The wing is finished so it's time to start the fuselage.
You begin by adding the firewall and other bulkheads to one of the fuselage sides. Next you add the other fuselage side.
After adding the second fuselage side you add some triangle stock and doublers to strengthen the fuse.
Next is to sheet the bottom of the fuse from the trailing edge of the wing to the tail
Then you add the top fuse side sheet.
