Brief Description: Notched HS-404 ribs and drilled HS-405 ribs.
I haven't done anything in over a week now because I had to wait for some coutersinks and a few other tools that I needed. Got started with dimpling the HS-702 spar and coutersinking the HS-710 & HS-714 angles. Then I measured and trimmed the right and left HS-404 ribs followed by measuring and drilling pilot holes in the HS-405 ribs.
