Thanks for your valued advise. With all the input on this , I think I will use these knuckles and shim the gap, make sure the knuckle is perpendicular and all are uniform distance from the center pin and use high solid glue... Which raises the question; are hide glue and wood glue high solid glues?</DIV> <DIV>Thanks,</DIV> <DIV>Larry Trischetta</DIV> <DIV> </DIV> <DIV><I>-------Original Message-------</I></DIV> <DIV> </DIV> <DIV id=receivestrings> <DIV dir=ltr style="FONT-SIZE: 11pt"><I><B>From:</B></I> <A href="mailto:A440A@aol.com">A440A@aol.com</A></DIV> <DIV dir=ltr style="FONT-SIZE: 11pt"><I><B>Date:</B></I> 12/3/2006 8:03:50 AM</DIV> <DIV dir=ltr style="FONT-SIZE: 11pt"><I><B>To:</B></I> <A href="mailto:pianotech@ptg.org">pianotech@ptg.org</A></DIV> <DIV dir=ltr style="FONT-SIZE: 11pt"><I><B>Subject:</B></I> Re: Knuckle question</DIV></DIV> <DIV> </DIV> <DIV><< knuckles to install and the wood core is slightly</DIV> <DIV> </DIV> <DIV>narrower than the slot (it reaches the bottom).
