TT mats

I have a VPI Scoutmaster TT and am wondering if any of you can recommend a matt for the platter and why?
Thanks in advance
Steve

@bdp24 Where are you getting Isodamp pricing? What you’ve posted is a nonsensical price.

Isodamp C-1002 Series 0.125" thick, 54" by linear foot is $68. That’s a lot of material. Can be ordered from the authorized distributor direct: https://www.rathbun.com/c-40-damping-isolation-materials.aspx

Michael Percy sells SD Series (what SME uses) 0.125" thick, 12" by 27" for $60. http://www.percyaudio.com/Catalog.pdf

Both sources have other thicknesses and sizes.

Oops! I was looking at the R.S. Hughes Industrial Supplier website, and misread the price sheet. The $238 amount is correct, but that's for a piece 5.4" by 4 feet, not 4 inches! If I had thought about it for a minute, it would (or should) have been obvious that Isodamp COULDN'T be priced THAT high!

The 12" by 27" piece Michael Percy sells for $60 (I'll take your word for it ;-) is enough to make two mats out of. How does one cut Isodamp into a perfect circle?

@bdp24 I would just place a record on top, trace it, then use sharp scissors.

The SD series from Percy are all adhesive backed. The strength of that adhesive is practically permanent. If you decide to try it, I recommend doing so without removing the protective film.

Thanks invictus005, but the Isodamp is not for my tables, all which have platters made either entirely of Delrin (Townshend Audio Rock), or aluminum with a top layer of Delrin (VPI). I have looked at the Isodamp for constrained layer applications, but didn't know it was available in black, as the SD-125 is. A lot of it is available in blue only.

My VPI Superscoutmaster has the aluminum platter and I use Herbie's Audio Labs Grungebuster Mat. Protects the records and sweetens the sound a bit. To clean, I remove it from platter and run it under hot water. I love mine. Looks good as well...
