Soory, Be, no matter how I
look into it I can’t understand why circumference force would make the arm to
move inward. If you spin your platter not at 33 but at let say 45 and pule some
light subjects on the platter then they will be thrown off the platter. A
needle and a tonearm are the subject of the very same forces and this is why LEFT
side of the needle worn more if anticaking is not enough. The platter spins clockwise,
so the needle left (the external) side pushed by circumference force press
harder to the left side of the groove. It is not a surprise that the left side
her more distortions and trucking problem when anti-skating is not enough. When
you make a left turn at high spin then your car rolls over it’s right side- or outside
of your driving trajectory…. Right?
