Mint LP Best Protractor

I have the Geo Disk too.  Better than nothing.  

With the Mint the spindle-to-pivot distance is critical. The arc the null points are on gets flatter or steeper with the change in overhang. If it doesn’t measure exactly to spec and can’t be adjusted, give that info to Mint. He’ll make It custom. Just 2 mm off will render the Mint useless. That’s exactly how much my s2p was off. Fortunately for me my s2p was adjustable. Most VPI tables have incorrect s2p and have little wiggle room. Assuming the stylus is perfectly aligned with the cantilever, the Mint is as exacting as its alignment is difficult. Which is extremely in both cases. Here’s a tip for when you want to align a new cartridge: Fix the platter so it can’t move. Align the Mint to the cartridge already installed. Only then remove the old cartridge.

IMO the Mint is the most difficult alignment tool out there. It’s so exacting that any deviation of the cantilever is literally “under a microscope” because a minimum 15-20x loupe is mandatory. But what really sinks in after many hours on many cartridges is that it’s overkill. I find a standard protractor is much faster and results are equally good. I use a Feickert but any protractor that compensates for overhang should do as well.
