Thanks to everyone whom helped with Fun with Lexan Part I, here is the encore.
Ok i've used a flush trim but to ensure that the Mounting plate for my trackball is flush with the rest of my cabinent (no exposed plate!!!) YAY!!!!, and i've drilled all the holes for my cabinent using a spade bit (button and joystick holes), and a holesaw (trackball), aside from a little sanding this thing is ready to be mounted. Which brings me to my next question.....
When i look at a lot of cabinents i dont see any screws on their CP. Either people are using really tiny screws or there is some method to mounting lexan that i dont know about. My original Idea was to use four main screws that Mount the Lexan, CP Art, and CP board to the rest of the control panel, and several tiny screws (outlining the rim of the CP) to secure the lexan, and Art to the CP board.
Is there a better way or is my idea flawed??
