Couldn't do much tonight, cause I couldn't get away from work till after 7:00. All I was able to do was to fit one more rib, BL 54.5. Actually the pattern was pretty accurate, so truthfully it took relatively little fine trimming to get it to fit. I'm not attempting final trim of the upper side, which is actually the lower skin side. I did turn last night's rib over, but am not really satisified with its fit in that configuration, so will probably just enlarge the lower vent holes a bit.
