How to cut sorbothane?


I recently read a glowing review of Herbie's Big Fat Discs, which are 5/16" thick by 1 5/16" diameter sorbothane discs. So, I did some research and I found a huge variety of sorbothane sheets available at McMaster-Carr. I bought a 12"x12" by 1/4" sheet of 40 durometer sorbothane for $29.

Does anyone have a clever and easy method for cutting discs out of this sheet other than scissors? I was thinking of a sharpened cookie cutter type thing as a tool which could be hammered down on the sorbothane, effectively cuttting a disc...

BTW, I can get 8 discs out of this $29 12"x12" sheet (with useful scrap left over), and 8 Herbie's Big Fat Discs would cost just under $90.

i would think that it would work there. i have read that many folks tweak their VRs with some form of isolation btwn the cabinets.
I plan to put them between the speaker modules of my VR4 loudspeakers
Speaking of which, Audio Physics Medea had a sheet covering the whole surface b/ween the two modules. You may wish to try that before going into further cutting?
Tvad,

Your welcome. I didn't mean to dis anyones' product. It is just a matter of playing with formulations and doing the testing to prove effectiveness. The testing can be set up up prove anything (sound audiophilish?). One isolation products site compares the product results against various common rubber compounds. Guess what has a ton of rebound (relatively speaking), common rubber compounds. When modified they would be less so.

Point is - your getting at least 95% of the isolation benefit buying and cutting the sheet for 50% of the cost. Yeh, that works. That's what I want in my gear and that is why I read this forum.

And I still am a wanna-be audiophool. I went to my local dealer today and they just started carrying McIntosh. The first question out of my mouth was how do those 501's sound with Magnepan 3.6s'. I am going back when the 3.6's are in place!

God help us.

Tvad, I know you know this but just in case..........

Sorbothane can destroy furniture finishes. Unfortunately I can prove it! :-(

Best to put some waxed paper between the wood and the sorbothane.
Thanks for the tip, Newbee. I did not know that. It won't be an issue on the loudspeakers, but it would be an issue if I tried it on a component.
