Dee,
 
Do you find the cell size is uniform across the comb?  Nowadays I tend  not 
to use foundation beyond shallow starter strips. I find the bees draw a  range 
of cell sizes ranging from 5.1 or 5.2 in the core of the brood area to  about 
5.4 - 5.7 in the upper corners that are mainly used for storage.  My  bees are 
local mongrels of probably Amm and Aml and I am situated in southern  England 
at about 51 N.
 
Chris
