cartridge set up

cant find this place

Try searching cartridge set-up .....
www.thetrackingangle.com
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. 

You have to find the specs for your new arm. Who mounted it??
If you can tell me the effective length of the arm (distance from pivot axis to stylus) I can tell you the approximate overhang. The Feickert protractor will work if you feel like spending the money. 

it's called "well tempered classic arm upgrade"
a new black platter and black arm.
i was on a trip to California around 1997 and collect it directly from their office in Palo alto.
with instruction how to mount it,
i did the mounting for the original and for the upgrading.
i am not quiet sure i understand your meaning of  "distance from pivot axis to stylus".
as  i said , the headshell which the cartidge mounted on has the option to rotate the cartridge.
so every different angle will give a different distance from the pivot to the stylus.
if there only an option here to upload photos .
here there are some pics.

on the instruction pages that i received for the upgrade it doesn’t say any thig specific for the overhang and rest of the set up.
only at the end of all mounting adjustment instruction: " fine tune all adjustments".
it can be interpret that nothing is changed compare to the original overhang instructions, but i can't be sure about it. 

I think WT, the company, still exists. From them you should be able to obtain the necessary specifications for your tonearm. From what you wrote I am not at all sure I understand its  provenance. But for any pivoted tonearm there will be a recommended pivot to spindle distance, stylus overhang, and effective length. To use any protractor that is flexible for all types of tonearms, including the Feickert protractor, you must have at least two out of three of these data points. So your job is to find those out. Also, if my memory serves me, at least the well tempered reference tonearm has fixed holes in its permanent headshell. And the tonearm mount is a single hole drilled through the chassis. So the pivot point is fixed in space and where the cartridge sits on the headshell, that also is fixed. More conventional headshells have slots that allow you to slide the cartridge back-and-forth to obtain proper alignment. In your case it may be that the only parameter you are able to adjust is headshell offset angle. That isn’t the greatest situation, but at least it limits the degree to which you can get this wrong. By the way, getting it wrong by a small factor is no big deal.

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.

well tempered labs is alive and well https://www.welltemperedlab.net/

as is toffco/mike pranka who is their distributor in the usa http://www.dynavector-usa.com/index.html

mike is a prince, has assisted me numerous times, knowledgeable and responsive

the upgraded arm is a bit different from the original classic.
i have the manual of the classic.
but i try anyway and will send you my email.
thank you

Stone1, I think the cheapest way to deal with this is a DB System's protractor. It will give you overhangs for various effective lengths. You measure the effective length by first centering the cartridge in the slot and setting the offset to 20 degrees. Next you measure the distance from the horizontal pivot axis (right between the strings!) to the stylus. Get the overhang from the chart on the DB system's protractor and set that by moving the cartridge in the slot. This is all approximate and does not have to be right on. It is just to get you close. Then you twist the cartridge to line the cantilever parallel to the lines at both null points. If you not do it this way then you will need to take the turntable to someone who can.
