Thanks again for still humouring me on this.
I get the skating force happening at the stylus and the interaction between friction and VTF: 100%. This describes the skating force.
But, as noted "Skating force compensation is provided at the arm pivot. This means that a torque is applied at the pivot..." So, the Anti-Skating Force is applied at the pivot: the pivot supports the mass of the tonearm and counterweight. Even thought the Anti-Skating Force is in theory a purely horizontal vector, does the mass of the system not even play into it?
I keep thinking that a pushing a perfectly balanced chopstick takes less effort than pushing a perfectly balanced tree trunk...?! What part am I missing?
