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

Hi Bas, Yip from the MintLp has the data of the most TT's
and tonearms. You should ask him first. I ordered two protracors for my Kuzma Stabi Ref. + Triplanar + Reed 2A.
He needed only the data about the Reed.

I use both for my JMW 10 arm wands. The VPI jig will allow you to quickly and easily set overhang and overall cartridge geometry.

The MintLP protractor will allow you to align the geometry to the cantelever, as opposed to the cartridge body with the VPI jig. It's a very useful tool and well worth the cost, IMHO.

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.

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.
