Hello All, This question which follows was faxed to me. Please respond if you have some comments that would apply. Thanks, jeannie Jeannie Grassi, RPT Assistant Editor, Piano Technicians Journal mailto:jgrassi@silverlink.net **************** "Over the years I have acquired a collection of caster cups. They are of wood, glass, composition wood, celluloid and metal (brass). How do the different materials enhance or inhibit the sound on a rug, a hardwood floor, or cement? What about spiders and rubber wheels on stage pianos? Thank you for your help and time." Helga Kasimoff Associate Member Los Angeles
