Ok, so family visits and lots going on mean I really didn’t have much time to “play” in the garage. I did get the blind rivet dimple tool, but it wouldn’t work on the ribs. Quick trip to Home Depot for some steel and I made the custom dimple bucking bar.
At this point I have the skin, spars, and ribs dimpled. (Didn’t seem like the spar needed to also be countersunk but will have to verify before I begin to rivet. The squeezer and substructure die combo looks like it was perfect).
Also countersunk the trailing edge. Again need to verify they were deep enough as I test-fit everything prior to riveting.
Maybe tomorrow night I may have time to do some more work.
