Removing PVA glue

Posted by ross harper (rustic luthiery) on January 19, 2011 at 6:06am in Building Secrets, Tips, Advice, Discussion

    Greetings!

  Just had to start again after warping the neck on my latest attempt and while looking at the old neck,I wondered if it's possible to separate the Jarrah fretboard(still good) from the Tasmanian Oak neck(buggered).They are joined with PVA glue,is there a solvent or something that will get rid of it? I probably should've paid more attention at Woodwork Classes at school!Thanks for any advice.

      Don,AFKM,Hermit and Ben,

      thanks for the ideas,I might just hang it up with a sign on it not to do it (cut head too thin)again! I think I'll try hide glue one of these days.Ross

      PS the replacement neck is coming along nicely.Still using PVA,though!(See last line of main reply)

    Good guesss but that chair (as is most old furnature) was likely assembled with hide glue. (That's why I now work with hide glue if I think I may ever need a joint to come apart)

    Whilst i was cleaning French polish off an old chair with methylated spirits, I found the joints and spindles started to soften enough for me to pry open and remove the old glue and gunk.

    Hope this is of some help.

    If the neck is trash anyway .... just carefully cut the fretboard from the neck leaving a thin sliver of the neck attached.

    Now just sand the remaining neck wood and pva off.

    Hi Ross, PVA is water soluble when wet however once it's set I can't think of a solvent that will soften the bond. You might try a putty knife with heat working slowly pry it apart but honestly I have my doubts. Sorry, I can't think of a silver bullet fix for you.
