Continuing from last time, I started by trying to rivet in the endcaps for the aileron pushrods. However, I quickly realized that I had not final drilled the holes to the correct size so I first upsized them to the correct size and did another quick debur of the holes. The manual hand riveter was painless and sufficient for these blind rivets. Then a quick scuffing of the exterior of these two assembled pushrods, a cleaning with acetone, and then a quick spray with self-etching primer. Van's support replied to my question about the tightness of the bellcrank brackets and the answer was actually not to attempt to bend the support brackets but to sand down the brass bearing (and the bellcrank brackets, if necessary) to achieve the necessary clearance. So I started by using a punch to knock the bearings out of the bellcrank brackets so that I could work further on them. This would also give me a chance to slightly reduce their outer diameter so that they don't fit so tightly in the brackets, which I had not sufficiently done the first time. Inserting the bushing into the chuck of an electric drill and letting it spin inside some sandpaper for a few seconds was enough to make the fit better. I also ran some fishing line through the empty wiring grommets (plastic snap bushings) of the left wing, to make it easier if I ever needed to pull new wiring through those holes after the wings are closed up. What's next? I need to finish refining the length of the brass bearings, run fishing wire through the right wing, and then work on the next set of pushrods.
