crazy vinyl clamp

[dcmfan]

I was thinking Ironwood (Lignum vitae):

...widely used in water-lubricated shaft bearings for ships and hydro-electric power plants, and in the stern-tube bearings of ship propellers until the 1960s saw the introduction of sealed white metalbearings. According to the San Francisco Maritime National Park Association website, the shaft bearings on the WWII submarine USS Pampanito (SS-383) were made of this wood. The aft main shaft strut bearings for USS Nautilus (SSN-571), the world's first nuclear-powered submarine, were composed of this wood. Also, the bearings in the original 1920s turbines of the Conowingo hydroelectric plant on the lower Susquehanna River were made from lignum vitae. The shaft bearings on the horizontal turbines at the Pointe du Bois generating station in Manitoba are made from lignum vitae. Other hydroelectric plant turbine bearings, many of them still in service, were fabricated with lignum vitae and are too numerous to list here.

Ironwood is pretty amazing. What's also interesting is that there are people like me who care not a whit about imaging at all, I live for high-fidelity and enjoy the sonic trip you get from stereo sound, but where the bass player sat when he was recording after he spilled his vodka and put his ashtray on the floor doesn't really interest me. If someone wants to spend $3500 bucks for a weight to better echolocate him, more power to them.

There are quality pucks made with Panzerholz (Wood) out there on a market that cost about ten time less than the one from Clearaduio!

Thats a weight and not a clamp.

If you have some consumer deck and and really something with fixed tonearms and budget carts, you don't need this expensive of a clamp. However you need a clamp, maybe a Michell clamp would be for you. Either that or you like to have one side of the record sound different than the other side, or you like watching your tonearm going off ski jumps. You need to couple the record to the platter to tame resonance.

Clamps and felt & rubber washers, Look at the clamps that have a hollowed out area on the underside that's the type one need, not maybe, needs!!!

No record is perfectly flat, they will all have a dish to them or even warps. If the outer edge looks like it's flat, well the label area and inner grooves are most likely lifted off the platter somewhat. And if you flip that record the inner area will lay on the platter but the outer lip will be raised. The following pictorial is with a pretty bad dished record and you can see how a clamp works. When the pucker is high like a dome at the spindle you just use the clamp and it holds down the center of the record making the record flat. But when you flip sides you use a washer to force the outer edge flat, in turn the whole record is flat.

Just reading the description made my records sound better!

Just reading the description made all mine sound worse!

Was reading this thread and thinking of lignum vitae and you beat me to it. I actually have a piece on the shelf, maybe I'll make it into a record weight.
It's an endangered (or at least threatened) species now so international trade in lignum vitae is banned. The only stock you'll find is either poached or old stock.

Where do you read 'CLAMP' in my post???
Not even the one in the OP is the clamp!

(another reason to keep you on my ignore list!)

Again incorrect, the topic is record clamps as is the Clearaudio Statement Record Clamp

You then go on to say,

I corrected you as your weighing apples and oranges as being the same, sorry it doesn't work that way.

I'm not sure how that Clearaudio piece mentioned in the OP qualifies as a clamp. It looks like a weight or puck to me. How does it function mechanically as a clamp, rather than a massive weight?

 

[JP]

Ditto. I see no mention anywhere that it's a clamp in the sense that it grabs the spindle. Also, in their own marketing literature: "Clever indeed, the Clearaudio CleverClamp doesn't rely on weight to do the job." It'd seem they don't differentiate between weight and clamp - looks like they're all clamps to them, utilizing different mechanisms to accomplish the job.

 

[juno]

Their literature is confusing. It looks as if it relies on weight. It states there is a tube that fits over the spindle. But then mentions ball bearings in the wood, which I assume are not in the spindle. I don't see how it can mechanically lock in place with whatever downward pressure one chooses to apply, such as a screw down system or a spring and claw system. I think the guy who posted the binder clip has more of an actual clamp!

@4.2.7

Go and correct the OP, if you're really passionate to be a preacher of this thread! Yes, he did write the 'CLAMP' in the title, but it is so obvious that IT IS NOT A CLAMP, but only a weight, just as the one i mentioned in my post, that you take here to jump on my back all over again. It's been a while, since you were quiet for about the year, but here you go again.

 

[juno]

I would agree with Jadran.

However, the OP does not need to be corrected, as this item is.....

ADVERTISED AS A CLAMP!!!!!

"The Statement Clamp is a heavy stainless steel and Panzerholz (bulletproof wood) record clamp equipped with anti-resonance mechanical grounding. The Statement Clamp will help extract every nuance and detail from your vinyl records."

Can anyone insisting this is a clamp show how it is, in fact, a clamp? By its nature, a clamp does not need to be either "massive" or "heavy" as one would expect a weight (no pun intended) or puck.

Thanks juno! Neither I have to be corrected, but some always have that urge to preach others.

Made with real bits of Panzer. They've done study's you know? 60% of the time it works all the time ~Brian Fantana~

?? No I don't
They also call it ''High End Record Clamp''
PatheWings Fusion 380
made of Stainless Steel + DuraWings + PanzerWood®
and it is ''just'' a heavy record weight.
Clamp I bought in Germany is quite light and fragile (made of aluminum and plexiglass), but IMHO better than any heavy weight I tried. TT motors also like it a lot.
