Task: Continued fiberglass work on rudder
bottom and top fairing, left elevator fairing, and the HS
and VS tips
was the big day, where I actually laid the first fiberglass.
It was pretty straightforward. Lay out some plastic, cut the
fiberglass cloth into a square several inches larger than
the area to be covered, mix up some epoxy, pour it on the
cloth, and then sandwich the cloth in plastic. I then used
the yellow squeegee in the picture below to "wet-out"
the cloth. This means it gets completely saturated in epoxy
and turns from a white color to translucent.
Here is the first piece wet-out. Its sandwiched between two
pieces of 2mil plastic and satrated in epoxy. I then used
a rotary cutting tool to cut the cloth in half for each HS
Note the rotary cutter on the top right side. I then peeled
off one side of the plastic that was covering the cloth and
applied it to the fairing. After tamping it down to its final
form, I removed the upper layer of plastic.
Next I cut 4 pieces of peel-ply which is 100% Dacron cloth.
It absorbs any extra expoxy from a lay up. Too much epoxy
is just as bad as too little.
Then I applied the Dacron on top of the fiberglass and pressed
into its form.
Lastly, after about 2 hours of curing, I trimmed the edges
of the fiberglass. We'll see what it looks like in the morning.
also decided to split the forward portion of the bottom rudder
fairing. I didn't like how much it was stretching which caused
some edges to poke up. I cut it on the band saw, stop drilled
the end of the cut, brushed in unthickened epoxy, and then
filled with flox. Once its cured I will sand it smooth and
Lastly I sanded
down the tip of the left elevator. I then filled the area
with flox. This will all get smoothed out, glassed over, and
then a slurry of micro on top.
