Vintage DD turntables. Are we living dangerously?

Just to add a bit of info to the reversal discussion. My platter (actually two layers: the bottom is a Merrell lead sheet, spray adhesive attached to a thick Acromat-by-Funk hard foam mat) plus the lightest TTWeights perimeter ring and the Michell delrin center press all add up to 3 pounds 1.5 ounces. This is just a bit more than three times the original mat which weighs in at 15.6 ounces.

Needless to say, my platter doesn't reverse on stop, nor does it stop. But I see no deterioration from using a substantial bit of weight on top. I have used the combo for quite some time.

I've been knocking around the idea of getting a ceramic mat for the victor. I was concerned about its weight: 3lbs. Your report, Aigenga, is helpful to me; so, thanks.

How do you find the perimeter ring? Are there any negative effects?

I wonder how a perimeter ring could fit. The lip of the platter does not rise much above the surround. It looks cool that way but not very accommodating for a perimeter ring weight. Aigenga, Can you post a photo? Thanks.

I pretty near finished up my mods to the QL10 plinth last night. So, at last, I may actually hear a TT101 as Victor intended it, with a Victor UA 9-inch tonearm in the QL10 plinth. I will try to post a photo of the whole enchilada.

I also made, or had a machinist make, two extra alu armboards probably to be used for FR64S, Grace G714 (the wood version), or Dynavector DV501.

Here are some photos - first without the ring, showing that the achromat is thick and allows for the ring: Without Record

Here it is with the Jelco 750L (12")and a Zu/Soundsmith/Denon 103 playing a tune: From the top

And here you can see it playing from the side: From the side

The ring is only about a pound but in conjunction with the center press it is good for slightly warped records and it all sounds very fine. A 1/4" deeper ring could fit as well, the limiting factor is the speed selection buttons.

Thanks, Gary. So, basically because your mat is thicker than OEM, the peripheral ring works fine. I looked at your other photos, too. Under the platter I see first what looks like a EMI shield, a brushed silver metallic looking insert that covers everything. What is it made of? Then in some other photos, the brushed silver covering is not present, but instead the parts underneath appear wrapped in some black quilted looking material. What's that?

I have a shield between motor and platter on my L07D. Had not considered doing it also for the TT101, but I suppose it makes as much sense.
