Of course Dertonarm is right that there are
. almost constant movement in microscopic dimensions of which we are not consciously aware.
How does that affect the ouboard tonearm pod in the Copernican turntable system?
Firstly lets look at the manufacturing tolerances achievable in the real world:
Some of the tightest tolerances available are +/-75 microns (a micron being 1/1000 of 1mm).
On the microscopic level, a molecule is measured in Angstroms (1/10,000,000mm), whilst an atom is approx. 1/1,000,000,000mm.
Now imagine the platter of your turntable, machined to the tightest tolerances of flatness and roundness with the tightest tolerances of spindle centring available?
In terms of molecular and atomic accuracy, the platter will deviate from perfect flatness and roundness by millions and hundreds of millions of molecules and atoms, whilst the centre of the spindle will be millions of atoms off-centre.
The record of course, not having its centre hole or overall diameter even remotely close to +/-75 microns in accuracy, will be wobbling its way around the spindle with gaps between its centre edge and the spindle itself, measuring hundreds of millions of molecules wide.
This manufacturing INaccuracy is repeated throughout the tonearm and its bearings which are slopping and rattling with gaps millions of molecules wide whilst the deflections and movements in the tonearm on the molecular level, resemble slow-motion images of earth-quake affected suspension bridges.
So worry if you must, about the microscopic movements being inflicted upon your turntable system
.but fear not for your proudly sitting outboard tonearm. It stands solid and immovable (the more mass the better) and the accuracy of your tonearm set-up will remain unchanged month after month as evidenced by we, who actually have them, can testify.
