Schwander return spring loops

[Carlos Ralon]

Hii Wim,
I buy them by the 100's from Yamaha. The time saved and not having to repin over-ride the cost. Remember to cost out the job the way you want to do the job, which is not always the cheapest.  Most Yami P202 ond older consoles, as well as older Schwander actions need this job. I don't think the Schwander flanges are that available, so the string thread job must be done.

  I haven't had to do this yet, but I do have a couple of pianos that are ready to have new cords put on. I have thought about replacing the cords, but with it taking 4 - 6 hours, wouldn't it be "easier" to put on new flanges, and travel the hammers?

  Hi, Terence:
      I've done this job many times.  There are more ways than one to do this, but here's what I've been doing.  Put your action in a cradle, then:
      1) Remove the hammer rest rail.
      2) Remove the bridle straps.
      3) Most Yamaha consoles have flange plates, so you can leave the flanges on the rail.  Loosen the flange screw and remove the hammer butts/hammers.
      4) Use a thin saw blade to scrape out the silk cord from the slots in the flange.
      5) Use a 5/8" dowel and wrap your new cord (recommended "spiderwire" ) fishing line around it, then slice all the loops at once with a razor blade.  The diameter of the rod makes the loops uniform size.
      6) Use your glue of choice to secure one end of the loop to the flange slot.  Go back and glue the other side.  I've used CA gel glue, using an accelerator.  Sets up fast, but use care it doesn't gum up the flange bushing or leave buildup on the flange surface that will interfere with the butt when you reassemble it.  I've also used pvc-e glue.  
      7) Reassemble the butts/hammers, bridle tapes, rest rail.  Done.  I'd estimate 4-6 hours.
      Play some music or books-on-tape while you do a tedious, boring job.  Have fun.

          Dear List

          I am grateful in advance for whomever points me to the most efficient procedure for replacing these cord-loops in a mid-80s Yamaha console.

          Most all of the cords have failed not at the spring but at one side of the flange or the other where the cord begins its life as a loop.

          thank you

          Oh,

          take the rest of the day off!
