The Basics of Cutting Record Vinyl
Get to know your equipment.
Record cutting is a unique process that involves a handful of important pieces of equipment. Here’s a rundown of the key components:
- Turntable: The turntable provides the rotating motion that the vinyl blank spins on during cutting.
- Cutting head: The cutting head is the device that physically cuts the grooves into the vinyl blank. It is made up of a stylus, which is a sharp, diamond-tipped needle, and a transducer, which converts the electrical signal from the audio source into mechanical vibrations that cause the stylus to move.
- Cutting lathe: The cutting lathe is the device that holds the turntable and cutting head in place and moves them across the vinyl blank as the grooves are cut. It is typically a heavy, precision-machined device that can support the weight of the turntable and cutting head while providing smooth, precise movement.
- Audio source: The audio source provides the electrical signal that is converted into the grooves on the vinyl blank. This can be a record player, a CD player, or a digital audio file.
- Equalizer: An equalizer is used to adjust the frequency response of the audio source to ensure that the grooves are cut with the correct depth and width.
- Monitor speakers: Monitor speakers are used to hear the audio being cut and to monitor the progress of the cutting process.
- Headphone: Headphones are often used in addition to monitor speakers to allow the operator to hear the audio more clearly and to isolate the sound from the surrounding environment.
Prepare your audio.
Before you can start cutting vinyl, you need to prepare your audio source. This involves making sure that the audio is clean and free of noise, and that it is properly mastered to ensure that the grooves are cut with the correct depth and width.
Here are a few things to keep in mind when preparing your audio:
- Make sure that the audio is clean and free of noise. Any noise that is present in the audio will be transferred to the vinyl blank, and it will be more difficult to remove later.
- Properly master your audio. Mastering is the process of adjusting the frequency response, dynamics, and overall sound of the audio to ensure that it sounds its best on vinyl.
- Create a test pressing. A test pressing is a one-off copy of your record that can be used to check the quality of the cut before you commit to a full pressing.
Set up your equipment.
Once you have prepared your audio, you can set up your equipment. Here are a few things to keep in mind when setting up your equipment:
- Place the turntable on a level surface. This will ensure that the vinyl blank is cut evenly.
- Align the cutting head with the center of the turntable. This will ensure that the grooves are cut in the correct location.
- Set the cutting depth and width. The cutting depth and width will determine the loudness and width of the grooves.
- Calibrate your equipment. Calibrating your equipment will ensure that the grooves are cut with the correct depth and width.
Choosing the Right Equipment
Selecting the appropriate equipment is paramount for successful vinyl cutting. Here are some key considerations:
Recording Lathe
The recording lathe is the centerpiece of any vinyl cutting setup. It consists of a rotating turntable, a cutting stylus, and a cutting head that moves the stylus across the record surface. Choose a lathe that is precise, reliable, and has the necessary features to accommodate your cutting needs.
Stylus and Cutting Heads
The stylus and cutting head are essential components that determine the quality of the cut. The stylus shape and material will influence the sound and groove width. Choose a stylus that is compatible with your lathe and provides the desired cutting characteristics.
Cutting heads vary in design and performance. Consider the following factors when selecting a cutting head:
| Factor | Considerations |
|---|---|
| Head Type | Moving magnet (MM), moving coil (MC), or variable reluctance (VR) |
| Compliance | Stiffness or flexibility of the suspension system |
| Vertical Tracking Angle (VTA) | Angle at which the stylus contacts the record surface |
| Azimuth Alignment | Proper alignment of the stylus in the groove |
| Frequency Response | Range of frequencies that the head can accurately reproduce |
Preparing the Vinyl Blank
Before you can start cutting your own vinyl records, you need to prepare the vinyl blank. This involves cleaning the blank, centering it on the turntable, and securing it in place.
Cleaning the Vinyl Blank
To clean the vinyl blank, use a soft, lint-free cloth and a mild cleaning solution. Gently wipe the surface of the blank in a circular motion. Be careful not to use too much pressure, as this could damage the blank.
Materials for Cleaning Vinyl Blank:
| Item | Usage |
|---|---|
| Soft lint-free cloth | Wipe the blank gently |
| Mild cleaning solution | Use a small amount to wipe the blank |
Centering the Vinyl Blank on the Turntable
To center the vinyl blank on the turntable, place the blank on the spindle and gently rotate it until it is centered. You can use a centering tool to help you with this process.
