How to Fix Impossible Neck Breaks on Guitar
How to fix broken necks on guitar
Do you need to know how to fix a broken guitar neck? Are you are a parent of small, busy and accident-prone children? Do your children have music lessons or play guitar in school?
You may not have the money to buy a new guitar for little Johnny B Goode when he knocks his guitar flying across the room and the neck sheers off. You might not feel inclined to "reward him" for breaking his guitar either. Music shops will almost certainly tell you it is not worth fixing, but a broken guitar neck can be easily mended at home. You only need a few household objects and some determination. This page teaches you how to fix the impossible broken guitar necks!
After years of teaching guitar and seeing distraught children give up playing guitar after these unfortunate accidents, I got my head together with Colin, who is always very practical, and we came up with an emergency method that actually does work for cheap kid's guitars and is simple enough even for me.
If repairing the neck gives you another six months before you have to buy that new guitar then it is worth doing. You can maybe save the new guitar as a Christmas or birthday surprise and meanwhile the old guitar can take the battering of the journey to and from school. Chances are with this method it will last a long, long time.
How to fix that broken guitar neck
What you need to fix the impossible break
To be clear, we are talking about a child's guitar that has been beheaded at the shoulders! This one fell off a wall hanger. This is one reason I do not recommend you hang your guitar on a wall! I have also fixed several guitars with broken headstocks, but that is a different game and not one I recommend you take on without proper clamps and the knowledge that it is touch and go anyway! This is an emergency repair on a beginner instrument and intonation may not be exact at the 12th fret, but how many beginners play up "the dusty end" on a nylon strung acoustic? In my experience tuning discrepancy is minor in normal beginner use if you do the job properly - and this bad break remained surprisingly in tune at the 12th!
You will need:
A ball of strong string
Scrap cardboard for padding
Strong furniture or wood glue
Two screwdrivers or strong thin pieces of wood, plastic or metal.
A large G clamp and some protective pads
Damp cotton wool
A guitar broken in two at the join with the body

The Alfred Kid's Guitar Course is great for beginners and provides the complete package to get you going on the instrument.
Construction of the guitar neck to body joint
Is it fixed with dowels or simply glued?
How the neck is fixed impacts on two things, the severity of the break and the ease of fixing. What this means practically is that a dowelled neck is harder to sheer off totally and easier to fix than the cheaper non reinforced neck - but do not despair! Even if it is not dowelled it is repairable but will need a lot of care and patience to do. Realistically, if the neck breaks on a kid's nylon strung guitar, you are likely to also have a lost 12th fret, so this type of repair is not feasible for a guitar belonging to an intermediate or advanced player.
Acoustic Guitar Repair Books - Checking guitar repairs with the experts
Here is a decent set of guitar repair resources. I did my basic learning in the piano workshop of a music store. These days there are proper courses in instrument repair and manufacture that kids can go to if they want a career as a luthier, but these books are a great help to the keen DIY repairer.
First Steps to Fixing a Broken Guitar Neck
Preparing for the job, cleaning the joint and glueing it
First loosen and remove all the guitar strings. The string tension will work against the joint setting properly, so you must do this. I usually loosen the strings, remove them at the bridge, then tie loosely around the headstock. There is little point replacing the strings until you know if the guitar repair is going to be permanent! In this instance, it was an unreinforced neck too, so I wasn't sure the repair would take. If observant, you will notice the top nut is missing too - this particular student had lost the , so that had to be replaced as well. fret 13 was also long gone, but that didn't matter too much. Nut and Saddle
Cleaning up is an essential first step when fixing a Removing all loose splinters and old, deteriorated glue will ensure a better chance of success. I do not plane the area smooth though, as leaving it rough ensures a greater surface area for the glue to stick to and makes for a stronger repair. Apply glue thinly to both sides, it only has to be thin, because a lot of this glue will be squeezed from the joint when pressure is applied later. At this point, bring the two surfaces together as accurately as you can. If the guitar has dowels this will help with neck placement and keep it together, if it does not, get an assistant to hold the neck in place flat on a table while you complete the next step.

Wood Glue for your Guitar Repair - Buy strong wood glue to fix your guitar
The key to making this work is to use a decent wood glue that is easy to apply, preferably not too messy, and will set harder than the wood itself. It will have to take a LOT of pressure with the strings back on. Here is a selection of wood glues....
Making the repair permanent
How to clamp an acoustic guitar with household items
You don't own a guitar repair shop I take it? If you check out a luthier's shop you will see a myriad of amazing jigs and clamps just for the purpose of construction and repair, but experience tells me a professional neck reset is probably going to cost about 3-4 times as much as a new guitar! We take what we can get, and common or garden string is what you need here. While your assistant makes sure the neck stays fixed accurately, wind some string around the guitar, knotting it in several places as you go. I don't recommend nylon string as the breaking strain is so high you could easily crush the wood, sisal. hemp or cotton twine will have a natural elasticity that will offer some protection.
String for your guitar repair - Natural fibre is best....
You are going to use string to construct your guitar clamping device. Choose carefully, because this string will have to be tightened like a tourniquet to put pressure on the repaired joint!
Fix It or Bin It.... - What is your view?
Would you fix your kid's guitar or not?
Yes, it would give me time to save for a new one and perhaps teach him to be more responsible.
Applying a Tourniquet to your Guitar
The trade secret or fixing broken neck permanently....
The string should be loose enough to insert some card at each point the string is in contact with the wood. This is important as it will offer a little protection to the finish and the wood. The string is going to be at very high tension. How? Read on...
By itself, that string is not going to be strong enough to ensure a secure repair, what we do next is really neat. Using a screwdriver or pencil, insert between the strings and twist. Do this at the waist, where nothing touches the guitar, then secure the shaft and handle, or both ends of your pencil with some string. Tape over the string for extra security too.
Do this both sides, and you will see glue squeezing out of the joint. If you have a G clamp, secure this over the fretboard at fret 12 with the heel, pad both and tighten. Unfortunately the juice ran out of my camera, so I did not photograph this step, but if the guitar has dowels in the joint and the fretboard has a clean break it will not be vital. At this point it is a good idea to clean away any surplus glue with a damp piece of cotton wool or tissue.
Finishing the neck repair
Final steps in repairing the broken guitar neck
Leave the guitar for at least 24 hours before you remove the string clamp. Loosen the "tourniquets" first, then the string will just slide away as it has stretched. At this point you can reattach the strings loosely, glue in the topnut if it has come away. Do not tune up to concert pitch immediately, but leave the strings loosely attached and then just let the guitar alone for about a week for the glue to cure. At this point, tune up to pitch gradually over an hour or two and hopefully the repair will hold up! I have actually done this emergency repair maybe a dozen times and it has always been successful giving the parents time to save up for a new instrument.
This particular guitar was a very tricky one, but so far the repair has held up and it is not too badly out of tune and is playable to the 12th fret. It was tough because there were no dowels and there was other damage. The fretboard was also broken as you can see and I had to put a G clamp on to complete the repair and close the gap you see in this photo. So far the patient remains in a stable condition....

The G clamp just helps to keep that repair snug while the glue sets. I wouldn't attempt a repair without one actually because of the tensions involved here.
Professional Guitar Repairs and Set Ups - For great guitars!
My emergency repairs are undertaken because these repairs are very expensive (more than the cost of a kid's guitar) . I don't recommend you do this to your favorite Martin, Gibson or Baby Taylor. If you have a great guitar in need of repair, take it to a professional for a proper reset or neck replacement please!
