THE LOOSE NECK
A loose banjo neck will detract considerably from the sound of a
banjo because the instrument is no longer one solid unit and the
vibrations are not able to carry through the instrument properly.
A banjo neck can become loose due to adjusting the coordinator rods
and allowing the rod to turn when adjusting the nuts. Insert a nail in
the hole in the rod to hold the rod from turning when adjusting the
nuts to change the neck angle.
To do this you:
Place a nail through the hole in the coordinator rod to keep it 1.
from turning.
Loosen the coordinator rod nuts on the rod. 2.
Make sure the neck is lined up properly with the tension hoop. It 3.
should be parallel to the hoop, not skewed in any direction.
Place a nail through the hole in the rod and turn it tighter to the 4.
neck.
After the rod is again holding the neck on tight, adjust the 5.
coordinator rod nuts to re-set the action. See Coordinator Rod
Adjustment Section.
