Understand the Neck Angle Concept
The neck angle is the angle at which the neck of the guitar is attached to the body. It is a critical factor in determining the guitars playability, sound, and intonation. The neck angle can be adjusted to compensate for changes in the guitars construction or playing style.
Tools and Materials for Cutting Neck Angle
To cut the neck angle, you will need the following tools and materials:
- A miter saw or table saw
- A sharp saw blade
- A measuring tape or ruler
- A pencil or marking knife
- A sanding block or sandpaper
- Wood glue
- Clamps
Step-by-Step Instructions for Cutting Neck Angle
Once you have gathered the necessary tools and materials, you can begin cutting the neck angle. Here are the step-by-step instructions:
1. Measure and mark the neck angle
The first step is to measure and mark the neck angle. Use a measuring tape or ruler to measure the desired angle from the body of the guitar to the neck. Once you have measured the angle, use a pencil or marking knife to mark it on the neck.
2. Set up the miter saw or table saw
Next, you will need to set up the miter saw or table saw to cut the neck angle. If you are using a miter saw, adjust the saw blade to the desired angle. If you are using a table saw, you will need to use a miter gauge to set the angle. Once the saw is set up, position the neck on the saw table and secure it with clamps.
3. Cut the neck angle
With the neck secured in place, you can begin cutting the neck angle. Slowly and carefully feed the neck through the saw blade, keeping the saw blade perpendicular to the neck. Once the cut is complete, remove the neck from the saw and inspect the cut. The cut should be clean and precise.
4. Sand the neck angle
Once the neck angle is cut, you will need to sand it to smooth out any rough edges. Use a sanding block or sandpaper to sand the neck angle until it is smooth and free of splinters.
5. Glue the neck to the body
Once the neck angle is sanded, you can glue the neck to the body. Apply a thin layer of wood glue to the neck and body, and then clamp the neck to the body. Allow the glue to dry completely before removing the clamps.
6. Check the intonation
Once the glue is dry, you can check the intonation of the guitar. Intonation is the adjustment of the string length to ensure that the notes played on the guitar are in tune with the open strings. To check the intonation, use a tuner to tune the guitar. Then, play each note on the guitar and compare it to the open string. If the notes are not in tune, you will need to adjust the intonation of the guitar.
Adjust the Truss Rod
The truss rod is a metal rod that runs through the neck of the guitar and is used to adjust the neck’s relief. Relief is the amount of curvature in the neck, and it can affect the playability of the guitar. If the relief is too great, the strings will be too high off the fretboard, making it difficult to play. If the relief is too little, the strings will be too close to the fretboard, causing them to buzz when played.
To adjust the truss rod, you will need a truss rod wrench. The type of wrench you need will depend on the type of truss rod your guitar has. Once you have the correct wrench, follow these steps:
1. Locate the truss rod nut. It is usually located at the headstock of the guitar, near the nut.
2. Insert the wrench into the truss rod nut and turn it clockwise to tighten the truss rod. This will decrease the relief in the neck.
3. Turn the wrench counterclockwise to loosen the truss rod. This will increase the relief in the neck.
4. Tighten or loosen the truss rod in small increments, making sure to check the relief of the neck after each adjustment. It may take a few adjustments to get the relief just right.
Here is a table summarizing the steps for adjusting the truss rod:
| Step | Action |
|---|---|
| 1 | Locate the truss rod nut. |
| 2 | Insert the wrench into the truss rod nut and turn it clockwise to tighten the truss rod. |
| 3 | Turn the wrench counterclockwise to loosen the truss rod. |
| 4 | Tighten or loosen the truss rod in small increments, making sure to check the relief of the neck after each adjustment. |
Shimming the Neck Pocket
In some cases, the neck pocket may not fit the neck perfectly. This can be due to variations in the wood or the way the neck was cut. Shimming the neck pocket can help to correct this issue and ensure that the neck is properly aligned with the body.
To shim the neck pocket, you will need to cut a piece of thin material, such as wood or plastic, to fit the space between the neck and the pocket. The shim should be slightly wider than the neck and long enough to extend the full length of the pocket.
Once you have cut the shim, place it in the neck pocket and align the neck with the body. The shim should help to fill any gaps between the neck and the pocket and ensure that the neck is properly seated.
5. Gluing the Neck in Place
Once you are satisfied with the fit of the neck, you can glue it in place. Apply a thin layer of wood glue to the bottom of the neck and to the sides of the neck pocket. Carefully insert the neck into the pocket and align it with the body. Use clamps to hold the neck in place while the glue dries.
| Tip: |

| Use a damp cloth to wipe away any excess glue that squeezes out during the gluing process. This will help to prevent the glue from drying on the surface of the guitar and making it difficult to remove. |
Resetting the Neck
Resetting the neck is a necessary step when the neck angle is incorrect. This can be due to a number of factors, including a warped neck, a loose or damaged neck joint, or a change in the string tension. To reset the neck, you will need to remove the strings, loosen the neck bolts, and then carefully adjust the neck until it is at the correct angle. Once the neck is in place, you can tighten the bolts and re-string the guitar.
Step 1: Remove the Strings
Before you can reset the neck, you will need to remove the strings. This will give you more room to work and will prevent the strings from getting damaged.
Step 2: Loosen the Neck Bolts
Once the strings are removed, you can loosen the neck bolts. These bolts are located at the base of the neck, where it meets the body of the guitar. Use a Phillips head screwdriver to loosen the bolts, but do not remove them completely.
Step 3: Adjust the Neck Angle
With the neck bolts loosened, you can now adjust the neck angle. To do this, carefully tilt the neck back and forth until it is at the correct angle. The correct angle will vary depending on the guitar, but it is generally around 5 degrees. You can use a neck angle gauge to help you set the correct angle.
Some instruments have a bolt that goes through the body at the base of the neck, and is called a truss rod. You can adjust the neck angle by turning this bolt, which causes the neck to tilt back and forth.
If you are unsure how to adjust the neck angle, it is best to take the guitar to a qualified luthier.
Step 4: Tighten the Neck Bolts
Once the neck is at the correct angle, you can tighten the neck bolts. Do not over-tighten the bolts, as this can damage the neck.
Step 5: Re-String the Guitar
Once the neck is reset, you can re-string the guitar. Be sure to tune the guitar to the correct pitch before playing.
Step 6: Check the Neck Angle
After you have re-strung the guitar, it is important to check the neck angle once more. To do this, play the guitar and listen for any buzzing or fretting out. If you hear any buzzing, it means that the neck angle is too high. If you hear any fretting out, it means that the neck angle is too low. Adjust the neck angle as necessary until the guitar plays cleanly.
