Who has broken a sheet of pinball glass? (The Judge, I'm looking in your direction)
I haven't yet, but I'm sure it's a matter of time. I think about it every time I pull a sheet off a pin or I"m putting one back on. Sometimes I can feel the tension I'm putting on it, if I don't catch both channels just right and have that "Oh shit!" moment until I get it straightened out.
I'm sure the guys that have been in the hobby a long time have broken multiple sheets.
