Brief Description: Inside Layup & Install Upper Longerons

Thanks to Jason & Steve for helping today with this layup !!! Shop temperature was set 26 deg C and the humidity was 38%. 1. Dry micro was applied to holes, transitions, corners, edges, and any area needing repairs. 2. Applied micro slurry over the entire surface of foam except the fuel sight gauges. 3. Layed out the first layer of UND cloth at a 30 deg angle, keeping the fibers straight; butted (not overlap) adjacent strips. 4. Wet out with excess epoxy on the first layer of UND cloth. Squeegee & Stippling. 5. Placed the second layer of UND cloth at 30 deg angle crossing the first layer. 6. Wet out with epoxy and squeegee well to remove air between layers and excess epoxy. Used a paint brush and lots of stippling. 7. Scissor trimmed and applied peel ply along the lower edges. 8. Scorr trimmed and applied peel ply to the landing gear attachment areas. 9. Scisso trimmed the tops as flush to the foam as I could (will have to do some cutting/sanding here later). 10. Covered spacers with wax paper and inserted between fuselage sides at the premarked locations. 11. Applied wet flox to the surface location for the top longerons. 12. Placed the top longerons in the premarked locations. 13. Added bricks to ensure the longerons would stay in position and there would be no gaps. 14. Checked for excess flox to cleanup but there was none. 15. Applied peel play on the glass alongside the longerons. 16. Using a light we did a final quality check to ensure no air bubbles or dry areas. 17. Layup left to cure at 25 deg C til tomorrow.
