Continue c-sinking front spar. Evey 2-3 rivets I am checking for depth with rivet and caliper. It seems to be very hard to get consistent depth, probably due to narrow flange. Accuracy is around +/- 0.0005". About 3/4 through one flange of the spar Katya triped on the air hose and broke off pilot on the c-sink. Thats a good way to make Dad super mad. DONE FOR THE DAY!!!!!
