No pics today. The first day back at work was a little rough, so I skipped working on the main spars tonight and began preparing the ribs. This took much longer than I planned as my air compressor tripped the breaker several times. I had just moved it to a new location in the garage and I think I will move it back tomorrow. It never tripped the breaker before. Anyway, rib preparation will take some time so I figured breaking it up into several shorter work sessions will keep it from becoming tiresome.
