Anti-skate setting on Graham 2.2

Hi All - There's a lot about setting the antiskate, but not much on the following question.

Here goes - I've set up the Graham arm (VPI TNT w Kleos) and VTF and overhand ets are spot on. I then use the Cardas vinyl setup disk to set the antiskate by using the cool blank test track in the middle of the LP. I've set the antiskate so the cartridge stays in the middle without swinging out or in. Seems spot on to me.

So, the question is - upon cueing the arm up or down, the arm will swing towards the outside of the record - should this happen?

Because the antiskate weight counteracts the centripetal force towards the spindle, then the cartridge should swing outwards when not loaded by centripetal forces- so this behavior makes sense to me.

But, I've yet to read anywhere that this actually what should happen - that the arm should swing out when cued. In fact, I mostly read that that the arm should drop straight down when set to play a track - if so, then it seems to me that the antiskate can't be doing much.

So, I'm hoping someone can confirm. Thanks !

Hope my story helps, or gives food for thought.

I finally settled on using minimum antiskate( with bias weight pushed right in) on my Graham 2.2 (ZYX Airy3-SSB,2gms vtf/Audiomeca J4). setting by ear.

I tried without a/s and two smaller diy weights, but although the sound was appealing in a sense, I felt it was somehow distorted, with excessive dynamics. as if the stylus was not sufficiently controlled without a/s.

With minimum a/s, the sole a/s track on the "Ultimate Audio Test Record" was tracked perfectly.
There was no need to alter the a/s during play, as I need to do with my SMEV/Koetsu rosewood or Dynavector DV507/ Benz Micro MC3.

Audie.
