My question is, can I fabricate a stainless ring and
connect it to what I have now ? I could remove some of that
material ( the ring part ) which is 3/4" thick so as to reduce the
weight. I'm afraid if I don't make that ring part thinner the hatch will
be too dam heavy.
Hello,
I also think weight saving op top of your sub is an
important issue. You have only weight stabilisation.
Personally I think alu is a good idea for weight, cost
and machining reason. Corrosion prevention by painting anodising or even
not nessecary.
It is a flat hatch so it has to be thick an/or has
frames

Is it possibel the Needlefish have stability problems
due to the large/heavy tower structure??
