Countersinking wing main spars
Countersunk the left and right wing main spars as indicated on the KAI. That was a lot of holes - somewhere around the 750 mark! My battery-operated hand drill developed a wobble - looks like it may have a failed bearing. I switched to my trusty big electric drill, which is heavier but it despatched the holes three times as fast as the other drill, much to my surprise. So for other intrepid builders - go straight to a full-size electric drill on these spars.
