Started layout for tailpost install. Dropped plumb line from STA J/H to table, measured aft 33" to mark location for tailpost. Drilled 7/8" hole in table top to fix tailpost. Started level and grinding of longerons. With tailpost plumb, Measurement of STA H 3/16 short. DETERMINED STA J/H NOT EXACTLY PLUMB!!
Was using plumb line and looked OK from side. NOT!!
Reset top fuselage forward 3/16". Called it a night.
