I’ve read a lot of good ideas here.
It’s great to have this kind of forum. Back when I built my sub (early
90s) all I had was Busby’s book and the PVHO. Looking back, I would say
that the ideas of mine that turned to be, shall we say, “less than useful”,
were all of the ones that were “over thought”! But it is
still fun to brainstorm and be creative. As far as the PVHO goes though, I can’t
stress enough that it should be the basis for every design. Just in the area of
acrylic fabrication, it still amazes me just how thorough their investigation
into the properties of acrylic was. As an acrylic fabricator, I don’t
think of that work so much as “rules” but as “discoveries”
about the material and how to shape and contain it in ways that allow it to withstand
tremendous loads. It’s like the alphabet- there is no limit to the great
literary works that can be created using the alphabet and there never will be.
This is also true of basic pressure vessel design. The fun is in the
combination. I’m currently building a new sub. I
think I’ll visit the discussion more often in search of new ideas. Thanks, Greg C From: owner- All good advice Greg. It's real good to
have guys with real experience to give advice and critique our sometimes
hair-brained ideas. I can see where a towed buoy could be a
pain although I did like the idea where your surface crew could tell how deep
you were by counting the floating pipes. I'm hoping David's comm system works
out so we are able to talk to the surface without dragging an antenna
along. That should be a VERY good thing. Frank D. |
