Step 6: Buttons:
You need to put some time into thinking how the button should be laid out. Some buttons that are needed are: a start button, a coin button, and others for various reasons. There will also need to be a hole for the joy sticks. The same size hole I cut out for the buttons worked for me. The best thing to do is to draw on a piece of paper and physically place your hands were the buttons would be, to see how it feels. Once the layout is done mark it on the control panel piece, and put the 1-1/8”inch spade bit into the drill, and start drilling. Here are some examples of layouts and I picture of mine:
Installing the buttons:
Simply push the button into place and the then screw the button into the nut on the other side. Just like a normal bolt and nut.
