Brief Description: Flaps - Install platenut to inboard rib
Then I decided to rivet the inboard rib with the platenut and doubler. So I clamped the platenut in position and put a 1/4 inch bolt thru the hole and into the threads to keep the platenut centered. I decided the .25 hole was to tight and so I enlarged it with a 0.257 drill. Now the bolt is not so snug in the hole. Then I riveted the most aft hole with a 1097 rivet which has a nice small head and requires only a little countersink. You can but this little box of 1097 rivets from Avery. I squeezed the rivets.
