I saw a less than mediocre rebuild today with a bare rail. Even with the screws tight, the flanges could be turned. How can the felt reduce impact noise with the screw transmitting the energy to the rail. I use fine emery cloth which I buy in a roll from Klingspor and cut 1/2' wide, long strips. I use double- sided tape used to affix plastic sheeting to windows; 3M makes a 1/2" wide tape for this...perfect. Once the cloth is down, sometimes continuous, I punch a few holes with an awl and install the flanges, punch a few more... The tape and cloth can be inserted under the tenor, thin brass support by bending it upwards slightly and then straightening. -- Regards, Jon Page
