And what does the "1" stand for in the grade anyway? I know B means there
will be small (what does small mean in ply? ) patches.


IIRC "1" side. BC for instance would be both sides are the same species
but one side is a grade better than the other. B1 would be a B grade of
the species that you spedified on 1 side.



Hardwood plywood with an ANSI grading number of 1 or 2:

Provide sound surfaces with all openings in the veneer repaired, except
for vertical worm holes not larger than 1/16".
