    .

    They use hide glue, but regular titebond wood glue will work.
    Key is clean out the cross fibers and tap the pieces back together while clamping like you see here.



    Router jig splines later may be a good idea as previously mentioned. You might survey how the neck turns out from the first step of getting them back together.

    again this genius guy has the solution,but what is the best glue for the job (mahagony neck)? Titebond?

    Some adhesive that sticks to carbon fiber. White and Yellow glues are for porous materials. Probably a longer setting epoxy would do the job.

    I gotta say if that was my guitar and I somehow sold it for $85 I’d be dancing a little jig.

    That Slash signature LP was a case of outrageous headstock break. I still wonder how hard the guy fell on the ground to cause such damage (one inlay popping out!).
    I've had already seen this video but watched it again with great interest: twoodfrd's videos on YT are always so satisfying to watch!

    the repair is pretty easy if you know what you're doing...
    so..the one who's dancing is me...cause I've just received a 500$ Epiphone Les Paul plustop pro in mint condition for 85$...the repair (diy) cost me 10$....ceeeeelebra-aaa-aaa-tion,come on!!

    some more picks...the glueing is the easiest part...

    which method would you prefer...transplanting carbon fibre reinforcement rods or adding wood stripes on the back of the neck?

    Save the dance for when it’s done. ;)
    Yes I admit this is neat. I would have built a solid clamping device, but maybe the simpler method is better. The only problem with dowels is that you are not reinforcing the point where the break started, that is probably the thinner part of the wood, on the back just under the trussrod channel. So after gluing is done the weak point is still there. The « splines » method takes care of this (but is much more difficult to do).

    Any wood glue would work, Titebond is standard.
    I would glue the headstock with titebond and the rods with epoxy. Be sure to use slow setting epoxy.

    Glue the head on then drill thru headstock and neck and add some thin steel rods.
    If not strip it and sell the parts.

    Cut neck off at body, route neck pocket, install 24.75 Fender neck, never deal with this problem again.

    thanks,some good considerations...the two broken parts fit together like "fingers"..so the carbon fibre rod method could really work. I'm thinking, beside the rubber band, to softly clamp it (fingerboard/neck backside),because there's some "flesh" left on the peghead "wound" (backside of the neck)

    The hardest part with the "spline" method is constructing a frame for the milling...the rest is fun

    ..It's an option,perhaps aluminium rods?

    Perhaps you could use the truss rod as a clamping anchor.
    screw something to the truss rod and some retainer to the headstock. you know, like a built-in clamp.
    I'd think the position is perfect to start the glue job and have everything aligned.

    after it's dried up and in place you can go for the method of your choice to re-inforce the joint. rod or spline.

    From an engineering perspective, the drilling/rods tech is an elegant solution. Carbon/epoxy is going to bond better than any metal rod alternative. Bond strength inside the repair is critical - if the bond between the rods and the wood starts to fail, there goes strength of repair.

    One slight mod, though. It would be good to stagger the end points of the rods, to avoid a stress riser where they both end at the same place on the neck. Any way you could figure to do that with the endpoints on the headstock would be good too; but might be difficult to put into practice.