Using a Centering Tool:
A centering tool is a small, round tool that helps you to center the vinyl blank on the turntable. To use a centering tool, place the tool on the spindle and then place the vinyl blank on top of the tool. Rotate the blank until it is centered on the tool.
Securing the Vinyl Blank in Place
Once the vinyl blank is centered on the turntable, you need to secure it in place. This can be done using a vacuum hold-down or a clamp. A vacuum hold-down is a device that creates a vacuum on the surface of the blank, which holds it in place. A clamp is a device that clamps the blank to the turntable.
Using a Vacuum Hold-Down:
A vacuum hold-down is a device that creates a vacuum on the surface of the blank, which holds it in place. To use a vacuum hold-down, place the hold-down on the surface of the blank and then turn on the vacuum. The vacuum will create a suction that will hold the blank in place.
Using a Clamp:
A clamp is a device that clamps the blank to the turntable. To use a clamp, place the clamp on the blank and then tighten the clamp. The clamp will hold the blank in place.
Setting Up the Cutting Head
1. Align the Cutter Head
Ensure the cutting head is perpendicular to the record surface. Use an alignment protractor or a specific tool provided by the manufacturer to achieve precise alignment. Misalignment can cause groove distortion and poor sound quality.
2. Adjust the Cutting Depth
Set the cutting depth according to the specific vinyl formulation and master recording. A deeper groove produces louder sound, while a shallower groove provides a wider dynamic range. Consult the manufacturer’s specifications for recommended cutting depths.
3. Calibrate the Cutting Level
Set the cutting level to achieve an optimal signal-to-noise ratio. Too high a level may cause distortion, while too low a level can result in a weak and noisy recording. Use a test cut and adjust the cutting level until the playback yields balanced sound with minimal distortion.
4. Fine-Tune the Cutting Parameters
| Parameter | Effect | Adjustment |
|---|---|---|
| Stylus Radius | Frequency response, groove width | Use a larger radius for higher frequencies, smaller radius for lower frequencies |
| Stylus Angle | Tracking ability, groove shape | Adjust the angle to minimize distortion and groove wear |
| Vertical Tracking Force | Stylus-groove contact pressure | Set the force to prevent stylus skipping or excessive groove wear |
| Cutting Speed | Groove spacing, sound quality | Higher speeds create narrower grooves, resulting in a more detailed sound |
Cutting the Master Groove
The master groove is the first step in the vinyl record-making process. It is cut into a lacquer disc, which is then used to create metal stampers for pressing the vinyl records.
The master groove is cut using a lathe, which is a machine that spins the lacquer disc at a high speed while a cutting stylus moves across the surface of the disc. The stylus is attached to a piezoelectric transducer, which converts the electrical signals from the recording into mechanical vibrations. These vibrations cause the stylus to cut a groove into the lacquer disc.
The depth and width of the groove are determined by the amplitude of the electrical signal. The higher the amplitude, the deeper and wider the groove. The frequency of the electrical signal determines the pitch of the sound. The higher the frequency, the higher the pitch.
The master groove is a very precise recording. It must be cut with great accuracy in order to ensure that the vinyl records that are pressed from it will sound good. The master groove is also very fragile, and it can be easily damaged if it is not handled properly.
###
5. Stylus Types
There are two main types of styli used for cutting master grooves:
| Type | Description |
|---|---|
| Mono | Cuts a single groove that contains both the left and right channels of the audio signal. |
| Stereo | Cuts two grooves, one for the left channel and one for the right channel of the audio signal. |
Mono styli are less expensive than stereo styli, but they produce records that have less separation between the left and right channels. Stereo styli produce records that have better separation between the left and right channels, but they are more expensive.
The type of stylus used for cutting a master groove will depend on the desired sound quality and budget.
Equalizing and Amplification
Equalization is the process of adjusting the frequency response of the audio signal to compensate for the frequency response of the cutting head and the vinyl record. This is necessary to ensure that the recorded sound is accurate and has the desired frequency balance.
Amplification is the process of increasing the level of the audio signal to the appropriate level for driving the cutting head. The level of amplification must be carefully controlled to avoid overloading the cutting head and causing distortion.
Equalization
The most common equalization curve for vinyl records is the RIAA curve. This curve was developed in the early days of vinyl records to compensate for the frequency response of the cutting head and the vinyl record. The RIAA curve is a roll-off curve that progressively rolls off the high frequencies as the frequency increases.
Amplification
The amount of amplification required will depend on the level of the audio signal and the input sensitivity of the cutting head. It is important to use the correct amount of amplification to avoid overloading the cutting head and causing distortion.
