Deburred and smoothed the edges of the left inboard skins.
Ordered some hardware from Aircraft spruce in preperation to close the inboard wings.
Before closing the wing, I need to decide what to do about a wing tiedown point. AirWard sells a Onex tie down kit that uses a 5/16" anchor nut attached to the inboard main spar flange and screws an eyebolt into the nut when required. Sonex aircraft use a bracket attached to the main spar with an AN46-7A eyebolt attached for a tiedown. The factory Onex apparently drills a hole in the end of the locking lever as a point for a tiedown. This is not shown on the plans. So, a few options to think about.
Many thanks to Sonex builder Mike Smith for providing details about the Sonex tie down bracket.
