  • 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-

    It's been several years but I'm pretty sure I used a simple hot glue gun.  Those sticks dry very quickly with no special clamps needed necessarily.  They don't absorb into the leather much either.  There might be a better method but that worked with no problems later.   

    Good luck!

    I did several of these. I found fish glue worked very well. Good idea to rub powdered teflon into the bearing surface of the leather before gluing it in.

    Some of you may very well be in tune to the characteristics of hyde glue. I was not aware of the some of the subtle types presented. You too might get answers to your general questions by watching this whole presentation. This guy really knows his stuff. ✌🏼
