Flew a lesson with Cliff in the 170 in the morning. In the afternoon removed vinyl and worked on deburring small parts for Section 14. Finished the areas lending themselves to the use of the 6" and 1" deburring wheels. Started hand filing and sanding the areas too tight for the wheels. Used sanding drum from Dremel set in the drill press to remove the deep manufacturing marks in the small inside surfaces of cutouts. Still need to work the smallest areas of the parts with crocus cloth and Scotch Brite, then prime. Pastor Pete stopped by for a look at the project.
