Hey, it's no
problem, - a methyl methacrylate monomer is industrially produced by reacting
hydrogen cyanide with acetone to yield acetone cyanhydrin. This acetone
cyanhydrin is mixed with concentrated sulfuric acid and heated to form a crude
methacrylamide sulfate which is reacted with methanol and water, yielding methyl
methacrylate and ammonium bisulfate.
Maybe leave
it to du Pont & Co.

biggest problem with DIY is that you cant really
trust the qualtiy of the cast... i know that i wouldnt trust my handywork in a
1atm sub at any depth. but that be said i have little to know pratical
practice with acrylics..

Does
anybody know what would be involved with actually casting acrylic on your
own? What is the proceedure ? and can the chemicals be
purchased? I guess I should refer to my acrylic handbook
!

Brent, I think that would be for a blown dome. For
a cast dome I forget the number but it was WAY more than that I'm
afraid.

Subject: [PSUBS-MAILIST] cast dome cost
Hi people,
Can anyone give me an indication of what a cast
acrylic dome costs.
Something round the size of a K250 dome, 24" x
1" thick.
Or any dome that you know the dimentions
of.
Thanks
Alan
