Tapped the holes in the tie downs brackets. My tap set said the hole should be 5/16″, so I reamed out the hole first. Then I tapped down 1″. I happened to have a 3/8 X 1″ bolt, so I tested the threads. They work great. I’ve never used a tap before. It’s a very cool thing.
Spent the rest of the time on deburring wing ribs. Here’s a picture, just in case you don’t believe me. Don’t they look so deburred??
