Worked on right wing scarf joint some more—this is getting old. Finally got the fit I wanted then moved to the left wing. Picked up some 2” roloc sanding wheels. This seemed to remove the material a bit faster than the file method. Still took several hours to get it to fit smoothly. Spent a lot of time on these scarf joints. After I was close to done, I discovered a builder’s log with a different method. This builder cut the end off of the underlying skin to allow the top skin to fit flush on the spar. Here is a link: http://www.mykitlog.com/users/display_log.php?user=bpauley&project=84&category=1925&log=31908&row=72. Wish I had seen this before using the “file & error” method. If I were doing this again, I would certainly take this route. Tank testing on the left wing is done—after nearly a week, the water level just moved up and down with corresponding temp changes. Removed the manometer, then checked the torque on the tank attach bolts. All bolts were properly torqued. Then I added some torque seal as a reminder that this step was complete. Nancy helped me move the wing onto the table. Wanted to make sure I hadn’t gotten any water in the tank when filling for the test. There was no water in the tank-not even damp. Primed the rear right rear spar where I had countersunk for rivets earlier. Found a minor amount of filiform corrosion on the upper inboard skin trailing edge of the left wing. I cleaned it up with a maroon scotchbrite pad, then swiped an alodine pen across the area. Cleaned up the shop a bit and dug out the DRDT-2 dimpler. Next up is dimpling skins and ribs.
