The problem is that there is no jack flange, but the center pin goes through a hole in the wippen "proper", so I hesitate to find a replaceme= nt instead of fixing it, since this is not very common in pianos around her= e. It´s been glued before, but it broke again.  However I don´t th= ink it was glued well enough so I´d like to try it myself (the pieces fit pretty = well together) What interesting methods might be hidden there inside your brains? Wasn´t it Susan Kline that had something involving two types of glue. Could you explain thoroughly which glues ya´ll have in mind, seeing as= trademarks are variable? </BLOCKQUOTE> It's not clear in your post just how the wippen is broken. &= nbsp;I'm thinking that the piece with the hole in it for the center pin = is split.  You could use either slow setting CA glue or Epoxy. &nbs= p;If you place a small center pin in the hole while you have glued and c= lamped the piece together, when the glue is cured, you can remove that c= enter pin and have a nice, tight hole for the new one.  You would s= and or trim off any excess glue residue and if your hole is a bit too sm= all, you can ream it to a size that will work. The idea of using 2 glues is this:  CA glue sets slowly unless you = use a catalyst/accelerator.  The usual accelerator is a toxic solve= nt called 1-1-1 Triclorethylene.  It has a pungent odor and many pe= ople say that continuous exposure to it may cause serious health problem= s in the future.  On top of that, it can cause the CA glue to cure = so quickly that it's strength as a bonding material is weakened.  I= ndeed, it "fries" and bubbles up and can end up being soft and fluffy li= ke Styrofoam when cured rather than turning into a hard, plastic like ma= terial. So, there are other materials which can cause the glue to cure more quic= kly.   Baking Soda is one.  Just a little moisture is another. =  White or yellow glue has both moisture and some organic material (= particularly if it is a milk based glue) that will react with the CA glu= e.  The idea is to apply the white glue to one surface and the CA g= lue to the other, then assemble and clamp quickly.  It will set wit= hin a few minutes and probably be cured in an hour or so. Finally, if this piece ends up still being a little weak, could you trad= e it with a wippen from the high treble?  Presumably, moving that w= ippen to the last or nearly last note of the piano where it would be use= d infrequently and replacing it with a stronger part would avoid any fut= ure failure.  If the wippen has a damper spoon on it, however, you'= d have to extract the spoon and drill a hole in the high treble wippen f= or it.  You could also use CA glue to secure the spoon in the new w= ippen.  Put CA glue in the hole and dip the spoon in white glue and= insert.  It will cure within minutes.
