Nose Rib Riveting and Wing Skins

Over the past two days, I riveted the nose ribs to the spar and bent the leading edge of the skin.  I managed to put a wrinkle in one leading edge.  So I had to make a new one.  While I was at it, I cut most of the main wing skins (not the tips yet).

I measured the plans and drew two straight lines down the workbench to set the proper rib position from the spar.  I thought this was a really easy way to ensure they were all even.

Here you can see the spar and the aluminum angle for spacing.  The wood blocks are screwed down with two blocks on the back side too.


Here is a rib held in place for alignment.


Here are several ribs in place with drilled holes and 3/32 clecos.


Here is the finished piece (you can see the two lines I drew on the workbench pretty clearly in this picture.



I didn't get a picture of the bent skin, but I used Dave's method of pressing it down with a 2x4 after some encouragement from the Yahoo Group.  It was pretty easy.  The first one was wrinkled because I rushed it, and not because of the process.
