Cut eight ribs from quarter-sawn Sitka spruce stock (Aircraft Spruce lot 26-881, mill certificate on file). Rib-cap and web pieces fit into the jig without trim — jig indexing is running true after last week's recalibration. Glue-up with T-88 epoxy, weighted with sandbags for 24 hours. Ostrander stopped by in the afternoon to witness the glue process and inspect first two ribs for squareness.

Two 18-ft lengths of Sitka spruce, mill-certified, shipped freight. Inspected grain (≥6 rings per inch on both pieces), checked for runout — both pass the 1-in-15 slope standard from AC 43.13-1B ¶ 1-7. Stored in the shop loft at ambient humidity. This is the third spar-stock order for the project; older pieces are in the rack.
