The rudder had to sit for a week, in order for ProSeal to finish curing. That was OK, because it was a rough week at work, and there was no opportunity to work on the project anyways.
Today I pulled the rudder off the angle iron (straight as an arrow!) and installed the trailing-edge rivets. That angle iron made a really nice surface to rivet against. Also discovered that in one place where I needed to install an "oops" rivet (hole was enlarged for some reason) that the result was almost a perfect flush surface on the shop head side. Wonder if this is a best practice!
Next up was the elevator. After the first debacle with a screwed-up wedge, I made a jig for countersinking holes this time. See the photos below, but laid the bad wedge in the jig first and then inserted the new wedge. Result was that everything is level and stable for drilling.
Next came dimpling on both skins, using a vise-grip dimpler. Finally I used marine epoxy from Home Depot to glue the wedge between the skins, with everything clecoed down to an angle iron. Should be dry enough to rivet tomorrow night.
Total Time: 6 hours
