Finished deburring and prepping spar parts for riveting. I spent a bunch of time using scotch-btite pads and a 180 grit sanding block to remove scratches and get the parts to have a more even finish. I ma not sure if this is the best way. It took too much time to do by hand. If I could get a drill attachement or something I think that would be the way to go. NOTE: This entry covers work done over the past week, not just 10/10.
