Again here , 2 days of prep work, that is making some reinforcement plates, cutting, fluting, straightening the floor ribs as per plan.
I had respected carefully all the plans measurements. I also measured the distance between the main spar and the rear spar on my wings and the distance on my fuselage between F604 & F605 is perfect ...
Next time, I will complete the floor ribs adjustment, attach it between the first 2 bulkheads and start on F606 installation.
But up to this point, it seems to work well, at least so say my measuring tape.
