Some progress was made on the fuselage construction and the F-1206A bulkhead that was previously Clecoed in place was riveted onto the F-1222 and F-1223 baggage ribs using mostly solid AN470AD4-4.5 rivets.
F-1206A bulkhead riveted in place onto the F-1222 & F-1223 baggage ribs … only two pop rivets were used where the squeezer could not reach.
The short F-1206G-L&R ribs were also riveted in place unfortunately access was not good for squeezing solid rivets into them so they were riveted in place using LP4-3 pop rivets. The clearances were tight, so here again the rivet mandrels were slightly bent and the AEX wedge was used to set the rivets.

I’m almost embarrassed to admit just how much time was wasted trying to figure out a way to rivet the F-1206D bearing bracket assemblies onto the F-1206G ribs using solid rivets. I tried every yoke and squeezer combination and I just did not feel comfortable attempting the task. One or two of the seven rivets could probably have been done with ease but the others all offered unique challenges and the rivets would have been long and for those especially the squeezer needs to be on them as straight as possible. In the end, I felt the risk reward was too great because access to drill out one of the rivets should something go wrong was not good ... so ultimately used LP4-5 pop rivets per the plans to attach the assemblies.

Because of all the wasted time previously mentioned, only had time to rivet one bearing bracket assembly in place … so when work resumes in a few days, the remaining bearing bracket assembly will be riveted in place along with the F-1206H ribs that are now Clecoed in place.
