|01:09Gibson Mastertone banjos and most other Bluegrass-type banjos use one or two coordinator rods instead of a dowel stick to connect the neck to the pot. On these instruments, two threaded bolts protrude from the end of the neck where it attaches to the pot. They pass through corresponding holes in the rim. The coordinator rods have a female thread on one end that is screwed onto the neck bolts on the inside of the pot.
If only a single coordinator rod is used, the upper neck bolt is fastened by an ordinary nut. The other end of the rods are male threaded . The upper coordinator rod slips into a blind hole on the inside of the tailpiece end of the pot and a nut is used to apply pressure against the pot. The lower rod passes through a hole in the pot and has both an inner and outer nut that tighten against the rim. The tailpiece hanger is also held in place by the outer nut.
The rods can be used to slightly adjust the action by changing the tension of the upper and lower rods but this can have a negative effect on the sound of the instrument by disturbing the natural vibration of the instrument.
