102. Q. When should rod brasses be reported to be reduced? When to be
lined?
A. Rod brasses should be reported reduced when they are larger than the
pins and are pounding and cannot be keyed up properly. They should be
reported to be lined when the key has been drawn or driven to its full
length and the brasses do not close together or are too loose in the
strap lengthwise of the rod.
