yamaha butt flange repair

[William R. Monroe]

Maybe I wasn't clear, or maybe I'm obtuse.

How would sanding the outside of the new flanges, creating clearance from one flange to the next effect the ability (or stability) of the butt plate/pin connection??

Regards,
William R. Monroe

  Thanks Bill, I was thinking along those lines, but some of the set screws on some butts don't seem to be holding the hammer butt secure. it can be moved side to side, and will start to wooble in a short time I would think.

    richard,

    do you have a sander?

    put it to good use.  i recently did the same job, had the same trouble.

    just sand down the sides of the flanges a bit.  doesn't take much.

    best,

      Hi Listers,
      I need some advice on a Yamaha hammer butt flange replacement I just did.
      Many of the original flanges in the upper treble were so closely fitted I had to pry them loose from the rail.
      No space between. 
      Also, the hammer butt would not line up as it had been when the set screw on the plate was tightened. It tweaked them off to the side, and they just didn't feel as secure. They are not spaced to the strings properly now, and it is going to be a problem.
      I used flanges from Pianotec, pins are the same size as originals.
      The reason for the job was the silk cords being broken.
      I could use some help...
