Not bad. But it is also not done
to machine a o-ring groove in the dome. Nemo’s first dome cracked when
the water o-ring froze! Attached my solution. Green
is o-ring Emile Van:

[mailto:owner-personal_submersibles@psubs.org] Namens André Eriksen From what you said I made this sketch (attached). Is this a good
way to fasten the dome? -Andrè 2012/6/15 Emile <emile@airesearch.nl> Hi Andre, It is not done to drill / tap any holes in a
acrylic dome. Stressraiser! For shallow divers you can glue . Under high pressures the dome contracts more than
the ring I use a o-ring on the edge and stainless steel
bands hold down the dome. Flange also possible for shallow divers. In the
handbook of acrylics are some examples. Emile Van: owner-personal_submersibles@psubs.org

Namens André Eriksen Hi, I`m new to this
forum, and are planning to build a 3 person sub. I can`t seem to
find any plans or pictures on how to fit the acrylic dome for the
hatch. Is it screwed down on flanges with an o-ring underneath, or liquid
gasket/glue? I`ve seen some domes without flanges, how do they attach them? thank you. -Andrè Eriksen,
