[CAUT] agraffes

[Karen Lindsley]

Willem,
I understand the usage of washers for aligning agraffes perpendicular to the
the strings; in this case there are visible differences in heights.  I'm
thinking of removing some of the washers and adding to others so the heights
are within a few thousandths of an inch.
