Started to work on the center fuselage. Drilled and deburred and polished edges and primed spar carry through. Riveted angles and gear angles to spar. Beveled spar bars. Pinned front and rear spar together. I will have to fine tune my pins as they are a little to snug. The 1/4 inch NAS close tolerance bolts for the gear angles are a little to tight to go in. I haven't found instructions to ream them but I think it will be required. Called Ed in tech to check but he was out sick. I am going to wait until I talk to him before I ream them.
