Building high-end 'tables cheap at Home Despot II

“For those who want the moon but can't afford it or those who can afford it but like to have fun and work with their hands, I'm willing to give out a recipe for a true high-end 'table which is easy to do, and fun to make as sky's the limit on design/creativity! The cost of materials, including 'table, is roughly $200 (depending, more or less), and add to that a Rega tonearm. The results are astonishing. I'll even tell/show you how to make chipboard look like marble and fool and impress all your friends. If there's interest I'll get on with this project, if not, I'll just continue making them in my basement. The next one I make will have a Corian top and have a zebra stripe pattern! Fun! Any takers?”

Thanks Dave,

I already have. I was just making an observation that many have made before. That's all.

My whole idea with the slate layer was to add another layer to the classic, high mass, giant CLD plinth... I was picturing the slate as described by Mosin, as an infinitely finely layered cld..., but I still wanted to retain the qualities, and (in my eyes) beauty of the "Nantaisian' Lenco plinth...
I was considering what John brought up, regarding ringing... and I am seeking out a suitable damping material for the pressed steel itself for this reason.
Even if I eventually go with a solid layered slate plinth, i will still box it with oak, to maintain that classic wood plinth look.
Your debates are healthy, and raise valid questions, and useful perspective that we can all benefit from. Theory and practice are two different things... so none of us should get too emotional over any of this stuff yet... I will stick to getting emotional about the music! John, I will talk to my friend next week! Harv

Harv,

If you use the Dutch aftermarket plinth, why couldn't you just glue it down with a thin layer of J-B Weld or other good epoxy? It is flat, and I believe that the interface would be adequate to maintain all the sonic qualities without detriment. By the way, I have glued metal to slate and it bonds very well.

A gent over at Lenco Lovers did some experiments using a cement filled plinth. The results had interfering transmission in the form of rumble that had to be eliminated with further secondary layering with a softer foam layering underneath.
His take on this was that sound (in the form of unwanted transmission) either passes through or is reflected off of dense material. It doesn’t simply vanish. The alternating of dense/soft layering as in the constrained plinth allows for an overall dissipation in transmission because of a scattering of unwanted interference because of the divergent pass-thru/ reflective properties of the materials used.

Before we all rush to give exalted properties to slate as plinth material (including myself), I would submit that it has more in common with this cement plinth than the constrained “sandwich”.

Hi Mario

Not sure we can generalise with any of these 'stone' materials - there are many types of slate with differing qualities, the same can be said for: limestone (probably more so),sandstone, granites, marbles etc.

As concrete (I assume this is what is meant by cement) is made with OPC and an aggregate then is is also dependent on the qualities of said aggregate which could be any of the above materials or other e.g. lead shot. We might even get into the realms of Lime Concrete which would be different again.

Plus the LL experiment is only one sample, I would suggest that many more examples would need to be tested before one can state anything for certain.

I would also suggest that we need to dispose of the CLD 'blinkers' and accept that there may be other ways. I'm not even really sure what we are all doing with plinths actually is CLD in its true sense.
