Strangely enough, I haven't been able to find this information anywhere online yet.
About two years ago I ordered a set of standard arcade buttons and two 4-way joysticks from eBay. When they arrived they lacked any paperwork, so I don't really know any measurements on them. As best I can tell, they're basically sold as direct replacements for already existing control panels.
Tomorrow I'll most likely be building my control panel, so tonight I'm hoping to draw out the plans.
What size holes do I need to drill for the arcade buttons and joysticks? The wood I have is roughly 3/4" thick. I'm not sure if these controls come in varying sizes, but from what I've seen they seem fairly standard.
