VPI Super Platter

From what I read here and at AA it appears the general consensus is that the Super Platter is a fairly significant upgrade from the all acrylic platters on the newer Scoutmaster and Aries turntables. However, I have an older Aries 1 with a fairly heavy platter that resembles in appearance, the Super Platter. Any Aries 1 owners know the one I am talking about? Would the Super Platter be as significant an upgrade to this platter as it is to the acrylic ones? Also, does the inverted bearing that comes with the Super Platter represent a significant improvement over the bearing I already have. My Aries is about 6 years old and has the JMW 10 tonearm. I also have the SDS.

Boca Bearing on-line has SiC balls. I suggest polishing the inside of the non-inverted bearing cup with compound and a pointed felt dremel bit until the ball rolls smoothly in the cup. For reassembly, retain the ball in the cup using a few drops of oil between the ball & the cup. Get the oil change and the correct oil level done first before switching to a SiC ball. The ceramic ball is nonmagnetic. During subsequent service it will have to be retreived from the well with a small automotive grabber or by turning the well upside down. But I wouldn't expect a need for much servicing as the ceramic balls are harder & smoother than steel.

Sorry, I mean Si3N4, not SiC ball bearing.

Mark,
It was one of the MK4 upgrades, maybe the first, for the HW19. The Mk4 used whatever TNT platter was in use at the time and then later, the all acrylic black platter from the Aires Black Knight. The lead/delrin platter is 1 1/2 inches thick, all black, has cork on the bottom. The top is slightly rounded from the playing surface to the side. Weighs about 16 pounds.

You can get the Silicon-Nitride ball from McMaster-Carr. The VPI bearings use 1/4 inch, about $8 for a two-pack.

Hope this helps....

Hello folks, Thanks again all for this good, valuable information.

Yes, my HW-19 uses the Lead Ring Black Acrylic Platter (which I bought right here usedfrom a great fellow agoner JDOLGIN), with Cork Underside, exact weight came to 18lbs, was stated to be the Mk-IV Platter, but does appear like you say, some iteration of one of the TNT Platters. Lovely Platter BTW.

I was under the assumption that VPI perhaps used a Tungsten Ball on the bottom of the Bearing Shaft, but maybe my assumptions were wrong about this?

Next time I service-lube my Bearing, I will double check the size with Dial Caliper, and order these bearings from your advised sources. Thanks again all, Mark

I looked at the bottom of my MK III bearing and the ball looks pressed into the metal. No periphery ring holding it in and no way (that I can see) of prying it out without damaging something. Is there a trick to getting it out?

Also, the original steel ball looks smaller than the 1/4" Silicon Nitrides that I ordered. I doubt that they are the same size. Or is the MK III just a very different animal from the above?
