Is my anti-skating too strong.
What we have here is, it seems, that what one WANTS to believe - one WILL believe. A case of Cognitive Dissonance - maybe my own? Speaking from experience MC is correct that point A the stylus tip to point B the fulcrum of the tonearm bearing (horizontally) plus the overhang will create the skating force/pull to the centre of the record, the spindle. A case of basic geometry -. Either hokey stick, S shape, or straight tone-arm makes no difference in the equation. At all. Now, to damage a blank record by skating over it, you will need the kind of VTA and a steel needle of some old Victrola Phonograph - not a VTF of max 2.5 gram, my take. Maybe a damaged stylus will do at 5 + gram VTF...?!? 😏 BTW, I own an old DECCA test record with such a damaged blank section, which surely was caused by what I suggested above. Lastly, yes the idea of the cantilever deflection observation 'can' work, so long the compliance is reasonably/pretty high - and the tone-arm has at least some sort of lateral damping - or a slightly stiff(ish) horizontal arm bearing? At 16 cu (compliance units) and below, one will hardly notice any permanent defection. At 20 - 40 cu it will be visible and can/could be used to set the anti-skate force... This includes to watch out for the cantilever 'squiggle' when the stylus/cantilever/cartridge/headshell/tone-arm (avoiding more cognitive dissonance) is lowered by a damped arm-lift into the start groove.

Pointless threads always the longest on audiogon. Some people never heard about TEST RECORDS like Hi-Fi NEWS TEST LP, because there are special tracks for bias setting. But, check, it’s very simple. Some decent cartridges designed to track well at 1 - 1.5g tracking force, in this situation, especially with advanced profiles, the anti-skating force is so little like 0.5 - 0.75 |
