Andre, I have 2 types of rings
in stock. -
Dome OD. -
Dome OD If you have some patience
with the acrylic I can make a full assy. http://www.nordicsub.nl/javasub-cor.html the steel band is laser
cutted and do not annoy the view Mmm every dome hatch
design should be a OD. of 610mm / Regards,Emile Van:

Namens André Eriksen Thank you! Makes abit more sense now. Looks like I will go with a dome
without flanges and O-ring on the edge. And a steel band to hold it down. Emile: Do you sell a full assembly? -Andrè 2012/6/15 Alan James <alanjames@xtra.co.nz> Hi Emile, It looks like you have a 28mm base to the dome & have eliminated
8mm with the 4mm angled cut away for the O ring & the additional recess for the retaining ring
around the perimeter. I thought the base contained most of the stress & you would want to
retain as much of it as possible? Are you still pressing domes? Regards Alan From: Emile <emile@airesearch.nl> 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: 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, Norway |
