setting and riveting the back ribs

trying to wrap up some odds and ends and get ready to skin the left wing.  I’ve been putting off the back ribs becuase it requires unclamping the tip end from the jig.  It went pretty smooth.  I used the method I read in several other builder’s blogs on how to get the back ribs … Continue reading
