Subject: String for Tri-Chord Dampers David S. said: What materials are good (or not good) for use to space toes (feet?) of tri-cord damper felt?" David Skolnik David, I prefer plain old cotton string. It's beginning to be difficult to find, but it seems to attach itself to the wool and stay where you put it.<G> Best Regards, Joe Garrett, RPT, Try a knitting supply store. A small skein of wool yarn will last you for about 300 years...comes in a variety of gauges and shades of white and not expensive. You can "unwrap" the plies to get a custom gauge. Do you increase the depth of cut between the wedges of the felt? This can improve the efficiency of the damper and sometimes eliminate the need for the cord. Paul C
