During the week I've been able to mold the center of the bottom of the window frame.
It looks twisted because the bottom is not cut straight yet.
It's perfectly in the plane as it cured against the installed guide board.
I used a long styrofoam wedge shape to force fiberglass to stick at the top and on the reference board.
You can see the wrinkles of the plastic wrap.
In the pic the wedge have already been scratched out.
I will wipe it with acetone and fill the space with something.
A pleasant surprise is to see the curvature of the bottom slowly appear.
Once the wedge is completed and filled, I'll grind off this bottom edge, and will rebuild it with a lot of fiberglass. For not it's mostly resin an would crack supporting the window. I keep it for now as it hold the whole shape.
This is the kind of wedge shape I used.
Cut by hand with a razor blade at approximately the right angle (27°).
We are in the land of the cut twice measure never.

Told ya
This is the smae setup I used for the central part, two more layer come on top of this before I stick it to the frame from under.
Like that.
It's going really well, much better than I anticipated.
