Located and match drilled VA-146 center elevator bearing to center hinge brackets. Primed and VA-146 with Tempo Zinc Chromate and riveted to center hinge brackets. Drilled HS-710 and HS-714 front spar reinforcement angles to HS-702 front spar channels. Tapered and rounded ends of front spar reinforcement angles. Bent ends of front spar reinforcement angles to 6 degrees. This was a tediouis process! Notched and trimmed ends of front spar channels to RV-7 dimensions. The notches are started by locating and drilling holes in the middle of a bend radius - another tedious process! Deburred all edges of front spar channels. Bent front spar channel tabs to 6 degrees and test fit to reinforcement angles. After a bit of tweaking all is well. Marked all HS ribs as left and right, using a "vibrating pencil".
