Step 2: Finish all the edges of the R-1005 Rudder Horn. Final drill the two nut-plate attachment rivet holes, shown in figure 2, using a #30 drill. Countersink these holes, as well as the other two holes shown in Figure 2 for 1/8" rivets.

Step 3: Cleco the R-1005 Rudder Horn to the R-1004A Bottom Rib Half using the three holes shown in Figure 3. The R-1004B bottom Rib Half is unsupported forward of the last cleco which attaches it to the R-1004A. Use a "C" clamp to hold it in position with the R-1004A and the horn (make sure not to cover any of the holes on top of the horn). Lay a straight edge along the flange of the R-1004B to make sure it remained straight.

Match-Drill the six holes of the horn into the bottom rib halves using a #30 drill. Cleco the four outboard holes of this pattern and remove the clecos from the front of the horn.

Step 4: Deburr the edges of the R-1002 Spar (including the lightening holes) and the two R-107A Striker plates (which were set aside in section 6) then cleco together all the parts shown in Figure 4.

Step 5: Final-Drill all the holes common to the parts shown using a #30 drill. Note that the two nut-plate attachment rivet holes in the horn do not have matching holes in the spar. The nut-plate is attached, in a later step, to the horn only.

Step 6: Machine countersink the holes of the striker plates for 1/8" rivets, flush on the forward side. Make sure the holes of the striker plates are oriented as shown in Figure 4 before countersinking.
