A Copernican View of the Turntable System

Dear Chris, "I rest my case as Nikola would say''? I 'would' if I was able to to understand the connection between the 'mathematical symplicity' of the tonearm geometry and the actual state of affare in adjusting the damn thing(s). So I started a separate thread to please some German friend of my as well to 'enlighten' the 40 years of 'darkness' in my life. As Halcro 'would say' the 'heliocentric illusion'.So I am waiting for the promissed
lecture or/and enlightment.

Regards,

Oh my, oh my. I 'see' Lew for my 'mental eye' shouting:
'I knew I was right with my galleons!'But my position is different. I at last 'grasped' what the religion is about. But if anybody is free to choose his own religion and even
his political preference, why should this be different with the 'world outlook'? My quess is that some very strong feelins are involved. Well I care much about my armpod.
So if the 'heliocentric world view' or the Greek orthodox kind of religion to which I belong by burth, is more accomodating than my choice should be obvious. But it hurts
when someone who you regarded as a friend can do such thing to you. I think that Kant should be blamed for this.

Regards,

Dear Nandric, - yes, science is a cruel misstress and the physic laws which apply to the circumstances on this particular planet aren't always to my liking too.
I really hate gravity for instance ...;^) ....
Cheers,

Dear Daniel, What an suprise. I thought that you are 100%
Kantian. Ie ready to die for the 'absolute truth'. What is
wrong with the gravity? Some problems with your TT design?
We all, I think, have some peculiar problems with what you
call a 'cruel misstress'. We are the human kind and this means
not nesessarily the Kantian kind.

Kind regars,

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 let’s 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 it’s 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.
