Adjusted the flanges on the floor ribs and drilled the F804A flange, set up the F826 & 827 belly skins and started drilling them to the ribs and bulk heads. Everything lined up and looks good. I need to make a slight adjustment to the F807 bulk head but very slight. The floor ribs will need to be pushed into position to alight the inked lines with the prepunched holes. I'll need a helper for this. I did get the F815 ribs and the F806 bulk head drilled and the final location is established. I'll finish the drilliing process tonight and start the layout for the F842 rear belly skin. I'm getting close to having all the skins match drilled and in position. Soon I'll pull everything apart and debur dimple and prime.
