From what you said I made this sketch (attached). Is this a good way to fasten the dome?

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.

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.
