February 4, 2009: Section 22 (Continued)

Page 22-02, step 7 was completed. Fabricated the F-1288 Cooler Stiffner by removing excess material from the angle bar and deburred.

Step 8, Riveted the cooler stiffner and nutplates to the firewall bottom.

Step 9 was a bit confusing because it is difficult to tell in figure 4 what the perspective is. I thought I was looking at the inside of the tunnel assembly. Checking the forum where Mich48041 (http://www.vansairforce.com/community/showthread.php?t=36239) identifies this "optical illusion" and points out that you are looking up from underneath, looking at the bottom. This helped! On to step 10 on Saturday.
