Not a lot of visual progress worthy of pictures today because I spent the day countersinking the main spar. First I did all of the nutplate attach rivet holes since they will need to be of a depth to accept a rivet head. Then I adjusted the countersink cage to go a little deeper and started on the skin and rib attach holes. These holes will need to accept a dimpled skin so they need to be countersunk a little deeper. I have a LOT more of those holes to go but hopefully I’ll be able to finish them tomorrow.

Like I said, not a lot of visual progress but this at least shows that we can fit a car in the workshop garage
