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

Subject: RE: [PSUBS-MAILIST] glueing
acrylic
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 Pierre Poulin

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!
