Re: [PSUBS-MAILIST] Welder with Vision

Rob,

What you discribe makes me think of a Perry Cubmarine (If you don't know
what that looks like have a Google image search for "PERRY CUBMARINE".) A
design like that gives you the opportunity to have 2 people sitting upright
in a small sub. I fear that it is complicated to design (stresses!)  and
build. Is this the concept you have in mind?

Geatings,
Thijs Struijs

something to get my questions answered.  I am in the process of moving from
one home to another, once settled in, I plan on building a cardboard mock up
to nail down the measurements.  The pressure hull is nothing more than a
pipe with end caps (30 or 45 Degree Cones), the pilot and passenger are in
the sitting position, their upper bodies and head are in the conning tower.

the forward end cap on the conning tower ( that is cut in half or shaped to
match the surface of the pressure hull ) can I mate a pipe flange to that -
given all the angles ?  Am I asking for a fabrication nightmare ?
