Clecoed together, drilled, and deburred the rear spar components left and right. Cut out the hole in the doubler for the push rod. The top is after using the unibit and a file. Bottom is after sanding with the Dremel.
Countersunk the holes in one of the doublers as directed. You can see in the picture that the aileron bracket is going to get in the way of the left most line of rivets.
Pre-dimpled part of the rear spar top flange, where the doubler fork will interfere later. (I laid the doubler fork on there upside-down, but you get the idea.)
Finished up the prep for the rear spar so that the parts are all ready for priming.
Made a jig to help with wing rib fluting, and fluted some of the main ribs. The picture on the left shows the overall jig. On the right you can see how a lamp from above makes the string cast a shadow on the holes. Clamp in the rib, line up the string with the first and last hole, and then flute until the holes are all under the shadow. You’re done! It really does work great.
