Work continued on the left wing's rear spar this past week. Things seemed to move along nicely until I started counter-sinking the holes on the rear spar doubler.

I don't know if I was pushing too hard or the bit was defective, but the end result was the same--a broken countersink bit.
There are few things that are more frustrating when building than a broken tool. The good news is that the good people at Cleaveland Aircraft Tools had a new bit in the mail to me the next day. In the meantime, I was able to continue working on the rear spar.

This happens to be true vintage machinery. According to the former owner, this drill press was new when Truman was President and it spent its first years in the 4J school system as a shop class implement--now it's helping me build an airplane.
While waiting on the reamer bit to arrive, I worked to get the right wing caught up to the left wing. The nice thing about doing everything twice is that it goes MUCH faster the second time.

After I ream the critical hole in each spar and attach the rear spars to their respective wing, it will be time for Section 14 where the top wing skins are fitted.
