After a week long break due to cool weather and preparing for the Wild Onion & Eggs fly-in (that didn't happen), I've finally got started on my right wing panel. Today I marked my spars for rib spacing, installed the ribs and got them squared up on the jig. Visible in the second photo are the two straight edges I used to square up the spars and the plumb bob at the root of the spars. This is the same technique that resulted in a 3/32" difference overall in my left panel, so I'm using it again.
