Vertical Stab (2.5 hrs )
And so... The Build begins.
Start Sec 6-2 [Section 6 - page 2] , Steps 1 to 6: Cleco, Drill, Deburr and Dimple. Primed Front Spar and Doubler at their interface.
Don't have picture of parts just after prime but here's doubler riveted onto Front Spar in Vertical Stabilizer. Duplicolor self etching primer is green. |
Note: After reviewing Van's recommendations, many builder's logs, and discussion with several local builders, I've decided to prime interior components "minimally". ie ...at those surfaces with work affecting the Alclad coating (drilling, deburring, etc). And of course all non-Alclad parts such as alum. angles. I scuff w/ scotchbrite, clean with Acetone, then spray self etching primer. Started with Duplicolor, but plan to switch to Napa 7220 or Sherwin Williams GPB 988.
Sec 6-3: Scuffed powder coat on Hinges (prep for ultimate finish painting much later). See Plan Gotcha's at Vans Airforce forum. One of the ideas by other builders is to perform this action now, since harder to scuff for finish paint once hinges assembled permanently.
