I've got two sheets of 3/16" by 29" by 47 1/4" glass sitting here in my shop, just waiting for me to trip and break. Somebody in the Seattle area come save 'em from a horrible fate. They'd be perfect for an 8 tube flourescent exposure unit.
I'll toss in timer from an old process camera (only 60 seconds) to the first people who wants it. PM me and I'll check when I get home early this AM.