Equalization and Amplification Table
| Parameter | Value |
|---|---|
| EQ Curve | RIAA |
| EQ Roll-off | -20 dB/decade |
| Input Sensitivity | -10 dBV |
| Output Level | +6 dBV |
Monitoring the Cut
Monitoring the cut is crucial to ensure a high-quality recording. While there are several methods, using headphones or speakers connected to the cutting amplifier is the most common:
- Headphones: Ideal for isolating audio, eliminating ambient noise and room reflections.
- Speakers: Provide a more realistic representation of the cut as it will sound in real-world playback systems.
Listening for
When monitoring the cut, pay attention to the following aspects:
- Overall balance: Ensure proper level balance between instruments and vocals.
- Clarity and detail: Listen for any distortion, sibilance, or frequency imbalances that may affect the listening experience.
- Stereo image: Verify that instruments and vocals are panned correctly and create a cohesive stereo image.
- Transitions: Check for smooth transitions between tracks, especially when manually cutting.
- Volume consistency: Monitor volume levels to ensure consistency throughout the recording.
- Groove noise: Listen for any excessive groove noise that may indicate issues with the stylus or cutting parameters.
- Frequency response: Use reference recordings or a frequency analyzer to ensure the cut accurately reproduces the entire frequency spectrum.
Table: Headphones vs. Speakers
| Characteristic | Headphones | Speakers |
|---|---|---|
| Isolation | Excellent | Moderate |
| Accuracy | High | Variable (room acoustics) |
| Stereo image | Limited | Lifelike |
| Convenience | High | Moderate |
Creating the Stampers
The next step in the vinyl record production process is creating the stampers, which are the metal molds used to press the vinyl records. The stampers are created from a master recording, which is a high-quality recording of the music that is to be pressed onto the vinyl record.
The master recording is first transferred to a copper-plated cylinder, which is then used to create a negative mold. The negative mold is then used to create a positive mold, which is then used to create the stampers.
The stampers are made of a nickel-plated alloy, and they are very precise. The stampers are used to press the vinyl records, and they are responsible for the quality of the sound that is produced.
The process of creating the stampers is a complex one, and it requires a great deal of skill. The stampers are essential for the production of high-quality vinyl records, and they are a vital part of the vinyl record production process.
8. Electroplating
The negative mold is then electroplated with nickel to create a positive mold. The positive mold is then used to create the stampers, which are also made of nickel.
The electroplating process is a complex one, and it requires careful control of the temperature, the pH of the solution, and the current density. The electroplating process can take several hours to complete, and it is essential to ensure that the stampers are of the highest quality.
The stampers are then inspected for defects, and they are then used to press the vinyl records.
| Step | Description |
|---|---|
| 1 | The master recording is transferred to a copper-plated cylinder. |
| 2 | The copper-plated cylinder is used to create a negative mold. |
| 3 | The negative mold is used to create a positive mold. |
| 4 | The positive mold is used to create the stampers. |
| 5 | The stampers are electroplated with nickel. |
| 6 | The stampers are inspected for defects. |
| 7 | The stampers are used to press the vinyl records. |
Pressing the Records
Once the lacquer is cut, it’s time to create the actual vinyl records. This process requires:
- Metal stampers
- A vinyl press
- Polyvinyl chloride (PVC) pellets
Creating the Metal Stampers
The lacquer disc is coated with a thin layer of silver, and then an electroplating process is used to create a negative nickel stamper. This stamper is used to create a positive metal stamper, which is the mold from which the vinyl records will be pressed.
Preparing the Vinyl Press
The vinyl press consists of two heated platens and a turntable. The stampers are mounted on the platens, and the turntable holds the PVC pellets.
Pressing the Vinyl
The turntable rotates the PVC pellets into the press, where they are heated and molded by the stampers. The resulting vinyl record is cooled and ejected from the press.
Post-Pressing Processes
Once the records are pressed, they undergo several post-processing steps to remove any excess vinyl, clean the surface, and apply a label.
Center Hole Punching
The center hole of the record is punched out using a special machine.
Flash Trimming
Any excess vinyl around the edges of the record is trimmed off.
Cleaning
The records are cleaned to remove any dust or debris.
Labeling
The records are labeled with the artist, title, and other relevant information.
| Pressing Speed | Output |
|---|---|
| 120 RPM | 300-500 records per hour |
| 180 RPM | 600-1000 records per hour |
