Brief Description: F704 Center Section - Initial Drilling
F704 Center Section - Initial Drilling of uprights. Drilled F704G spacers and CSK for rivets. Drilled all 5/8" snap bushing holes Note: edge distance of 5/8" bushing holes encroaching into uprights. Spoke with Gus at Vans and he indicated that this is not an issue and it is ok to relieve the uprights as much as 1/8". Of no concern. Good. Apparently Phlogiston has my pilot holes off from standard, by about 1/16" to the outboard.
