Sect 12-03 - Added Rudder Fairing Doubler (alum) to Rudder Bottom ...to ultimately mount LED taillight. This is last major step involving the Bottom fiberglass - so drilling and cutting into this area now was a little intimidating. (don't want to start this over!) So proceeded cautiously...and it turned out fine. I was extra careful tapping the small 4-40 threads in this thin doubler...especially aluminum. Not convinced these threads are robust...so I'll be seeking some alternatives to re-inforce.

| Set up for tapping 4-40 threads in doubler. I hand turned chuck while applying steady modest down force. Whew...A-OK ! |
