Cartridge protractor- the best?

More thumbs for Yip's arc protractor. Ie for the individual
combo TT-tonearm because the (different) dimensions of the spindle are accounted for.

Rockitman, The arc protractor is a replica of the arc the
stylus is supposed to trace (aka 'eff. lenght') along the
record. On the Mint tractor you have also the 2 nul points.
The spindle - pivot distance determine where one need to
drill the hole for a given tonearm. Ie the arc protractor
'assume' that the spindle-pivot distance is already correct. All 'ordinary' protractors are made with this assumption.

Hi Rockitman, I am sorry if created the impression to know
anything about Feikert. This is not the case. I wanted to
explain the difference between spindle-pivot distance and
the arc protractor. From your reaction I may assume that
you 'got the picture'. However a mirrored protractor is not as easy to use as you assume. Our eyes are alas not 'omnipotent'. And those short cantilevers and styli which seem to hide from us are a p.in the a. So some magnifying instruments are needed. But you should try the
Mint protractor. I am in this hobby for 40 years and have
never seen something better. I have two of them for both of my tonearms (Triplanar VII and the Reed 2A).
