I can only say that when I cut 3 or 4 fins from a sheet of balsa,
then clamp them to sand all the edges to make sure they are all the same size,
I am WAY far more than .025" off on the duts alone.
I do try to adjust for this by cutting the fins all 1/16 to 1/8 inches larger than the pattern.

Happy New Years!
