Internal Face Plate

I have cut out the Inner Face Plate Rectangle (12mm MDF) with a Circular saw; and quick basic mock up jig I have clamped together as shown Above.

The cut is straight, but for that ultra smooth finish I ran over it with a straight edge with a coarse grit sandpaper.

Using my printed template of the Button layout schematic, I have marked the center of the button circle guides with a pen.

I used a IRWIN 28mm hole plain to drill.

After drilling the initial Joystick Center Hole, I clamped the Joystick chassis to the Faceplate, made sure the distance to the edge matched each side, then used the existing holes on Joystick chassis as a guide where to drill for mounts.
