Where can you get plasticine for cheap?

[HibouProfane]

I read often about that tweak, stuffing your turntable with plasticine, but that thing is expensive! At least, in the art supplies stores... Where can I get some in bulk? Is there a cheap replacement?

Thanks!

Wait until Satanfriendly logs in. He has direct access to the cental warehouse for this stuff

Hi

It is very difficult to remove that stuff from wiring, should you need to remove it afterwards for access.

May I suggest some automotive adhesive sound deadening pads from auto aftermarket stores.

You can get sheet lead from some roofing supplies. It can be attached to the inside of the plinth with an adhesieve. If your plinth is made of MDF, you can paint it on the inside with primer. The MDF will soak up the primer and become much harder and more rigid. I do this with speaker cabinets and it works great.

I found plasticine to be poor for sound deadening, except for weight. Acrylic latex caulking or silicone is good if you were interested in lining the inside base with it. I don't think weight is a good addition to the turntable. Build a separate base, say a top board suspended by O-rings on hooks and fill its base with plasticine. Weight will only lower the turntable's resonant frequency. Plasticine changes its shape when disturbed, which is bad for sound.

The air inside the turntable's base also has a big effect on the turntable's atmosphere. A little air cell foam on the stylus knob will add open space "de-squashing" the sound.

Some high end turntable manufacturers lined the bottom of the platter with bittumen rubber, which is similar to tar.

Others have built bases filled with lead shot. I am considering pennies layered on top of the masses of plasticine I already purchsed.

The best reults I found came from either lining the bottom of the platter with acrylic latex caulking, or gluing a layer of burlap on the bottom of the platter if space permits. But you don't want too much weight or balance upset.

If you want sound deadening you can use what Wharfedale used on its most expensive speakers:

A sandwich of two MDF panels filled inside with sand.

You can get the sand from the beach. Or there is a company that sells audiophile sand at $1000/kg. Stereophile said it gives better staging, pacing, imaging, and speed.
