This is Namiki Boron Rob cantilever/stylus structure
@scmIf you want to know the truth I'll tell you that genuine ZYX cantilever structure is not what anyone can get from Namiki or Ogura, at that time (Airy is an old model) it was made for ZYX exclusively, see on
my image why it's different. I owned Zyx Airy III.
Now you can look at
Namiki Boron in the real world, an actual image provided by Namiki. What you will see is a Boron Rod with an angle cut end and glue.
When you buy something used you must ask for an image of the cantilever and stylus, otherwise people can cheat you selling refurbished cartridges without even mentioning this fact. You could buy a macro lens for your smartphone to check it yourself.
Zyx cantilevever is completely different in comparison to others.
Nakatsuka-San used press-fit method (not glue like all re-tippers or modern Namiki). As you can see on my image (it's genuine
boron cantilever on my Airy III) the diamond goes all the way through the hollow pipe.
Actually in a present time
this image uploaded on
Namiki site, but when you scroll down you can't find this cantilever in their list of available cantilevers. There are only two type of cantilevers with press-fit stylus mounting method (aluminum and
zirconia).
