Mint LP provides Stevenson Alignment

@billstevenson 

I recently bought a Feickert protractor. It is from the use of it that my observations concerning Baerwald, Lofgren and Stevenson are derived.

  
Good choice. If you're an engineer you will quickly realize how good this Feickert engineering. I have no reason to use any other protractors, i have no idea why people recommend that plastic Mint without PS ruler if the Feickert has all in one and much better quality for any tonearm in existence.  

In addition i would only add a magnifying glass and very good lighting.

There is a misunderstanding here.  The Mint LP is made of glass not plastic and if used correctly it is capable of greater accuracy in my experience than the Feickert, although the latter is very close, close enough in my opinion.  As you correctly point out it is a universal protractor and it is considerably easier to use.  OTOH, Yip supplies the Mint with two magnifying glasses one of which is lighted, which is a nice touch.  For hobbyists with multiple cartridges and/or multiple turntables the Feickert is the most practical option.  But for the last word in accuracy the Mint LP is the best in my experience.
As to the point of my original post that all Mint LP protractors are Stevenson, that is not correct as attested to by several respondents here.  I stand corrected.

I guess when it comes to accuracy in microns no one can detect it by ears, so when something is more accurate than Feickert i don’t know what to think (only some sort of UBS microscope comes to my mind if a person is so concerned about absolute accuracy of everything). I believe it’s irrelevant when we’re comparing precision tools like Feickert or Mint. Personally i’ve never noticed that Feickers is not accurate, it’s always spot on with 6 tonearms i’m currently using from time to time.

@chakster Sounds like "believe" is the key word in your last post. Have you ever tried the SMARTractor or the Mint? If so, and you don't observe a difference, I can respect that. Please elaborate. If not, it's sounds like your belief might just just be the bias of ownership and wanting to justify your decision. Not the high level of informed content that I usually see from you. Cheers,

@sbank i have had at least 4 different protractors, i hate those with the mirror, i’m not crazy to buy more expensive protractors than Feickert and as i said all i need in addition to Feickert is a lamp and magnifying glass. After adjusting of at leats 10 different tonearm and maybe 60 cartridges with Feickers i don’t see any disadvantages of this protractor and this is the reason i highly recommend it to the others. Also, as i said, i am the one who use many tonearms, and it’s so stupid to buy protractor for each tonearm if the Feickert can serve all of them with 3 different alignment methods. In my opinion this is a precision tool, the spindle hole in it is just fine for my Luxman or Technics turntables. The PS ruler is always spot on. 

You can advise people to buy a new protractor everyday, or a new one for each toneam and claiming you’re able to hear a difference in microns (in my opinion it’s just a waste of time and money), but i would recommend just one protractor for all toneams and all turntables for those who’re looking for "real" tool for reasonable price with all 3 methods of alignment, not just a piece of glass or plastic or paper.

Comparing Feickert to the original paper protractors provided by the tonearm manufacturer i can’t detect any difference.

People often overestimate a problems with cartridge alignment, i am here to add a bit of common sense. For the maniacs USB microscopes available on the market to check avymuth etc., but it’s not necessary for people with 20/20 vision.
