David, I buy 4 inch thick and dense mattress foam in sheets at Jo-Ann Fabrics or similar places to back some of my customer's pianos. Use an electric carving knife (like what you carve turkey with, only don't use it on the turkey afterwards), spray it with PAM or a silicone spray, and the blade will cut through the foam real easy for custom sizing. If you're trying to muffle a Disklavier, or similar playing piano, I also suggest and install the felt mute rail systems. My customers notice an immediate and most appreciated difference after an install job.

Do they work? David Love www.davidlovepianos.com -------------- next part -------------- An HTML attachment was scrubbed...
