Hi, All - regarding the acrylic viewports . . .
does anyone know how thick the viewports are/were on the dome type of subs like
Hikino, Deep Flyer, PC-8, Deep Rover, etc. (Makakai was constructed of
sectional pieces glued together - beyond my skills)
I'm interested in a 6ft. diameter hemisphere
to be used to 3 atm's (30 metres) max operating depth. One-atm
cockpit.
I originally considered using the half-dome for an
ambient-dry boat but, since 3 atm's is so shallow, I may be able to afford a
one-atm viewport. I have family that I don't want to subject to
barotrauma. They're all pre-teen and still growing.
Separate issue: Anyone with a knowledge of metal
may be able to suggest framework for this half-dome. I'm considering using
3 inch square tubing. Underkill? Overkill?
If it comes down to it, I'll just order a one inch
(at the apex) half-dome and use the boat ambiently.
