Checking Anti-Skate?

Some of the early 45rpm one-side pressings (remastered Blue in Orbit, for example) have a smooth un-grooved back side. But this is not the right way to set anti-skate because the skating force changes depending on the friction between the styles and the groove. The anti-skate force you need during normal playback is very different from the amount you set on an un-grooved surface.

Onhwy61, I actually use a 360 degree rotary builders level. I place it on the rack next to the turntable, set the height of the laser to the centerline of the tonearm (at the gimbal), then raise or lower the back of the arm, setting VTA. I can then confirm the adjustments by tilting the head of the builders level to match the angle of the tonearm. It then provides me with a measurement in degrees.

It is incredibly accurate. Although my ears are what actually confirm my adjustments, the laser is a great way to dial it in and get you in the ballpark.

And, you are not going to answer my question or just don't have any info on a measuring device?

I'm always nice to you......??????

Also, testing on a blank disc is invalid. Skating force is related to groove pressures/overhang. What you see with a blank disc is merely centrifugal force.

Sidssp, I know it's not right. But at the time, it was the only method I had. That's why I'm looking for a measuring device. Does one exist?

The skating setting is always a compromise between the lead and final grooves. I set mine by hovering the tonearm over the middle of the LP, raising and lowering the arm to see what direction it wants to go, then setting the skating where it tends to remain stationary. The stylus never even touches the record. Not precise, but hey, it's vinyl!
