RE: Anti-skate help needed please!

Regards, JCB2005: Isaac Newton describes centripetal force as "That by which bodies are drawn or impelled, or in any way tend, towards a point as to a centre." This is not a constant. On a horizontal plane, frictional coefficients and offset, as well as distance from the center of rotation affect this force. Centrifugal force is the opposite. This is the force that, acting against gravity, maintains a satellite in orbit.

Stylus overhang is a factor. This might be illustrated by drawing a straight line from the position of the stylus at, in this case (we're not talking about alignment here), the two most usable points, those being the first groove and the last (another moving target). Now visualize the arc transversed by the stylus at the end of a pivoted arm, it should intersect the previously drawn straight line at only the two points terminating the straight line, something like this: I). Where the point of maximum departure from the straight line actually develops depends on the interdependent influences of tonearm length and overhang (effective length). If one thinks about it, it might be seen that these forces reverse when the stylus traverses the center of the arc, visualizing that it isn't necessarily in the middle of the distance traveled, somewhat like rolling a marble across a tilted bowl.

A ballista is an ancient weapon powered by twisted strands using two levers with torsion springs instead of a prod, the springs consisting of several strands of twisted rope (Wikipedia). From your description and photos, it appears there is too much of this torsion (anti skating) applied and it seems to be relaxing (unwinding) as the stylus approaches the inside grooves. It looks like you've wound your tensioning/anti skating adjustments in the wrong direction, whatever it is you've done you might try the reverse application.
Peace.
