acrylic
Thank you for the useful information,
I was studying the possibility of constucting a
dome from ring of 50 mm acrylic plate and then machine it (This was
discussed before).
Just add 25 % wall thickness for glue
uncertainty.
Why not thust glue? All modern airliners are glued
together.
I am also working on a tool for blowing a dome, wich has
a better material efficiency.
Grs, Emile

I worked for the university of Colorado for a few years and we used
lots of Acrylic for building test models of buildings and Dams and just
about any thing that needed to be built. We used a glue called PS 30
and it was very strong. It's a two part glue and if the two components
where not in just the right amount it would craze. But I never saw any
of the joints separate. However,,,,I would never ever consider using
anything but a full piece for a view port. DJB

Hi
emile,
My friend work at the university here and he glue acrylic
all the time. I
asked him and here is the answer...
You need: a
tank about 0.5" deep and Dichloromethane (french word sorry).
How
to do: let's say you have a viewport of 8" diameter. you need about 1/8"
of Dichloromethane on the bottom of the tank, then you drop the
viewport
into the tank so all the surface you want to glue is dipping
in the dich...
wait for about 15 secondes, pull up the viewport about
press it to the other
surface.
Results: My friend says that you
may have some small bubbles trapped between
the 2 parts. As for
strenght, he says that it is as strong as a full plate
of acrylic. he
does boxes shape and when they "destroye" them, the acrylic
almost
always break right next to the join. Not the join itself.
Hope it
helps!
