After many weeks of slow progress (4 weekends in a row of travel, and a couple business trips), I finally am back to making progress. I have been working the easy aft bulkheads, but I bit off too many at once and it was hard to get motivated to prep and prime all the little pieces (including the 705 seat back bulkhead). I have all these bulkheads ready for longerons and skins. I still need to finish riveting the 705 bulkhead in the next day or so.
