  • 1.  gluing on leather replacement for fallboard spring contact surface on older Yamahas

    Greetings,

    A recent thread about gluing on keytops mentioned that if Roo glue is used, there is no need for clamping.

    We are replacing the leather on fallboards of older Yamahas where the spring attached to a key block interfaces with it (using Ecsaine) and have pondered how best to clamp the material to this confined curved surface. We have glued one with contact cement without clamping (other than firmly pressing the material to the wood upon contact).

    Has anyone done this replacement? With Ecsaine? What glue did you use? Was it necessary to clamp? (And if so, how did you accomplish that/)

    Thanks in advance,

    Alan

    Hi Alan,

    I just did this a couple weeks ago. Much like the discussion on keytops, I found tape was all the clamping I needed to make it secure.

    I have done it a couple of times. I used Roo glue and simply taped down the side and ends with blue painters tape.
    Worked well!

    It seems the best way to "clamp" this would be to build a negative shape using a 3d printer. I assume all the Yamaha clips are the same size. This would keep the ecsaine shaped correctly.

    Simple woodworking tools can be used build a "mirror image" caul in pretty short order. But I like the idea of tape even better. Simple...effective.
