Gibson J-50 Broken Heel

    Hello all,

    Hoping that someone can suggest a clean way to help remove the heel of this neck from the neck block.

    This guitar came to me with the heel broken almost all the way through and wouldn’t ya know, the last little bit of the wood separated before the dovetail joint. I’ve had foam cutters in the space behind joint with some moisture to try to loosen the glue, but without the leverage from the neck, the joint has proved super stubborn.

    Any one have some magic they can suggest to get this thing out decently cleanly?

    Many thanks!

    Doc

    This tool will probably do the trick. I made mine, not that difficult.

    And possibly add more heat probes. You can add at least two more to the situation. Personally, I’d put six in since you can see exact placement. One each, at the four corners and two in the middle of the flat section (Marked barley in yellow on your pic, hope you don’t mind). Use two soldering pencils. You can use much thicker gauge wire then on the foam cutters which use 18 ga. I’d use 12ga. Works great. Martin neck joints (you probably know this and I’m being pedantic) are usually among the easier joints to pull. You can check out how I make them if your interested: https://dev.loothgroup.com/post-type-videos/neck-removal-with-soldering-pencil-version-3/

    Forgot to add that you can add just a touch of water with dropper to holes. This will displace air in cavities and help soften glue, but not enough to pose risk to finish by seepage. More holes and heat better than tearing out heel causing more damage. Good luck!
