I clecoed the F757T tip-up plates to the F705 bulkhead and longerons and measured / confirmed where the square holes needed to be drilled for the latch mechanism. Then I drilled 4 corner holes and used a unibit to remove most of the material. I finished up these holes with some files and sandpaper. I also measured and drilled all of the holes in the F695 gussets that will fasten to the longerons and upper firewall brackets.
