A new way of adjusting anti skate!

Cant believe all the negative Nancy's on this thread.

The OP provided an interesting methodology to measure antiskate force.

The methodology can be used for whatever you believe antiskate should be 10%, 20% or whatever. 

Van den hul specifies a recommended antiskate value for his cartridges.

Furthermore one of the most positive aspects of this methodology is that you can use it to verify how accurate your antiskate mechanism is on your tonearm.

From my discussions years ago with the like of Van Den Hul and John Garrott of the Garrott Bros, uneven stylus wear from incorrect level of antiskate is a common problem. 

Any suggestions on how to get it right should be a positive.

I read it that all you do is balance the arm vertically to zero so that it floats.

Use your scales at 90degree hold out at the edge of the platter with the scale just above, and then if you apply antiskate the arm will pull towards the scale.

Using the finger lift hitting the scale is close enough to the stylus tip to get a good idea of how much antiskate to use.

If your weight is too heavy just use a small nut for testing ( weigh it on scales ).

Then I would suggest ordering a small one from Triplanar once you have worked out the optimum weight.

I am not at all sure I am correct, but my best explanation is that in tracing the tortuous groove, the stylus is pulled along at a "speed" dependent upon the platter speed and the distance of the styus from the spindle. The ins and outs of the groove walls however cause rapid instantaneous changes in stylus velocity, in order for it to negotiate the groove. Each instantaneous change, because it forces a change in velocity at the stylus tip, is an "acceleration". Acceleration is defined as a change in velocity, up or down. So now you have a mass (the moving mass of the cartridge) that is constantly accelerating. This would create or rather require the stylus to endure tiny forces according to Newton’s First Law of Motion (F = ma). It is those tiny Newtonian forces, which have a vector direction in the general direction of the friction force, that add to the net skating force.

Then could you explain why if you put the stylus on a glass platter or blank vinyl disc, neither of which have a tortuous groove, the skating force still occurs ? 

 I don't use anti skate with carts which can reach 60 microns

tracking ability test. 

Perhaps you could save money by asking a retipper to turn the old stylus around so you can wear the other side out before you put a new one in.

Where's your sense of humour ? 

@nandric

So you think if you lose an argument on an audio forum, then no-one will hire you as a lawyer. Perhaps some of your recommended reading on philosophy, reason and logic might need to be revisited.
