I am continuing with the drilling of the aft tunnel web today. I still have a few #33 holes to up drill to #30. These are the ones in the shear web. I’m going to use two #33 drill bits plus some silver clecos to keep things alight while I get two #30 holes drilled.
Welcome to my builders log for Sonex S/N 767. It won't be as big as a real 767 but if you scale the speed I bet it will be almost as fast
