Subject: RV7-List: Consensus On Finishing Back End Of Fiberglass Tips...
Dear Listers,
Here are some pictures of my recently finished Fin and Rudder
fiberglass tips, specifically highlighting my notion of mounting the
VOR/GS/LOC antenna on the top of the Fin. It came out very nice I
think and gives full access to cabling and antenna mount for maintenance.
But here's my question. Look at that last picture of the back end of
the Fin fiberglass tip and note the gaping hole. I gather from the
plans that it is kind of up to the builder whether to put a cover on
the back of it. My first question would have to be why the f***
isn't there one already molded on it like on the front of the rudder
tip? But, hostility aside, what's everyone's thoughts on finishing
these? I'm just thinking that my patience for fiberglass layups
hovers around zero and I can just see taking a totally sweet tip
installation and mucking it royally. But, I will if I must. I would
really like the back end finished off rather than gaping open like
that, but it might be something I could live with...
Thoughts?

Take a piece of paper and trace the outline of the opening on the paper.-
Then find a piece of fiberglass scrap, or layup some fiberglass on a flat
piece of glass and let cure. then use the tracing you made and cut out a pi
ece of the fiberglass. Trial fit it in the opening, until you get a good fi
t. Then glue it in and let cure. After curing use filler-to make a smooth
front.

This is a method used by a friend of mine on his radio control aircraft.
Obtain some soft foam rubber, tan in color and soft. This is open cell foam, AKA
a sponge. Cut a slab about 1/4 inch thick. Hold the foam against the opening
and trace the outline with a Sharpie. Cut the outline out making it about
1/8 inch oversize. Mix some 30 minute epoxy, found in hobby shops and available
in small quantities, and soak the foam in the epoxy. Wring out as much of
the epoxy as you can. Place the foam "rib" in place setting it back just enough
to put a thin layer of filler. Let cure, preferably overnight. When cured,
the foam will be very stiff and secure. Fill with filler of choice. An option
to this would be to add some epoxy to the fiberglass piece where the foam
attaches. This adds a little weight, but makes the foam more secure.
