Re: [APML] Hypering Chambers

["Steve..." <swalters@worldnet.att.net>]

Once or twice on this list, I have read that people have made hypering
chambers from PVC. I think this is in AMOCAP as well.

Making the chamber itself is no problem, just cut and glue. But what is used
to get a decent vacuum seal?

I'm interested in making a PVC version just for transporting film in a
vacuum.
