Elevators 9-1 to 9-2-7
Starting on the elevators, I began by marking and cutting the 16 E-1008 elevator rib parts into pieces using the bandsaw. I then deburred all the edges using the bench grinder wheels on edges that I could easily reach, and then a scotchbrite wedge attached to a dremel for the remainder of the edges.
With everything deburred, I clecoed the ribs together and made sure the parts were labeled correspondingly. There was no need to final size the 1/8" holes as they were already final sized.

I then moved on to preparing and constructing 2 tip rib assemblies. This involved ensuring the tip rib flanges were at 90 degrees to the web, and fluting the flanges as required to straighten the ribs. Fluting was crucial here because otherwise when the ribs were clecoed together with the counterbalance skins, the holes would not line up if the ribs were not straight.
Ultimately, the fluting was not hard and the smaller tip ribs actually came already fluted and straightened, so I only really had to handle the longer ribs.

Next I final drilled all the holes common to the webs and flanges of the tip ribs except for the few rows of holes at the end of the counterbalance skins as directed.

The next step had me separating the E-1022 shear clips using the bandsaw, and then deburring the edges on the bench grinder. The holes in the short flanges were already final sized so there was no need to drill them, just debur them.

I then went back and finished off this section by deburring the edges and final drilled holes of all the tip rib parts.
