January 15, 2009: Bottom Stiffeners & Nutplates & Bottom Skin...






Separated F-1204Z bottom stiffeners and F-1268A-E Doublers without incident. Be sure to mark the doublers to facilitate their correct placement. I used the nibbler that Jim Cone mentioned and it works very well to separate parts.

After this fabrication work, moved on to page 21-16 and completed the dimpling and attachment of nutplates around access holes. Step 3 on that page calls for breaking the edges along both sides for the F-1276 bottom skin. For this, I used the tool pictured, available from Avery.
