My viewports aren't near as pretty as those, but here's another question.
Do they need to be that close ( .5 mm ) ? I've seen some that weren't anywhere
near that close, and I assumed you need a little space around the plexi for
sealer and possibly flex of the frame when diving deep. I am planning on
ordering the plexi 1/8 inch small, so there won't be any direct contact between
the plexi and steel. Am I screwing up? Frank D. |
