-Machine countersunk the rivet attach holes in the Outboard seat rib angles and F-806 bulkheads -Deburred, then dimple countersunk the nutplate attach holes in the arm rests. -Drilled the pre-punched holes in the mid left armrest, layed out the slot for the rear seat throttle, and cut it with a dremel. Finished the slot with a file and some sand paper...turned out pretty nice.
Driled the holes to 3/16", then layed out the cut lines
