This is the first of quite a few posts to catch up on a great week at home, working in the garage about half of the time. Basically, I finished the lower-mid fuselage this week. Step #2 had me dimple the top flange of some ribs. For some reason, I couldn’t get the squeezer into position without causing some deformation of the webbing and warping the edge of the flange. I was (and still am) too tired to figure out what was different, but I did decide to simply modify my #30 dimple die set by grinding a flat surface on to the dies. Works like a champ.

The step ribs were next. Despite thinking I had paid attention, I did manage to get the wrong ribs installed on the #2 and #5 positions. I drilled them out, swapped them, re-riveted and moved on. Note the marked clecos holding open some holes which were not to be riveted from a prior step.
