2.9 hrs, 235 rivets.
Completed riveting nutplates to the main spars. Also bolted the tie down bars and bell crank brackets to the spars. Not final torqued yet.
After finishing the spars, took some time out for shop maintenance. Set the wing jig up to hold both wings.
And in a major advance, cleaned out the south wall of the garage so that the skin crate can be stored there. Now we can get two cars in the garage again! Since the daughter has practically moved out, I guess that second car is the wife's.
