That's why you do a trial run on the table and adjust accordingly(you cut
that part off!).

Hi, Al,
You couldn't be more correct.
BTW I have prepared a small downloadable Excel file in my site in order to
calculate that "big difference". To be honest this file should be adopted to
calculate the correct template length if you keep them far (1-2 cm) from the
foam during the cut, but nothing impedes to use this file for this purpose.
Ciao.
Tullio.
