Waiting for epoxy to dry on right elevator trailing edge. Beginning assembly of left elevator. Match drill reinforcement plates to left spar (already done earlier, but double checked.) Cleco E-902, 905, 907 (spars and rib) to left elevator skin. Drill out bottom holes to main spar for cs 4-4 (blind rivets) to #30 Attach CB assembly and drill out holes (#30 for rib to spar attach) to #40. Only holes left to drill are the root rib to spar.
