[PSUBS-MAILIST] information on viewports

[Cliff Redus via Personal_Submersibles]

 Jeff, I concur with Jon, Sean, and Alec for all the reasons they note.  Stick with PVHO design for viewports.  Calculations for the viewports are straightforward to understand.  It is kind of nice to sit in a Psub at 300 ft and look out a viewport that has been designed according to PVHO rules and not have to worry about the mechanical integrity of the viewport.  The typical factor of safety of a PVHO viewport is on the order of 4-5.
Don't know where you live but a good starting point for designing a 1-atm Psub is to attend a PSub or IS diving event and look at boats and ask lots of questions.  Hopefully, we will have at least one PSub and/or IS event this year.

Hi:
 
  
 
I am new to this organization and am currently in the design phase of a two person submersible. I am looking for information on obtaining acrylic viewports or learning (if possible) how to fabricate my own.
 
  
 
Thanks,
 
  
 
Jeff
