Hi
Alan,
Nemo 100 makes the
domes also with the hot pressing method.
Blowing is the
simplest way and make the tooling is the least effort. Limit is 200 metres
in my opinion.
Pressing is far
better for roundness , material efficiency and
thickness.
For the 24? / 610
mm OD. Dome we start with 35 mm plate. After forming it is still 35 mm on
the edge and 25 in the apex!. Good for some 500 M
;-)

Thanks Emile, well done, enjoyed
looking at the photos.
I had a quote for a dome from
Jürgen Herrmann from Nemo. I assumed it was a
cast
dome as he said could provide
certification for it at an extra price.
I had a blown dome made for me
locally, wich turned out good. I think there was a bit of luck
involved.
Due to cloth being glued to the
acrylic disc's bottom surface, the bottom face had less friction &
dragged
into the dome more than the top
surface. The outer edge of the flange sloped inward as evidence of
this.
This was a desirable effect as
that edge has further to travel around the curve of the clamping
plate.
Would love to have a go at this
some time, as I was involved with a process where copper was
drawn
over a mold in a similar manner
& have some ideas I would like to
try.

Alan,
We make the domes
ourself with our friend Reinhard from Nemo. We developed tooling and
Reinhard buildt a oven with intergrated hydraulic
press.
I not say it is
easy. 1 of the many parameters wrong and you destroy a day work and the
material (Euro 800,- for the small dome and 2300,- for the big dome)
Say 1 to 4 goes
wrong.
I somebody go
?try this at home? I would advice to start with a 1:4 scale
setup.
There are some
pic?s of the domes on :

Regards,
Emile

Carsten,
Wondering where you got the dome
made?
Was it a reasonable price?
Great to know we have a submarine
certifier on our site.

The first picture shows a quick and cheap way to
create an own submarine pen for small subs.
The second picture
shows the view from a dome with 950 mm Diameter (37 inch) after rebuild
the bow from the original 600 mm (24
inch) dome.
Both pictures
taken last weekend at the Kreidesee in Hemmoor, Germany
