Tonearm mount to the plinth vs arm board vs rotating arm board vs isolated tower

It’s customary to describe six degrees of motion as follows,

The y axis (vertical direction), z axis (first horizontal direction), x axis (second horizontal direction), plus three rotational directions, rock, roll and twist, around the x, z and y axes, respectively. (There is actually an infinite number of directions in the horizontal plane.) Let’s twist again like we did last summer! 🕺🏻 Think of seismic type forces moving the component like a wave passing under a boat out on the ocean.

Geoff, Enough already with the seismic forces. Have you figured out that no one is listening?

Hey, lewm - Blow it out your bagpipes, dude! See if anyone listens to that.

It’s bad enough we have to contend with the forces of the seism, now we have to contend with the forces of evil.  🦹‍♀️
