Wings part 16

 Started today by making up all the ribs that have some special parts attached or match drilled.

The two wing root ribs get these nut plates.  Make sure they are on the correct side of the web. UPDATE: I made a mistake and installed two nut plates in each rib here.  The plans only call for one.  Don’t do what I did! Updated #2:  I put these nuplates on the rib that was untrimmed at the front!  I must have been drunk and rusty at building when I did this.  This root rib must have the front nose flanges trimmed!  Don't do what I did!

They also get these two doublers.  I think the nut plates are for the electrical grounds and the doubler is for the electrical connector.  UPDATE: I made a mistake and installed two nut plates in each rib here.  The plans only call for one.  Don’t do what I did!

Then this solitaire rib gets two nut plates on the tip for the AOA sensor.  UPDATE: Yes this one is supposed to get two!  Update #2:  Notice that I put these two nutplates on a rib that had the front flanges trimmed.  DUH!  This is a mistake.... Don't do what I did!

Matched drilled these rib extensions.  Pay attention which rib you match drill to, these extensions are different.

All done and riveted.  Plans tell you to put shop heads on a particular side of the web.

Next comes match drilling the hinge brackets and ribs to specific ribs.  

I then did the other two.
