Apologies if this is answered elsewhere, I did a quick search and didn't see it.
Anyway, I'm about ready to think about moving my CP from a shoebox to a real box

and I have some questions about mounting the joystick.
Ok, I assume you're supposed to attach the plate of the joystick to the bottom of the CP top? After a quick measurement, it seems that the joystick is only about 2.5 centimetres from the plate to the bottom of the bat handle.
How thick is it a good idea to make the CP top? and how long "should" the joystick be? I'd rather not get into routing out the bottom of the panel or anything like that, seems a little beyond me at the moment, are there any other solutions? or will it play just fine as it is? and one last thing, how big should the hole be for the joystick generally?
A few questions, I know, but this is one area where I'm kinda stuck.
Thanks.
