Spent a little bit of time cleaning up the ends of the root block and the landing gear block. The root block wasn't perfectly lined up during the gluing so the hemispherical cut out on the one end isn't perfectly lined up. It's not critical as this is strictly the transition at the end. The 2" holes for the landing gear shafts will be drilled after installation. They need to be perfectly lined up and that's best done in when it's part of the spar. Spent some time cleaning up the studs and plates that hold the wing mount in place in the spar. They were covered with paint and varnish. Additionally, some of the studs had cotter pins to hold the nuts in place. These cotter pins were rusted and need to be replaced. These studs are actually custom made aluminum rods with custom made aluminum nuts threaded onto each end. The nuts have a shoulder on them to fit into the holes in the plates. I have to replace a few of the studs that can't be reused. No big surprise, but there are no drawings for any of these pieces. My options are to replace them with AN5 bolts and making accommodations for the smaller diameter, or make some from aluminum rod turned down to 12 mm and alodined. Something to consider...
