[PSUBS-MAILIST] how to get acrylic

[brian]

Hope everybody is having a great time at the convention ! 
I need to get 8 acrylic viewports 1" thick by 6" in diameter.  How can I do that?  I have Jerry Stachiw's book and I could make the viewports myself if need be.  I also know of a company here in California, that Jerry used to deal with a lot, and they could do the annealing for me.  I just do not have access to the acrylic.
