    So, I noticed a crack in the headstock of my rebuild project. I'm looking for some advice on how best to address it. Thin CA glue? I don't really want to try to pry the crack open further as it seems to go with the grain and I might snap off the whole chunk. Thanks!

    Anybody out there?
     
  3. Really thin CA glue is what I would probably try. I don`t have that much experience at repairing headstock cracks, so I was hoping somebody else would chime in.

  4. Wedge it open a little. CA glue in then clamp it shut and wipe off the excess glue. Done! :)

    Thanks to RBS and the Reverend. I'll try the CA glue.

    Probably won't even have to pry it open. Stick a toothpick sliver in the screw hole then re-introduce the screw. There's a good chance that will create enough of a gap to wick in some thin CA. Remove the screw and fissure will close. Add a clamp and you're good to go.

    Looking forward to seeing the results...IOW, take a couple addt'l pics as the project progresses. Just about every non-traumatic headstock crack I've seen emanates from one of the anchor screw holes.

    Good to know. I do plan on more pics as things progress. I have a lot of sanding to do, since I made many small dings and dents as I was scraping off the sealer coat. I don't think I'll ever get all of them out. The bass is alder chunks glued together with (likely) a thin ash veneer over all, so I can't sand too heavily. Stay tuned for further developments!

    Found this video while doing some research for my own refinish job. looks to have the same crack as yours.


    from around 7:45ish.

    Fixed it with some wood glue and a clamp. No need to pry it open or anything.

    Sorry it took so long to respond - I just now found this post! I will have to try just what this fellow did. I had decided to not try to pry the crack open - I didn't want to snap the whole thing off. This approach seems reasonable/viable. Of course, now I have the bass just about finished, so I'll have to rework the finish on the neck - no big deal. Here's what the crack looks like now - still there, just harder to see:

    Just check it occasionally...if it remains stable, don't mess with it.

    FWIW, dilute TiteBond is often preferred over and above CA for these projects.

    Good show!

    Great idea! I really need to know that it has seeped into the crack, so dilution will help a lot. Thanks.

    Yeah, check the TiteBond website for specifics on recommended dilution when wicking. I should have mentioned this option earlier. I use the thin CA for "dusting"/back-filling fingerboard cracks on rosewood, wenge, etc.
