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?

Try searching cartridge set-up .....

There are several different sites here.

You need to research for yourself instead of relying on others.

That is  called offset angle. If you have overhang set correctly you just twist the cartridge so that it is parallel to the lines at both null points.
thanks.
the problem is that i don't know the right overhang cause at the time  i have upgraded to a different arm , and the instruction i have is for the original one.
Buy yourself Dr. Feickert protractor, it's for all cartridge, all turntables, all tonearms. Choose the geometry you like (there are 3) and adjust everything properly. PS distance is measurable too.
