6.6 hrs
Long day, lots of forward fuselage progress. The morning started out very nice for a change. We've had a brutal July and August, sitting at 67 days of 100 or more degrees. 2 short of the record set in 1929. The garage faces east, so the Sun heats it up fast. But it was much more pleasant than it has been for the last three weekends.

Twist, fit, drill, and cleco 713 aux longerons. This went smoothly. I found that twisting the angle just short of 90 degrees fixed just the right amount of twist.

Finish making 719B angle clips. I'm certain that other builders have commented on this, but don't drill the hole in the vertical flange yet. If you do, the only way to match drill to the firewall stiffener is to clamp the 719 to the fuselage stiffener as best you can ( there's not enough room to get a real clamp on it), and take out all the clecos in the 970 to about a foot back. Then you can flop the 970 out enough to get an angle drill in to do the match drilling. That's what I did. It wasn't that big a deal, so maybe it's not so bad. But I just didn't like the security of the clamp, so I think it would be best to not drill the hole until it's all fitted, and then match drill from the inside of the firewall stiffener.

Finish making 917 lower longerons. Used the bandsaw, belt sander, die grinder, and file to trim the aft end down. It turned out OK.

Fit, drill, and cleco 713 longerons and 719B clips.

Twist, fit, and drill bolt holes in 917 longerons.

The garage is covered in aluminum shavings now!
