Mint Protractor for VPI JMW 12.6 tonearm

Hi!
I want to order a Mintlp Protractor, but i can not find any exact effective arm distance from pivot to needle. I have seen 300 mm , 301 mm and 302 mm. What is the good distance. From centre pivot to front of the arm i am measuring 31,6/31,5 cm.

Hope you can help me out.

Cheers Bas

Just tell Yip at Mint LP to use the same geometry that I provided him for the JMW 12.7i tonearm. The 12.6 & 12.7 use the same geometry. The 12.5 is a longer arm. Here are the 2 links you need. This project took me a month to complete.

Nominal Effective Length - http://db.audioasylum.com/cgi/m.mpl?forum=vinyl&n=923584&highlight=jmw+12+7+ nominal+effective+length&r=

Yip should already have all this - I sent it to him directly.

If it were me, I would just use the free Conrad Hoffman protractor. It is just as good as the mint. It does not have a mirror finish.
