I just remembered that transom is two layers of 1/5" lauan underlayment
laminated with plastic resin glue. Of course that's the same as bending
one layer of 1'5" underlayment. If you look closely at some of the photos
^^^^
and THAT should have been 1/5"

I also see your transom is not 22" wide but 22" high, and 26" wide. You
still can't have a 4" radius in a 26" wide transom.

To clarify... the template (to fit over the buck that I made) is 26"
wide at its widest point.... but this includes the radii + several
inches of material that goes back along the side before the scarfs to
join the transom and the sides. This maximum width is at is at the 12"
radius area..... at the bottom the template is substantially
narrower.... The area being covered is the surface of a conic section
and so the template looks like a piece of pie with the tip cut off at
a radius... let me see if I can do it in ascii art

Kind of.... with the scarfs along the edges. The bottom will be
bending around the tight 4" radius and the top around the 12" radius.
Does this make more sense?

I want the transom to look something like this when completed.

Jason Cajune (who builds the boats in the pictures) does masterful
work... and build the transoms by steam bending and torturing layers
of ply over a buck....

Ahhhh. I get it now, cool boat! Anyway, I still think you may need to
use multiple layers of 3mm. Even if you could bend the 9mm around the
bottom of the "cone" you would have to leave a lot of wood to get
ahold of, or use a lot of pressure which would mean making a pretty
good mold and press. Another way might be to use a couple of layers of
3mm with a layer of fiberglass inbetween and on each side. You would
not need to use thick glass, just want to make it a laminated core
type structure. If you are worried you could go with three layers of
3mm.
