DeepDiver,

But those are diameters. So you have to divide by two to get the actual
"overhang". In this case, 3/32", way too tight a tolerance for using hole
saws. Also realize that if the holes are loose, your buttons may wiggle
around when the arcade action gets hot.

I didn't think about that.

That's too fast. You're going to want something around 100 rpm.

Is this a deal breaker for drilling? It really only goes down to 585rpm.
Should I look into punching instead or try to find someone who can do it for
me?

Thanks and have a great day,

Alan
