Rough-cut hole in L wing for Duckworks light, using a Dremel with a carbide cutoff disk. Began opening up the hole using 1/2" sanding drum mounted in an electric drill, but they tend to wear out very quickly. Will buy a 2" drum sander this week.
Test-fit elbow fittings for pitot line (90-degree AN833-4D and 45-degree AN837-4D). Both will require washers against the ribs because these fittings were not designed for as thin an application as the ribs.
Surprisingly, I did not need a stiff drink after cutting this gaping hole in my beautiful wing...
... but TWO drinks did the trick. Seriously, it was no big deal.
