I got around to cutting the rear blocks for the aileron ribs.  That is, the wing ribs in the aileron area. 

But I ran into a problem.  When cutting the curved portion of the block, the router was ripping the blank off the jig.  Pulled the nails right out.  So I rigged this up for cutting the curved part.

Once the curved part was cut, I could move the clamp, so it wasn't in the way of the router, and complete the cut.

And, finally, finished blocks.  I spent the rest of the evening cutting the gussets associated with these blocks.
