Cut foam ribs for trim tab. Based on other RV build logs, I did not attach the horn to the trim tab. Made the bending brake and completed the trim tab bend. LL: use piano hinge rather than door hinge. The space between the 2 leaves of the bending brake was to large to bend the trim tab. As such, I placed some shims on the lower leaf. Also, made template for creating end bend blocks as well as cut templates for v blocks.
