Brief Description:  Right Flap Brace and Aileron Gap Fairing

It's been several days since I primed the "inside" surfaces of the right flap brace and aileron gap fairing, so I got started on their installation. I got the flap brace riveted on before my self-imposed riveting curfew of 9:00 pm (photo 1).

Before clecoing the aileron gap fairing in place, I put a SLIGHT bend in each of the flanges in an attempt to alleviate the pillowing I got on the left one. Cleaveland's EF60 edge forming tool's rollers are too wide to fit on the flange, so I used my Avery model 1042 edge rolling tool, which worked fine. (I'd had trouble with this tool overbending thin edges on my HRII project; turned out to be the operator...)

I clecoed aileron gap fairing to the rear spar three times before it was time to rivet, The first time, noticed AFTER clecoing that I hadn't dimpled the flange for the top skin. After I unclecoed the fairing and took care of that little detail (photo 2), I reclecoed it to the spar only to find a minor interference between the inboard end and the inboard aileron bracket attach angle. It just wasn't accessible enough to file the edge, so I unclecoed the fairing AGAIN. Before I got the fairing clecoed back on for the THIRD time, it was too late to run the rivet gun. Even though there is great access for squeezing the fairing to top skin rivets, I'm thinking about using the gun and bar so I can hold the parts together tightly while riveting.
