Years ago I bought a "90% finished"
project. The entire structure was
done before I got it. But I did make
cowling. It is much too heavy. My
crappy cowling will be replaced some
way to reduce the total weight.
I bought a good replacement upper
The cowling can be used but I have
to modify the area between the
canopy mating edge and the
cowling lip, with foam and
fiberglass as it is 3/4" too low
on the top.
Looked through the RAF plans very
carefully. I cannot find any info on
the construction of the area.
It must be there. Where ?
I need to raise the surface from 3/4"
on the upper surface to less to none
on the sides. I am thinking of a
flexible 3/4" or 1" sheet, wrapped
over the wet epoxy covered surface
and let set up, then sanded to shape.
Is this possible with polyurethane
foam? Or polystyrene foam ?
I think blue styrofoam is too stiff
to get a concave surface and does
now sand to a concave shape.
I will appreciate very much any
I am sorry that my computer sends
2 copies of this. I'll try to fix that.
