Fuselage Longerons (18x9) - Preparation

2026-03-22

Similar to the 30x10 mm longerons prepared earlier, there is another set of eight longerons made of 18x9 mm strips. Same story, some strips had defects and I had to plan carefully to make the most of the material I had.

Length (mm) Available
3690 5
1920 4
1680 4
1250 2
1200 1

From these available strips, I drew up the following plan. After all, not too bad and the number of scarf joints required is manageable.

No. Recipe Length (mm) Rest (mm)
