the 3/8 thick dome.  Got another price for 1/2 in dome from Nova Scotia 1,000 dollars US plus shipping.

 So are you
 going to mount the dome with it's flange
 on?ie. weld
 on a circle of bolts & have a soft gasket that the
 domesits on
 & then another gasket & a  retaining
 ring?The reason
 I ask is that the retaining ring could also be used in
 the dome
 forming process to clamp the dome down & save
 youa
 bit of money. Alan

  Alan,
  As per
 
 ABS rules, the sub can surface on one ballast tank.  Also
 I
  could drop the lead weight that is in the
 front.  I found a
  company in Calgary (3hr
 away)  that will blow me a dome 3/8
  thick
 and 3/16 at the apex. I am trying to find a heavier
  one still, but it's a start.

   Hi all,
   I am looking
 for
  a 36
   in ish dia
 acrylic dome.  The dome
  will not be a
 pressure
   dome.  I intend to
  remove the front ballast tank from Gamma
  
  and replace it with an
 acrylic dome.  The dome will act
  as
   the new ballast tank.  I discovered
  that sitting in the
   front
 of the sub, the
  visibility is quite
 acceptable if it
   were
 
 not for the steel ballast tank.  
   Any
   leads would be appreciated.
 
 
  Hank
