Orange County Industrial Plastics in Anaheim is where I get most of my plastic
material.
Norton Sales is mostly doing movie rentals these days from what I hear. I
haven't talked with Carlos for over a year.
Try to get some remnants from a company that installs bullet resistant glass at
banks. They should have some small pieces.

Thank you Mike. I’ll stand by until then.
For a vacuum chamber, I don’t think I should try to laminate thinner pieces
together. High vacuum has a tendency to pull stuff apart.
The chamber will be approximately 42” long and 5.5” ID square. The clear
plastic is for the ends. For the thickness of the clear plastic I would like
the best optical quality possible. I’ll be viewing through the ends of the
chamber using a video camera. (I’m not going to be sticking my nose up
against the end of a 3 ½’ long chamber with high vac inside.) The other
walls of the chamber are ¼” thick aluminum.
I found 1 ¼” thick bullet resistant (sometimes referred to as just BR
plastic) at the local recycle yard, but I would have to purchase an old bank
door that weighs about 500 lbs.
I appreciate all the help with this. I’m working on fixing up the mechanical
pump now and will post some photos when I have some substantial progress.
First, I want to assure that the pump is working well.

[roc-chat] Thick clear polycarb for vacuum chamber

I’m looking for two sheets of ¾” to 1” thick clear plastic for the ends of
a vacuum chamber. I need them to be at least 8” square.
Any suggestions on suppliers? New material from places like McMaster or
Industrial Plastics Supply are very expensive and my usual recycle place
doesn’t have anything like this currently.
Thank you,
Richard Dierking
