Hey all,
are the nylon rollers on the end of the flexarm assy'  supposed to be
grooved? Mine are not. I'm guessing that the intended action is to have the
arms fixed into the track, but maybe they are just pushed tight by a proper
tension??????? I'm about to either lathe up some new rollers, or fiddle
with bending the arms. Whats the gig?
                      Thanks
