Mint Protractor. A Pretty Nice Alignment Tool


So when I bought my Triplanar the seller had a Mint protractor for it. It was cut to be used on a Garrard 401. As luck would have it, the spindle size is the same as the one on my Scheu Analog table. So I put it on the table this morning, and fine tuned the cartridge alignment. My overhang was off just the smidgiest of a smidge, and I made the slightest of corrections to the cantilever alignment. Using an overhead light it was very easy to see the alignment lines. Playback showed the efforts yielded positive results. I have to say this is a good product. Nothing magical about it, just a clean execution of an arc protractor.

@rauliruegas is absolutely correct. Most tonearms are not at their specified spindle to pivot distance. They are off by several mm which throws the Mint out the window. There are way too many ways to create error when drilling for the tonearm. SME took this into account when they created their famous tonearm base.

In order for a protractor to be as accurate as possible the lines have to be vanishingly thin and there has to be a little divot to place the stylus in. The SmarTractor is a great example. It also gives you a choice of alignments, Lofgren B being the best for modern records.  The SmarTractor also allows you to accurately measure the spindle to pivot distance. So, if there is room for adjustment you can get it right on target. 

Mijostyn, is it really true that most tonearms are mounted incorrectly regarding P2S distance? I would have thought that overhang was the most common error. The very first and really only important thing to do when mounting a new tonearm is to get P2S as precisely as possible to the recommended distance. After that, setting overhang is a piece of cake. So why assume that the same tonearm mounted on the same TT in two separate instances by two different operators, will exhibit a difference in P2S? Bear in mind that I’ve never seen a Mint protractor, let alone used one. I guess what Raul is saying is that P2S for Stevenson is different from correct P2S for either of the Lofgren alternatives. Therefore, one ought not to use a Mint protractor to achieve a perfect Lofgren alignment, unless the Mint was specifically created for Lofgren A or B.

I sheepishly agree with fsonic on the minimal benefits of being anal regarding alignment.

Dear @lewm  : Not exactly that. What I'm saying is refered to how the MINT LP protractor was/is made it where ( independent of the type of alignment choosed ) the manufacturer takes the P2S distance as his protractor reference to build it.

I bought one about 10 years ago and never did like it, too difficult for my eyes. The problem with the Mint is that it’s pretty much turntable specific, change tables or tonearms and you likely need a new protractor. None of this matters as the consensus is that Mint is either out of business, or Yip is deceased. As far as protractors are concerned, I much prefer the Dr. Feickert, easiest alignment tool I’ve ever used.
