cartridge set up


last time i asked this question here i was advised to use my two points protractor.
i have n official one from ’well tempered’ arm turntable and arm which i use.
the suggested instruction i got here was if the the cartridge on those points tend toward the spindle to move the arm forward, and opposite if it tend to the other side.
the thing is that i got several time a strange result which on each of the points it tend to a different direction.
i think that there is a third factor , the angle of the cartridge on where it mounted (forgot how it’s called) , which can be can be rotate on my arm.
so i cant succeed to find the optimum set up.
will appreciate any advice/help.
is there a way to add photos?

it's a deferent company think in new Zealand with a bit deferent arm and turntable.
asked them and they answered they dosnt support the original one.
mine is not the reference but the classic upgraded.
 i am using the original protractor.
the pivot does not fix, you can move it, same with the cartridge on the headshell can be rotate to different angles.

I have the manuals for the Well Tempered Classic arm. Specified distance from the spindle to the arm mounting post is 9.2". Be advised that this is not the same as pivot to spindle, as the expectation is that you rotate the arm frame on the post until the overhang is correct based on the Well Tempered protractor.

I tried a number of cartridges, and alignment with the Well Tempered arm is difficult, especially with the lack of a real head shell. Not for the impatient or faint of heart.

Stone1, if you message me with your email I'll be happy to send you a PDF copy of the manual.
