I'm a little confused..Has anyone installed an Xarcade trackball before? The only instructions I found state to router a 5 7/8 x 5 7/8 square down to 1/4 inch and cut a 2 7/8 hole. I'm using 3/4 inch Mdf so I route down all the way down Leaving only a 1/4 inch of the Mdf left or do I only route down a 1/4 inch? Does anybody have a pic of theirs? I want to do a flush mount with no mounting plate..thanks again
