Hi Dave,
thanks... Just had a look at the DUI repair ouline pdf.. and yes, now I see the "Installation ring"...
If I could get the proper dimentions of that ring - I could make my own.
If you have the neck opeing on a flat surface - inside out where you put the glue.
Without the hood - you have a pretty flat suitsurface (whith the neck
opening in the middle). Whith the hood - there is no opening, but the
buldge of the hood in the middle - and i have pull it through the new
neck seal - deforming it even more. I probably need to have a hole in
my worktop to get the hood out of the way...

out of the way. Instead of using tape to hold the suit, the suit is
clamped to the edge of the board with spring clamps. The seal is then
stuck on a DUI-style ring and installed in the normal way.
Pictures of the board setup and measurements for DUI-style installation
rings are in the book, but I don't have a copy handy now. However they
should fit the neck seal and the suit neck opening, anyhow, so just
measure both and make the rings to fit them. I have a bunch of
different sizes now since they are so easy to make, the DUI ones are
not always the optimum size for non-DUI suits or seals.
Unfortunately, I didn't have the book Vance refers to when I made
my first neck seal installation rings, but my measurements turned out
to be very close to the 10 5/8" x 8 7/16" DUI rings described in the
book.
Although I used 1/4" polycarbonate, it was still flexible enough. I'll
make my next pair from 1/16" polycarbonate to allow the glued surfaces
to be pressed together with more control.
I have the book now and, in my unbiased, unsolicited view, the book is a treasure of experience and techniques.
Anyway, I made a pair of rings, then decided to improvise by using a
disk instead of the ring for the suit opening. The concentric circles
scribed on the disk let me center the suit opening, since it didn't
seem to want to extend to the fully open width of the ring. Since you
have an attached hood, the rings are what you want to use.
The glued surfaces are kept separate with thin wooden slats while being
positioned, then the slats are removed one at a time to allow the
surfaces to be pressed together.
1/16th plastic would have flexed more easily with better control, but
1/4" worked fine. I managed to avoid trapping any bubbles between the
two glued surfaces.
I might add that the roller pictured below was flimsy and I've replaced
it with a stronger one with a metal frame holding the roller on both
ends.
After the last separator was removed and the surfaces were in good
contact, I removed the ring from the neck seal and thoroughly rolled
the contact area with the wallpaper edge roller.
