Geoffy the fuse troll has resurfaced as geoffy the static troll and in other recent threads, geoffy the directionality troll. He is a champion of twisted thinking.

The primary cause of the skating force is the friction force between the stylus and the modulated groove. A skating force is generated because of two factors: (1) the headshell offset angle, and (2) lack of tangency to the groove, which pertains everywhere across the surface of an LP except at the two null points that are created if one follows any of the accepted alignment algorithms. At the two null points, the cantilever is tangent to the groove, but because of headshell offset, a skating force is generated. Thus, there is always a skating force all across the surface of the LP, although it is constantly varying in magnitude. These conditions apply to all pivoted tonearms that are mounted such that the stylus overhangs the pivot and which also have headshell offset. By the way, centripetal or centrifugal force has NOTHING to do with the skating force. The primary cause of static charge build up on an LP is NOT the friction between the stylus and the groove. Those are my only points. Mijo, if you have data to dispute the second statement, let’s see it. |
https://www.maplatine.com/en/content/267-how-do-you-reduce-static-electricity-on-records- Good advice. Carbon fiber brush and anti static sleeves work well for me. Had a Zerostat back in the day. It worked. I’ll buy the theory that the different cart configurations result in static electricity being conducted away to different extents. |
The tendency of the stylus and cartridge to be forced inward on a blank section (for which their is virtually no friction) of the record illustrates that friction is not the driving force, it’s the centripetal force. In the case I just described of the blank section, the force of friction is actually toward the outer edge of the record. The innermost side of the groove wears faster than the outermost side if there is no anti-skate mechanism. That’s due to the centripetal force. As I already said, the force of friction due to the stylus riding along the groove is tangent to the direction of motion toward the center. So the force of friction has no inward vector. Hel-loo! This is an obvious case of monkey see, monkey do. 🐒 🐒 🐒 |
