 |
|
I have finally attached the Tailcone Forward Top Skin (F-1074) and now I
need to fill in the gap between the cabin top the aluminum skin. This
is the method I was going to use to fill in the gap. I am also going to
use the same method to fill the side of the cabin top the the fuselage
skin. I am looking for comments.
First I will scuff the fiberglass and aluminum with 80 grit sandpaper.
Thoroughly clean the surfaces with acetone.
Apply a blend of west epoxy, cabosil and flox to fill in the low spots.
I will keep this fill about 1/8" low
Allow the epoxy mix to set up, but while still tacky then apply 2 strips
of fiberglass cloth cut on a 45.
Allow to cure over night.
Apply superfil to fair and fill any low spots
Sand and refill until smooth and fair.

Larry, That's exactly what I did, EXCEPT I did NOT apply the fiberglass
strips to these joints (I DID apply to all of the window joints). My
opinion is that I've yet to hear/see/witness any cracking along the pop
riveted seams, and the application of the fiberglass cloth is only to
help hide/minimize this potential. It also adds to the buildup and makes
fairing/blending a little more difficult. with the windows, your
basically blending /fairing only in one direction - away from the window.

Looks good, I did the same thing except skipped the cloth as I have my ideas
of cloth on aluminum causing cracks in the paint later.
I just filled with epoxy and flox/cabosil, sanded and final coat epoxy
cabosil, probably no different than the cloth in regards to cracking the
paint later but that's what I did.

Deems,
Did you cover up both rivet lines (the pop rivets to the cabin top and
the solid rivets to the bulk head?
