Brief Description: Same as before, but right side - 404/405 drilling
Repeat of the left rib/spar drilling as before of the HS-404 and HS-405 ribs to the spar. Second time I did this, so it was easier this time to. Same thing I did before, clamping the ribs in place, and a long drill to drill out the spar and ribs at the same time - less chance for the dreaded mised or extra hole! Photos show the joint of the ribs and spar after completed.
Then more hole enlarging and same as before. No major mistakes today either.
