I didn't think I'd get anything done tonight as I came home tired and unenthusiastic. Anyway after I got dinner going I went out to the garage and achieved a reasonable amount. I installed the last rear L angle for the baggage floor, removed it again and marked the aircraft center line. Installed the middle C channel stiffener and back drilled and clecoed. Installed the floor yet again and marked the rivet center line from the C channel onto the baggage floor. I'll drill the baggage floor to this C channel tomorrow night. Last but not least, I checked that the fuse is still square between the top former and the fuselage floor using a plumbob. Have I mentioned that this is the least enjoyable part of this project so far, I am fast getting to dislike the number of times the baggage floor has to be placed into and pulled out of the fuse.
