Enlarged the holes in the cover support ribs to take the snap bushings. Dimpled the ribs for platenut attach, deburred all holes and cleaned up the edges, ready to scotchbrite. Match drilled the forward and aft centre sections to the forward and aft bulkhead. I did as Dan Checkaway match drilled his by lubing up all 4 main bolts and sliding into position before drilling, this will give excellent alignment. Drilled out and countersunk the centre section vertical bars. Cleaned up and scotchbrited the edges of the F-704H side plates.
