Cleeds, with no friction of the stylus in the groove, there is no skating force. Head shell offset angle is one cause of lack of tangency to the groove that from a vector force point of view gives rise to the force that pulls the stylus tip toward the spindle. However without friction headshell offset wouldn’t make one single bit of difference, and there would be no skating force. That is the genesis of my remark. And by the way, headshell offset angle is not the only cause of the skating force as far as the geometry goes. Skating force is further augmented by lack of tangency to the groove wall at any point on the LP surface that is not on the two null points of a typical alignment algorithm. Only at those two null points is headshell offset angle the only cause of the skating force. Everywhere else on the LP surface the two geometrical errors that result in lack of tangency are combined.
In addition, you are so so wrong about tone arms that have no head shell offset angle.
There is a lot of wrong information and subjective opinion in the above comments. I hope the OP can sort it out. I would advise the OP to talk to a person that knows this subject, or to do some Internet research looking for the comments of knowledgeable people.
