Brief Description: Flap Mechanism 16 Rivet on doubler
The drawing says to enlarge this brace hole to 5/8 to clear the bolt head. Why? Anyway this is the 1/4 hole that had a little chatter marks on it, so I'll follow the directions and enlarge it. I kinda like the looks of the bolt head being recessed slightly.
Dimpled the holes and countersunk the holes in the doubler plate and riveted it on.
