I've always gone with the thinnest wool punching practicable with heavy card/paper under that, trying to use a minimum of paper. I have ironed the felt before installing them before but don't put too much stock in the benefit of doing so. I'm always a little surprised and much impressed to find very thin red punchings with few, and sometimes no, paper or card punchings in a lot of newer pianos....namely Yamaha, Kawai's, etc. Paul Dempsey Marshall University Wimblees@aol.com wrote: >In a message dated 10/24/02 9:48:46 AM Central Daylight Time, >nhunt@optonline.net writes: > >> Paper does not compress, wool does. >> >> Newton >> >> > >But shouldn't you decompress wool punchings before using them? > >Wim > ------------------- Paul E.
