All record weights the same ?

I'm not kidding I used a bowl and turned it upside down and added another bowl on top of that. I started about 200 grams of lead weights.
I kept adding until I got happy.. My Thorens and Russcos like it pretty heavy.

Once you get what you like. look for that weight..Total, bowls in all..

Regards

A good record weight is 180 grams.

Is 6oz heavy enough to hold down a slightly warped vinyl.

 Been using half a roll of solder wire as weight. 
  Will try the 6.3 oz one and see how it does.....

thanks

-Some of them are heavy like Micro Seiki ST-10 (900g), this is rare version for Audio Union (made by Micro).

-Some are optimal like Noritake (500g).

-There is something in the middle (between heavy and light) and in my opinion this is the best, it’s not just weight, it’s a clamp....... Look at this.

All of them are harmless for Technics! Replace your rubber mat with something like SAEC SS-300 and choose the weight you want. nice upgrade for Technics.

No they are not the same, shape is important (rounded the better), material is important (not ringing), weight is important (enough to hold firmly record down and not causing excess stress on some bearings). You may find that a threaded clamp would work better since you can adjust the downward force.

I can't quite read the brand name of my record clamp and the name I think is there, Belex, doesn't google up, But the device is lightweight and easily twist clamps to the spindle by compressing a rubber disc within. Yeah, it doesn't do much for edge warps, and if the LP has assumed a cone shape it'll only flatten it out when the cone is facing downward. I also have to support the bottom of my Sota's platter with one hand as I clamp the clamp down. But yeah, as far as I'm concerned it cleans up fidelity all around. Better imaging. Better transients. Less distortion. Better bass.

Dear @arcticdeth : For you OP what you really need is a reflex clamp as the Basis :

Dead weigth can't make that job and was what used in the old times till reflex clamps appeared.

Regards and enjoy the MUSIC NOT DISTORTIONS,

A spindle weight is one thing but a periphery ring is what will really help with eliminating warps.  I don't know if one will work with the 1200 (check platter clearance).  Mine were manufactured by TT Weights 

My clamp is 224 g. Designed for the table 
There is that.

The same bowl that oldhvymec used to cut his hair with .... remember hair?  😄 Anyone with extensive Russo turntable experience I'd trust.

This record weight is about 900g and perfect for any Direct Drive turntable including Technics. Designed and made in Japan by Micro Seiki in the 70’s. Classics! They made at least two versions of this (slightly different weight and thickness). 

In my opinion most of the modern record weights are so ugly that I don’t want them even near my turntable.

Picked up a 6.3 gr weight.
   Looks ok. 13$. It’s all I need, most of my warped or slightly warped records were flattened in my oven between 2 pieces of glass.

 Works great. 
 Thank you @millrcarbon.

<<<<<<<<<<<<<<<<<<<<<>>>>>>>>>>>>>>>>>>>>>>>>
Long live the bowl.

I do cut my own hair, I really do.. I part what's left down the middle, tape back to front with blue painters tape, cut to that margin with sharp scissors, and # whatever with a beard trimmer after that.
Summer time BUZZ. 40 plus years. :-)

My weight is 475 grams on my Russcos with a 400 gram increase from ADDING silicone on the bottom of the platter.
240 on the Thoren TD124s MK1 (magnetic platers), PLUS the 375 grams for the top added aluminum plate. That's 615 total.  360 grams with aluminum platters on the MKIIs.

Put the cats food bowl on the ol Russco and give it a bump LOL the cat jumps on the platter with the bowl.. Around they go. Just a bump. LOL go around for 6-8 revs.. Silly as$ cat. An occasional "MEOW"

Respect..

Chak, are you sure it’s good advice to say categorically that 900g, about two pounds, is ok for any DD turntable? Especially when MS made it for their belt driven high end tables? I agree with Raul that a screw on or clamp type is to be preferred usually, but a mid weighted weight may tame some resonances. I use the SOTA reflex clamp or the weight made by kenwood for the LO7D, which weighs I’m guessing 250 to 350g. Each turntable and each type of turntable may sound best with different methods for fixing the record in place, so in my opinion one needs to experiment, and choose for one’s self.

Dear @arcticdeth : "  WHATS A GOOD descent record weight that will hold down the LP..."

I don't know what advantage could you have through those 6.3grs. but I can see you are satisfied, good.

R.

"Picked up a 6.3 gr weight."

Assume you meant 6.3 ounces (which is approx. what I use on a vintage Thorens TD125II).

The lighter (as far as it works) the better, IMO.

My somewhat DIY weight is symmetrical and uniformly balanced.

@dekay 

 yes, must be 6.3 oz.  180 or so grams as recommended by @millercarbon. 
 She is a  30+ year old SL-1200 mkii. 
 Should be just fine, if not, I’ll continue to use my half roll of soldering wire on the spool. 
 Thank you everyone. 

I think Raul and Lewn are on the right track. Any additional mass on a bearing is going to accelerate bearing wear. Just a fact of life. A plain record weight no matter how heavy it is can only press the label against the platter. A proper reflex clamp as used by SME, Kuzma and Sota flexes the record into the platter without the need for unnecessary mass. These are second only to vacuum clamping. Plain record weights are just shy of being worthless and heavy ones will ruin your bearing prematurely. 

Received the weight in the mail yesterday.    Seems fine. Will use this weekend and see how she works. 
     Since there is no contact as it’s the reverse magnetic sl1200ii direct drive, I should not worry much about the extra 6.3 ounces on the platter???

Chak, are you sure it’s good advice to say categorically that 900g, about two pounds, is ok for any DD turntable? Especially when MS made it for their belt driven high end tables?

 
Why do you thing they made it for Belt Drive turntables ? Micro made Direct Drive turntables too. 

900g is OK for all Direct Drive turntables, probably 500g is more comfortable for the user, but it's irrelevant for the motor/bearings. 

I agree with Raul that a screw on or clamp type is to be preferred usually, but a mid weighted weight may tame some resonances.

Micro ST-20 is lightweight and it's a clamp, not just weight like cheaper ST-10. 

I use the SOTA reflex clamp or the weight made by kenwood for the LO7D, which weighs I’m guessing 250 to 350g. 

I tried many (same weight) and in my opinion they are too light imo. 

I would just say to a neophyte, approach a 900g record weight with caution, regardless of the drive system, especially if your turntable has a lightweight platter, which suggests the bearing may have been designed with low platter mass in mind. That’s a long sentence with a lot of commas. Sorry.

"...A good record weight is 180 grams..."

I see what you did there. What's a record weight weigh? 

450-500 grams is enough to damp vibrations and light enough to not stress the motor, this is around 1lbs.
