AudioDesk CD Lathe replacement drive belt

I found a replacement belt at is a little thicker, 3/16", but it works fine. All 'O' rings have a designation that describes diameter and cross section. This one is designated; AS568A-353, Buna-N rubber. Price is $5.24 for a pack of FIVE + shipping. My shipping was $4.25....a total bargain...enough belts to last a sure to clean the motor drive pulley with some alcohol on a cotton square before installing the new belt....I've used it for about 2 dozen CD cuttings, and so far so good...
McMaster-Carr is an EXCELLENT source.

I found all my hard-to-find items there, you name it, chances are they have it.
