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?”

Let the saga continue. Sail on, oh ships of Lenco!

Ok, I'll attach it to the top of the plate. Thanks again - and for the revised notes as well. Chuck
Ohhhhh… that Red Green :) Sounds humorous.

As to being down south too long - I gist bought me a steel geetar. No kidding, a '71 Emmons "fatback" out of the local Pennysaver - yeee haar! Sort of analogous to an early telecaster in terms of sound and desirability (among steel players).

Mario your offer for a slice of that thar mu metal is intriguing, please contact me.

Anyone out there have any time on their hands to build a quick plinth? I need a 3.5 inch thick plinth with as little wood taken away as possible for a Lenco L70 Deck. Super simple - alternating layers of half inch baltic birch ply and half inch layers of mdf. I need it cut, glued and squared off - I'll take care of the rest of the finishing - I just don't ahve any access to big tools right now. Send me an email if you are interested. I'm dying to get on with my next table...
If anyone wants mumetal to shield their platter as per Mario's approach, I just ordered some and will have about 4 sets of sheets that I will sell you for my cost. The kit cost $140, so each set would be about $30 (round #, including postage). If you've got the same hum I do, this is how Mario got rid of it. Email me if you're interested.
I have finally done it: I have made the Garrard 301 (grease-bearing) the equal of the Mighty Glass-Reinforced Direct Coupled Giant Lenco!! More than once I was ready to throw in the towel and either declare defeat, or actually try a low-mass approach in the thought that perhaps the Metaphysicians (who said high-mass destroyed Garrard-PRaT and that birch-ply was the only material for Garrards) were right!!

But logically, what works for the Lencos should work for the Garrards, as what more than anything made the Lencos (and other idler-wheel drives) Supreme (in a world of ball-less belt-drives and antiseptic DDs) was de facto, in practice, actually playing a record, speed stability. High mass further improves speed stability by nailing the Lenco to the planet (and the higher the mass the bigger the nails), and also, via Direct Coupling, by reducing the background noise to an empty inky blackness. PRaT, which is Pace, Rhythm and Timing, and gestalt (all of the musicams coming across as One, as they should, rather than the vivisection practiced by many belt-drives), are all a function of speed stability. If the platter revolves at a precise and perfect 33.33 RPM while playing the record, then the PRaT and gestalt should also be perfect (assuming a perfect tonearm and cartridge in this respect and so on...). High mass storing energy and releasing it over time to damage timing was a myth put forward by the belt-drive camp to explain why high-mass BELT-DRIVES were often poor at PRaT. The real reason was that high-mass belt-drives have high-mass platters, and high-mass platters cause the belts, which always react, to react slower due to momentum, at a lower frequency, where timing resides (1-2-3-4; 1-t-t-t-two-3-4...).

So given all this, then the Garrard should have responded in the same way to the same recipe as the Lenco (even to the extent of sounding incredible with a birch-ply/MDF CLD recipe, which I still find to be the most neutral recipe, truthful, dynamic and extended at both frequency extremes, if not romantic like Amazonian Kerfafala-wood, or African Gnu-lumber), and finally, it did. It is now, as well as the Lenco, a Destroyer Of Worlds. I learned in the process that the Garrard HATES rubber mats (in fact, rubber anywhere at all), and responds incredibly well to Spotmats (which the Lenco hates). Different design and metals in the two platters, as well as different main bearings, and pretty well everything else, excepting the idler-wheel systems they share (and even so with differences) explain their different reactions to different mats.

Are there sonic differences between the two? It's hard to say, but if pressed at this early stage I would say the Garrard sounds BIGGER, like a widescreen cinema, as in everything is processed through a fish-eye lens to bring the midrange forward. But in addition to this, the soundstage seems bigger too, with shortened depth next to the Lenco, which in its turn is more lazer-focused and precise and perhaps a wee bit less dramatic, though this depends on the recording I think (some types of/recordings of bass come across with more impact via the Lenco, others via the Garrard). But this could be the mats, or something else. More comparisons in the months ahead, hopefully I will be able to do a comparison of same tonearm/cartridge into same phono stage to nail things down. But in the meantime, I am happy to report the Garrard will be sharing playing time with the Lenco in my system, and I couldn't be more pleased, especially as it was the humble Garrard SP-25 which convinced me long ago that the idler-wheel system was quite simply the superior system, and once I discovered that there was such a thing as a bigger Garrard, and most especially the fabulous Beasts the Garrards 301 and 401, I began to dream of finding one and owning one, but one never came up back then, and instead I found a Lenco. Idler-Wheels rule!!!

So tonight I am once again captured by my stereo system which won't let me go, even to the extent that Kraftwerk held me rivetted to the seat, breathless, waiting for the next electronic flourish to slam across the soundstage against a pulsating and DEEP electronic bass foundation. Viva la Idler-Wheel!!
