The last time I went to an arcade I saw few, if any, cp's that had bolts showing aside from one in each corner of the plexi. There were only about 8 or 10 games or so as it was just a little movie theater arcade, but...
I wasn't planning on using plexi, though, for better or worse. I'm planning to laminate my control panel with a brushed aluminum laminate and not planning to use artwork on the panel. I know, blasphemy, yada yada yada.... I'll just have to rely on the buttons and sticks themselves as a counterweight to the otherwise flat plain issue.
Question, though: If I need to remove the stick can't I just pull the nuts off and remove them from the bottom...carriage bolts remaining in place? I've never mounted a joystick or buttons yet.
