It's the arc that a stylus tip will trace if properly set up on a particular arm. The geometry depends on the arm parameters, not the way the record was cut (which is done with a linear tracker anyway).Originally Posted by Patrick Dixon

Patrick i'm surprised you're not arm geometry savvy, a man of your skills. ;-)

It is if you're using one of those who-zee-muh-whatzit's you see in Clive's avatar, affixed slightly northeast of the platter.
Lyrics are the ramblings of man, sometimes inspired by The Creator, most often, not.
But music (melodies, harmonies, rhythms), that's God stuff.
Always was. Always will be.
One of the biggest lies ever told was that only certain kinds of people should listen to certain kinds of music.

I expect than a specific example of an arc can be a straight lineIt is if you're using one of those who-zee-muh-whatzit's you see in Clive's avatar, affixed slightly northeast of the platter.
I can't state too strongly how much easier it is to setup a cartridge once overhang is correctly set. Using a jig, whether Dr F or homemade, make the overhand setting easy too. Maybe I'm just useless at setting up cartridges but it's always seemed to me that using a 2 point protractor to set overhang (north / south) and angle (east / west) at the same time is fraught with potential for error. Setting north / south first hugely speeds to process when I exercise my inadequate skills!
Even with a // arm overhang is the first thing you set.

Oh I'm perfectly savvy - my point is that with a pivoted arm you will always have tracking error, so the only questions are where on the record it will be right, and how much out will it be elsewhere.
I'm therefore extremely skeptical that it matters that much in reality if you're a little bit out from someone's idea of 'correct'.

You make a fair point - often one is simply moving the position of the null points - they still exist, just not exactly at the arbitrary points Baerwald etc dictate. Offset angle is another matter.

Patrick, I assumed you knew. Truth is it's one of those down to personal taste things, do you prefer minimum EOS distortion and are willing to trade that off for a null further in from the start of the record and higher SOS distortion, or do you maybe prefer lower RMS distortion and align accordingly.
Fortunately because I' m generously hung it's not an issue for me.
