Cut, deburred, and marked both upper spar caps and both lower spar caps. 5/16" reference line called out in Step 2 marked on upper spar caps. Could not find cushioned spring clamps bought so that spar caps could be clamped to spar and match drilled. Need to find those before continung. Also decided to prime with Sherwin Williams Wash Primer P60G2. Figure if it's good enough for Van's, it's good enough for me. Still need to buy compressor later this week. Will probably pick up an air drill and spray gun as well so Section 06-02 can be completed.
