Over the past week continued with preparing parts for left elevator. Matched drilled the spar, trim spar and flanges. Dirlled all bottom skin to spar hoes to use blind rivets. Went back and did same for right elevator. Match drilled skin to elevator coutnerbalance sub-assembly. Counter sunk top of E-907 elelvator trim spar. Did this very carefully clamping spar to piece of angle aluminum and table endge because trim spar is minimum depth for machine counter sinking. Dimples all parts for both right and left elevator.
