Hole Dimentions

[waters_jim]

For a 3 inch Harp Trackball what size hole should be cut. Also for the Joystick and Harp buttons?

Thanks,

Do you have a mounting plate?  I'm not sure how you would do it without one unless you plan on removing A LOT of material underneath.  If you have the mounting plate, this is all you need: http://forum.arcadecontrols.com/index.php/topic,119081.0.html

I am pretty sure the hole you want is 3" exactly - that's the outside diameter of the lip around the trackball.

Buttons are typically 1-1/8" for buttons and joysticks although I've been cutting my joystick holes 1" lately for... reasons?  I don't know.

Whatever you do, test everything on scrap before committing to the real thing.
