RE: Pickering UV-15 D2000-Q (pics)

I think that some of your problem may be the VTF - you wrote 1.3g. The D2000Q is intended for 2 ±0.5g IIRC.
However, it is distinctly possible that the elastomer HAS hardened. I have numerous Stanton and Pickering styli that I collected over the years that no longer meet specification.
The Quadrahedral is NOT a Shibata. A Shibata is characterised by 2 rear cuts on the cone which form a curving contact line which is forward of the centreline of the cone. The bearing radius of the contact line is either about 50 um or 70um (roughly) with the scanning radius polished to 6um If you were to do a section parallel to the record surface you get a heart shape. The Quadrahedral has 4 cuts with the 2 cuts formed on each side of the cone (which will be in contact with the record) and a section cut gives you a diamond shape. The line is on the centreline and is straight. The bearing radius is 76um and the scanning radius is <5um.
VERY different styli. The only similarity is that they are characterised as "parabolic" line contact styli.
