A new way of adjusting anti skate!

I partly agree with MC, in that there IS no "correct" amount of anti-skate, because the skating force is a constantly varying quantity, as the stylus traverses the LP.  However, "some" amount of anti-skate is advisable, because all pivoted tonearms that are mounted such that the stylus overhangs the spindle will generate a skating force.  So, if you ought to have some anti-skate, and since anti-skate cannot be adjusted during play, we all take a wild guess.  Without knowing for sure, I would guess that the amount of anti-skate I use is about 10% of VTF, as Mijostyn so meticulously measured and applied.  But what I do to determine the amount of AS is listen to the lead-in grooves with zero AS.  This will usually generate some obvious R channel distortion.  (The skating force is at or near maximum at the outermost and innermost grooves.) I then add AS little by little until the R channel settles in and sounds like the L channel.  Then I light up a doobie.  The idea that I would spend $250 for an AS gauge is laughable, not because I don't like expensive gadgets but because there is no such thing as "correct" AS, except, if your lucky, for brief moments across the surface of the LP.

The accepted value is 9 to 11 percent of VTF at the start of the record decreasing slightly towards the center. The biggest variable is velocity (modulation.) The higher the velocity the higher the friction. You can only shoot for an average value.
Millercarbon is prone to extremes, "varies tremendously across the record." This makes him difficult to believe. 9 to 11 % is not tremendous. 
Lewm, anti skate can be adjusted to an extent during play. The geometry of many antiskating devises automatically lowers the anti skating force slightly as the arm traverses toward the center.  I used the same method by listening. It takes some fiddling to get it right. This method puts you where you want to be easily while setting up the arm. Psychologically it is nice to work to a number. But whatever. The main point is that you can do exactly what the Wallyskater does without spending $250. It is a product without a market. Rube Goldberg could not have done better.

There is video, I forget where i saw it, that demonstrates when you have adequately set anti-skate. It depicts the stylus in the dead wax, run-out groove, moving towards the label slowly. If it moves to quickly, you have too little anti-skate. I just follow the instructions provided with both cartridge and turntable and set and forget it.

Good for you MillerCarbon

There are LOTS of remedies out there for trying to measure skate. 

For AS, this looks credible. Certainly a way to check calibration of your arm’s AS mechanism. For THAT alone it’s worth checking!

Thanks!!
