Re: [PSUBS-MAILIST] Sub as panoramic film platform




Hi Brian,

I figured it was something like that.  Nothing wrong with a 27:1 safety ratio anyway.  :)

Other than the labor of cutting and grinding the thru-hulls, I can't think of any reason you couldn't reuse the flanges if you wanted to.

Jon,
              Back when I started I was designing for a 3/8" thick pressure hull and more depth, now I'm leaning toward a 1/4" pressure hull.  I made the viewport flanges a long time ago.   BTW,  what would be the feasibility if someday I decided to upgrade to a thicker pressure hull and wanted to cut out those viewport flanges and reweld them into a different pressure hull?  Aside from a lot of grinding would there be any issues that would prevent one from doing that that you know of?  The viewing area is actually only 4.5"
