Started the instrument panel installations by finishing the hole cut for the RAC LED Elevator Trim Indicator. Used a square file to remove the radius of the corners from the CNC to create perfect corners for the indicator, carefully removing material and test fitting numerous times.
The pilot holes for the radio stack are already #40, so it was just countersink that was necessary.
