Completion of tail assembly

The rib 8 structure was attached to rib 902. When clecoed into place, it became evident that some shimming was required. A 0.63mm thick shim was fabricated close a gap between RF-RIB-801 and RF-RIB-902, and a 0.4mm thick shim fabricated to close a gap between RF-BKT-011.

It was noted that the AN3-5A bolt shoulder did not reach all the way through the two 3.2mm thick layers of RF-BKT-007 and RF-ANG-008. Also I prefer to have a AN960 under the bolt head. So I used AN3-6A bolts instead, with a AN960-10 washer under the head, another AN960-10 washer on the tail. An addtional AN960-10L (thin washer) was used on the tail to optimally place the nylock nut.

AN3 bolts torqued to approx 39 in-lbs and marked
