1994 Guild JF30-12 Jumbo 12-String Guitar

This is a nice old JF30-12 that had succumbed to a bunch of neck joint trauma. I "reset" the neck and neckblock and reinforced the area, gave it a level/dress of the frets, fully-compensated the saddle, and set it all up for its owner with a set of extra-light 42w-9 strings. Considering how bad the joint was, I didn't want to roll the dice as he's keeping it tuned-up E-to-E standard. I've included photos of the repair process below the "glory pics."

Here are some in-process repair shots, showing my technique for repairing a "slid-forward" neckblock/fretboard extension job...

The "pinched" joint is because the neckblock is the same width, basically, as the fretboard and the "extension block" under the board is as well. This is a recipe for dryness cracks along the fretboard to "slide" the top forward with the whole neck pitching-in...

Here I've removed the binding that's crunched-in so I can get at the seams and joint.

I have two blocks under both the endblock and neckblock areas on the back. One clamp at the endblock holds the guitar in place. The other clamp on the neck is applying enough pressure to shift the neck back into its "factory original" position. From there I can start to reglue the joint area.

I got a bunch of epoxy into these seams before clamping.

These are two, new, mahogany "neckblock extenders" that I will be gluing-up to both the top and the side of the neckblock so they form a "larger neckblock" once in place. I also but them right up to the kerfing on the inside. I use epoxy to put all this in place so it fills any small gaps that may be there.

Here it is all clamped-up!
