A new way of adjusting anti skate!

Regards Lew(m):

Thanks for the gracious "hello".

You wrote: "a lot of so-called authorities have run too far with that ball, saying that headshell offset is THE cause of skating". I too have heard that. One might ask those audio gurus what would be the effect if the headshell were turned away from the spindle, would then skating force direct the arm away from the label? An amusing proposition. 

It seems to me that no matter which point of the compass the headshell is aimed or however the tonearm is configured, the axis from stylus to pivot (and as you mentioned, over/underhang) is the primary  consideration.

Peace,

There is no centripetal force vector that consistently aims toward the spindle. It has been a long time since I read Kogen, but if he claimed the existence of centripetal force in skating then he either was referring to a condition similar to the one in my first slide of the download (depiction of the treadmill), which is a minor component of skating force, or he used the term in a figurative sense, not literal.

The profile of the very tip of the stylus will have no impact on the force vector directionality but may have an impact on coefficient of friction.

By the way, Wally passed away in 2018. This is J.R. Boisclair. I did not use my name as my moniker not because I am "hiding" but because I felt I should make it clear that I have a direct interest in this industry and it would be best if you knew who was doing the posting. Most people know WallyTools and fewer know my name. Cheers!

Agree, centripetal force, in the Newtonian sense, is not the issue.  I am aware that the "real Wally" passed away a few years ago. I just figured "wally" was a reasonable way of indicating that I was responding to your post.

Hi Wally, i can measure with Adjust+ the harmonic distortion with a 1kHz tone (0dB - 11,3cm/s) Does it make sense to adjust antiskating for identical distortion on both sides? Does 11,3cm/s this corresponds to normal music level?

I am bewildered. Several points made defy logic.

Antiskating has nothing to do with offset angle? I suppose you could say that the skating force is due to proper tonearm geometry of which offset angle is one factor.

A straight arm with no overhang has little skating when it is tangent to the groove.

A 12" arm with a smallish offset has a lesser amount of skating than a 9" arm with more offset. 

The water skier outside the wake has created an offset angle. If Wally wants to look at it from a different angle, it is a free country, but looking at it as a function of offset angle is perfectly appropriate.

Poorly set antiskating does not affect the volume of either channel and does not move the center image. It effects the groove velocity at which the cartridge will start miss tracking one channel or the other. Miss tracking causes distortion, very annoying distortion.

Boy, is it cold outside! Don't forget your gloves and hat!
