- Fiberglass Tips
to Log Index
Task: Started fitting the fiberglass tips
on the HS, VS, Rudder, and Elevators.
will start by making it known that fiberglass is really a
PAIN to deal with. Its messy and takes a lot of work to get
shaped and fitted correctly. I started by fitting the HS tips.
There were no holes in the skin so I had to measure in 5/8"
from the edge and mark a straight line. I then measured in
0.5" from the leading edge and marked in 1.5" intervals
to get 4 holes. I drilled the skin #45, enlarged to #40, then
match drilled the fiberglass tips. Using cleco clamps, I clamped
in a 0.5" x 4.5" aluminum strip that I match-drilled
for reinforcement behind the tips.
was the vertical stabilizer tip. The skin had predrilled holes,
which made it a lot easier. I had to trim the bottom flange
up to 0.5" to ensure a proper fit with the lip against
the skin. I then fabricated two pieces of 0.32 reinforcement
strips for the pop rivets to go through.
I traced the VS tip onto 3/32" balso wood I purchased
at a local hobby shop and cut on the bandsaw. Next I will
mix up some of our West Systems epoxy to glue in place the
balsa wood and reinforcement plates. It only needs to hold
long enough to lay a few layers of fiberglass down and hold
the slurry of 3M glass bubbles and epoxy mixure for filler.
