"The holes" refers to the holes in the skin that are common to the rudder skeleton as defined in step 6. The bottom row of holes where the fairing attaches is not touched in this section, rather in section 12, page 12-3, steps 2 and 3.

Step 1 instructs the builder to rivet together R-1004A&B Bottom Rib halves. This results in difficulty in riveting the R-1004 Bottom Rib Assembly to the R-1001-R Skin as instructed in Step 3 on Page 7-8. This is because of inability to get a rivet squeezer into the triangular converging tip between R-1004A and R-1004B (see figure below). Recommend delaying 7-7 Step 1 until after 7-8 Step 3. In doing so, there will be ample room to utilize a rivet squeezer. Otherwise, insert a chisel on top of the rivet and buck the chisel face to set the rivet.

• Consider using a metal angle / square steel tube with matched holes to get a straight rudder trailing edge during assembly.
• Consider using MDF boards instead, see this FB thread.

There are many ways to roll the leading edge. One possible solution is to get a white powder coated steel closet rod at home depot, then go to the tools section and find a socket that fits snuggly into it. Drill two or three 1/8th holes through the rod and socket (with a tungsten carbide drill bit) and pop rivet the rod to the socket. Using a socket wrench with a universal joint, you can easily exert plenty of rolling force into the rod. Tape the skin to the rod using heavy duty duct tape.
