I spent an hour working in the shop tonight and then another hour cleaning / organizing the shop because it was a mess.
First, I riveted the top of the aft bulkhead (F-810B) with the squeezer. I wasn’t sure I was going to be able to get to all of those rivets with the squeezer, but with the long reach yoke, I got to all of them fairly easy. The outermost holes near the longerons I was able to get from the outside, the rest I was able to reach by going inside the middle hole.
Next I moved to the rear baggage gussets and finished riveting those. I used the extended yoke on some, then moved to the longeron yoke, and then the offset and bucking bar. Probably, the offset/bucking bar yielded the best results.
To finish, I riveted the remaining hard to get rivets of the Canopy Rail Receptacle (F882-1) to the F807B-1 bulkhead. I used the small mushroom head and a 45 degree bucking bar after I messed up the first rivet trying to use the tungsten bar because I changed its geometry to something less than 45 degrees. I drilled the bad one out and replaced it after bucking the other two with success.
