[pianotech] broaches for flange bushing

[Don Mannino]

David,

Usually they are just dirty.  Cloth that has been lubricated gums things up, so clean with denatured alcohol or Naptha and they should work good again.

  >Hello List,

  Do the roughened areas of broaches used for flange bushing need to be sharpened periodically?

  I?m in the middle of re-pinning a set of hammer flanges and it seems some of the broaches cut better than the others.  If yes, what?s the best way to sharpen them.

  Thanks,
