Dimpled left top wing skins

Removed material from the corners where they overlap and butt up against the tank skin so that they’ll lay flat. I used 60 grit sand paper. Then deburred all the edges of the skins and wing walk doublers. I deburred all the holes I drilled in the doublers too.

Dimpled the skins with the DRDT-2.

Made it through both left wing skins before my arm got tired.

Machine countersunk the flange holes where they match up to the doublers.img_2317

 

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.

More rib work

I set the spars on the work benches opposite one another and removed all the bolts.

It went a lot quicker when I remembered I had an impact driver in the tool box.

There are a whole bunch of bolts in the spars.

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.

img_2147

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

img_2148

I mixed up some flox and used it to adhere the doubler to the rudder fairing.

img_2150

I blind riveted it in place. I’ll clean it up with sand paper once it has cured.
