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

This was covered in detail on the Copernican thread.

I remember something about that. If the devices (such as the arm pod or the base of the platter system) use isomerics or the like between them and the plinth that **will** result in coloration. If carefully hard-coupled to the plinth the coloration is reduced. But using an arm pod is problematic as its likely that it will not be perfectly rigid and dead as the application requires.

Nikola - re your magnets question.
to best understand the French Connection and answer your question well. There is a brand new for 2020 AudioGon La Platine thread at this link.  

https://forum.audiogon.com/discussions/2020-update-jc-verdier-la-platine

I believe you will find your answers. But if you still have questions, prefer you ask them there to keep the pertinent information centralized.

This thread is about armboards and armpods. La Platine has a solid Aluminum Block Pillar that pivots. It is bolted to the top of the Plinth using serious bolts.

I will let @halcro  (Henry) address any comments questions relating to his system.

Not sure what question or answer you are referring to, or if it was even directed to me. I was replying solely to Nikola’s post.
I will say however.

Blessed is the Audiophile that finds Audio Nirvana on a budget.

Kind of like you and your Walkman that you discuss here frequently. A shining excellent example for everyone to follow.

Slowly, inevitably, this thread is backsliding into the old argument that was the central topic in the Copernican thread.  I felt that over time (and months of haggling), Halcro's approach actually began to look like an idea I could like, so that eventually there was very little to argue about. And I went off on my rigid way with my tonearm pivot firmly connected to my bearing.  It's easier for walking around.

Halcro,
My TT is a labor of love. I designed, machined, & built it myself over a couple year period.

• The platter is 4" thick solid 6061 aluminum (powder coated) with a 1/4 inch of delrin bolted directly on top.
• The plinth is 2" thick, also 6061 but dampened with soundcoat material from parts connexion.
• The bearing is a little complicated and I’m not going to get into specifics, but the thrust portion & the sidewall portion are separated. Both are attached to the platter with as little interface as safely possible. It is made of aluminum with a very thin hard coat material in the "wear" sections. It is absolutely smooth without noise or "vibrations".
• Tonearm tower (or pod) is made of aluminum, brass, ceramic, & delrin. I have it set up in a tripod manner for rigidity.
• Flywheel is also powder coated 6061 aluminum as is the motor cover. The motor itself is a Hurst.
• The record clamp is delrin, anodized aluminum, & acrylic stuffed with quartz powder.
• I purchased the tonearm from ViRa (12" version)

Although I’m sure there is better, it really does sound great. At some point I’ll dampen the platter with brass or lead-shot type materials, & probably do the same to the plinth & flywheel.

Sorry, no current pictures on-line chakster.
