Tonight I continued with the HS rear spar. First I finished the second reinforcement bar:
Then the two bars were clecoed to the spar channels and drilled:
I fitted the hinge brackets to the spar assembly and drilled the holes for the HS-708 ribs to #21 (all the rest is #30, the holes for the elevator bearing will be enlarged later):
And finally I match-drilled the elevator bearing assembly:
I want to prime the bearing and to do some touch-up of the holes in the powder coated parts, but I don't have any primer yet. So I will put the work on the rear spar on hold for now and continue with the front spar.
