Grrr!
Not so much a rant on the glass, but the glass guy that ordered it. Apparently, 3/16 somehow translates to "4mm", according to his math...
I get home with the new glass, and take a closer look at the receipt, and see the 4mm written on it.
I'm pretty annoyed, since it takes 1-2 weeks to order a sheet of tempered glass in custom sizes, but I'm sure it's not a good idea to run 4mm thick glass. One good air ball, and I'll be picking glass cubes out for weeks!
Curious though, has anybody used such a thin sheet on a pinball without risking a nasty clean-up?
