Yeah, more sanding. But then for something different I remounted the aileron and discovered that I had to modify the outboard bracket nutplate that I had created last month. This was the first time I'd mounted the aileron since then and I hadn't fully tested everything for fit at that time. Oh well. A bit of backwards to go forwards. Once the aileron was mounted I sanded the stub ribs between the rear spar and the front of the ailerons. I made sure there was sufficient and even clearance at each rib.

I took out a sharpie marker and outlined the rib stitching patches and reinforcements on the covering. I think I'd taken a picture of them previously but they were very hard to see with the heavy coat of paint that was on the fabric. It's very easy to see now and it will be helpful when it comes time to recover. The aileron was covered with one piece of fabric. The bottom was covered first and wrapped around the leading edge of the aileron and cut about an inch above the centre line of the aileron. The fabric was pulled over the ends of the aileron and glued and then the fabric was wrapped around the trailing edge and forward to the centre line of the aileron. The fabric was pulled down over the ends and glued to the ribs near the bottom surface.

I replaced a rib stringer that had been cut at one point. I wasn't pleased with it and I finally got around to splicing a new section in. It didn't take that long to do. I don't know why I put it off for so long.
