Fabricated an 0.020" aluminum spacer plate for pitot tube mount. Drilled and clecoed angle bracket to rib. Clamped backing plate and spacer in place to check alignment with inside of wing skin. It looks like it will fit perfectly now. (The spacer is needed because the joggle in the backing plate is made for earlier RV models with thinner 0.040" spars. RV-8 spars are 0.063".)
Cut aluminum pitot line for left wing and began installing through grommets in ribs. Began routing line around the base of the aileron bellcrank. Removed AN3-6A bolt from bellcrank and sized Adel clamp for attaching the line there. Will use an AN3-7A bolt as a replacement.
Drilled out existing lower grommet hole on one rib to 7/16", primed hole, and temporarily installed a straight bulkhead fitting (-4). Will install a 45-degree fitting later to allow the pitot tube to be removed and serviced easier. Will install a 90-degree fitting on the second inboard rib to allow for easier connection to the plastic fuselage line.
