Grand Rolers "knuckles"

[Roger Jolly]

Hi Don,
        I've had a great deal of success with a thick darning neddle, it
slips between the felt and skin a little easier, if you kind of twirl the
neddle it slips very nicely between the two surfaces. Liberally dose the
core felt with 50% rubbing alcohol and water and it will puff up the core
felt a little and make a big difference on the noise factor.
  Just another spin on the subject.
Regards Roger
