[pianotech] Baldwin upright: bobbling hammers, poor checking

[Patrick C. Poulson]

Tom: Thanks for correcting me on the spelling and the nature of the two materials. Ig has been  while since I have had to do a Corfam replacement job, thank goodness, and the two products are associated in my mind. 
Merry Chrismas to all!

  Patrick,
     Ecsaine not Escaine , but more importantly Ecsaine is the good stuff now used to replace the dreaded corfam . Corfam in whatever color -incarnation (see recent exhaustive list discussion on this very topic) is the material that Baldwin used 30 some years ago that hardens or goos up or in general fails in its intent.

   P.S. Ecsaine is available @ Pianotek. Great for grand backcheck recovering also.

    Tom: It sounds like Baldwin us one of the leather substitutes, such as Escaine (sp?). When it hardens up, it stays hard. You can try roughenin it up, but usually one winds up replacing it after all else fails. They used this stiff on upright catchers and hammer butts, creating loud clicking and unhappy sounds from piano technicians.
