Worked page 7-7 @ steps 1 & 2. Cut trailing edge to correct length, and marked location in LH & RH rudder skins. Set up drill press to #40 Drill Trailing Edge. Used scrap Trailing Edge as wedge to orient 90 degrees to chord line of T.E. Got idea from VAF forum in the Gotcha's thread. [ see the xls file listed in Common traps and mistakes -- in this case, a builder documented this recommendation]

| Laser "crosshairs" really assist with initial set up at drill press. |
Step 3: Attach LH and RH rudder skins, horn brace, and Attach Strips to Rudder skeleton. Excellent fit of some complex parts, such as the horn brace.
Lots of clecos required to set up for Final Drilling #40 holes with reamer.
100% cleco along trailing edge. Worked from center outward toward top and bottom of rudder, alternately to provide minimum distortion. Pleased so far with straightness of the T. E.
Also match drilled #40 leading edge one final hole at forward flange. The fit of skins around counterbalance rib and tip rib seems really good.
Still need to complete one whole side.
