Match drilled #27 holes in Wing and Tip, then removed Tip from Wing to deburr and dimple the Wing for #6 screws. Used nutplate as template ( w/ #6 screw inserted from backside) to drill #40 rivet holes. Going well, but needed to stop for other errands today.
I chose to leave Tip installed so I could "match drill" #27 holes. Seems better than instructions which have you remove and do separately. Since the #30 size cleco's are a little loose, I left a few of the original #40 size cleco's installed (distributed top, middle & bottom) to insure the Tip didn't move.
