Once you post a link screwy things start happening and you can't post further or make correction.(your bearing).
@skyscraper , to continue I think reflex clamps like the ones JA Mitchel and Sota make are your best bet after vacuum clamping. They are less of a hassle to use and are near as dangerous. Do they improve what you hear? If you record is not flat then absolutely. The brief alterations in pitch that occur are probably worse than the worst wow any modern turntable would reproduce.
"If the record is not flat." I am sitting here at my desk with my turntable directly to the right with my eye right at stylus level. A 180 gm copy of Take Five is playing as I type. It is sucked down tight to a very flat mat and platter. The cartridge is just slightly gyrating all over the place. Back and forth horizontally due to eccentricity of the spindle hole and up and down due to irregularities in the surface of the record. This record is actually pretty good. All these issues in tonearm design matter. There is no real excuse to ignore any of them. I suppose sometimes you have to compromise.
