I need to make an exact pattern for the instrument panel top I am adding. THe top will be made of 1/64" plywood and glued in place after it is completely finished. This will make for a very good appearance and will make the airplane stronger than the plans call for in this area. I first made a pere pattern, then made a pattern out of chip board. This was then checked for correct fit. Finally I transferred this to the plywood and cut the piece out with a scissors.
