Machine countersunk the doubler plates. Also drilled the attach hole to 11/32 after this photo was taken. I need to pick up a 3/8″ reamer to finish the attach holes in the fork and doubler once they’re matched up and riveted to the spar.

Much progress on rear spar

Peeled the vinyl from all the parts. Did the minor cutting and fabrication called out in the plans. Cleaned up and deburred all the edges with file, deburring tool, scotch brite wheel, and sandpaper. Scuffed everything with a scotch brite pad.

Attached vertical stabilizer tip

I final drilled all the holes to #30, dimpled them, machine countersunk the holes in the fiberglass, and blind riveted the tip to the VS. I detached the rudder from the VS and put the VS aside. Won’t be needing it again for a long time.

I marked the rudder bottom fairing and cut the hole for the tail light with the Dremel tool.

img_2146

Used the sanding drum on the Dremel to finish up the hole.

I primed the outside of the doubler with SEM rattle can primer.
