Getting Started with Sawing: The Musical Saw
Playing a musical saw is a unique and rewarding experience. It produces a beautiful, ethereal tone that can evoke a sense of wonder. Unlike its woodworking cousins, the musical saw is designed to be bent and played with a bow. It’s a surprisingly accessible instrument, and with a bit of practice, you can create enchanting melodies.
What is a Musical Saw?
A musical saw is essentially a piece of flexible steel, similar to a handsaw used in woodworking, but without teeth. It’s played by bowing the smooth edge while bending the blade to alter the pitch. The sound produced is a clear, resonant tone, often described as haunting or otherworldly.
Choosing the Right Saw for Music
Not every handsaw will work for making music. For playing, you need a saw specifically designed or adapted for musical purposes. These saws are typically:
- Flexible: They need to bend smoothly without breaking.
- Thin: Thinner steel vibrates more readily, producing a clearer tone.
- Smooth-edged: The cutting edge is removed or smoothed to allow bowing.
- Of a suitable length: Longer saws generally produce lower pitches.
While you can find dedicated musical saws, many beginners start with a repurposed woodworking handsaw that fits these criteria. It’s a great way to try out the instrument before investing in a specialized model.
Essential Accessories for Saw Music
To begin your musical saw journey, you’ll need a few key items:
- A Bow: A cello or bass bow is commonly used. It needs to be in good condition and properly rosined.
- A Mallet or Hammer: For striking the saw to produce different sounds or accents.
- A Stool: To sit comfortably while playing.
- Rosin: For the bow hair to grip the saw blade.
Basic Sawing Techniques for Music
Once you have your saw and bow, it’s time to make some noise! The fundamental technique involves bowing the smooth edge of the saw while bending it to create different notes.
Holding the Saw
The way you hold the saw is crucial for both sound production and comfort.
- Position: Sit on a stool with the handle of the saw held between your knees. This provides stability and allows you to control the bend of the blade with your legs.
- Blade Angle: The blade should be held at an angle, not perfectly vertical. This helps the bow engage the surface smoothly.
- Grip: Hold the tip of the saw blade with your non-bowing hand. Your thumb should be on one side of the blade and your fingers on the other, allowing you to control the bend.
Bowing the Saw
This is where the magic happens. The bow is drawn across the smooth edge of the saw blade.
- Bow Pressure: Apply consistent, gentle pressure with the bow. Too much pressure will cause scratchy sounds or stop the vibration. Too little pressure will result in a weak or no sound.
- Bow Speed: A steady, even bow speed is key. Experiment to find the right balance.
- Vibrato: To create a singing quality, introduce a slight, controlled vibrato by moving your bowing wrist back and forth.
Pitch Control: Bending the Blade
The pitch of the note is determined by how much you bend the saw blade.
- Sharper Bend: Bending the saw more sharply produces a higher pitch.
- Gentler Bend: A less pronounced bend results in a lower pitch.
Practice transitioning between different bends smoothly to create legato melodies. Your knees will be your primary tools for adjusting the bend.
Striking the Saw
While bowing is the primary method, striking the saw with a mallet can produce percussive effects or different tonal qualities.
- Placement: Strike the blade at different points along its length. Striking closer to the handle generally produces a sharper, more percussive sound, while striking further out can create a more resonant tone.
- Force: Experiment with the force of your strikes. Gentle taps produce delicate sounds, while firmer strikes create stronger accents.
Exploring Different Types of Saws for Music and Beyond
While this guide focuses on the musical saw, it’s worth noting the vast world of woodworking saws. Many of these share principles of blade and tooth design, even if their purpose differs entirely.
Woodworking Saws: A Brief Overview
Woodworking saws are designed to cut through various materials, primarily wood. They are categorized by their power source and design.
- Handsaws: These are manually operated saws. They are the oldest and most basic type.
- Crosscut Saws: Designed to cut across the grain of wood.
- Rip Saws: Designed to cut along the grain of wood.
- Backsaws: Saws with a stiffening rib on the back, used for finer joinery and cuts requiring accuracy.
- Coping Saws: Small saws with thin blades held in a U-shaped frame, ideal for intricate curves and cut-outs.
- Power Saws: These use electricity or engines to do the cutting.
- Circular Saws: Feature a spinning, toothed disc for fast cuts.
- Jigsaws: Use a reciprocating blade for curved and intricate cuts.
- Reciprocating Saws: Powerful saws with a push-and-pull blade action for demolition and rough cuts.
- Miter Saws: Used for making precise angle cuts, often in conjunction with a circular blade.
- Table Saws: A stationary saw with a blade protruding through a table, used for ripping, crosscutting, and dadoes.
- Band Saws: Feature a continuous loop of toothed metal that runs over two or more wheels, excellent for curves and resawing.
Understanding Saw Blade Types
The effectiveness of any saw, musical or for woodworking, depends heavily on its blade.
- Tooth Geometry: The shape, size, and spacing of teeth are critical. For woodworking, this dictates whether it’s a rip or crosscut saw. For musical saws, the absence of teeth is key.
- Blade Material: High-carbon steel and alloy steel are common. Flexibility and hardness are important considerations.
- Blade Thickness: Thinner blades vibrate more easily, which is beneficial for musical saws. For woodworking, thickness can affect stability and cut quality.
Sawing Techniques for Precision and Control
When you move from the musical saw to its woodworking counterparts, the focus shifts to accuracy and efficiency.
Sawing Straight Lines
Achieving a straight cut is fundamental in woodworking.
- Marking: Use a pencil and a straight edge or a marking knife to draw a clear, precise line on the wood.
- Setup: Position the wood securely on a workbench or sawhorses.
- Starting the Cut:
- For handsaws, start by creating a slight kerf (groove) with a few backstrokes.
- Align the saw blade with your marked line.
- Use smooth, steady strokes, letting the saw do the work.
- Maintaining the Line:
- Keep the saw blade perpendicular to the wood surface.
- As you cut, use your other hand to gently guide the wood and prevent it from binding or moving.
- Look slightly ahead of the blade to anticipate any deviations.
- Finishing the Cut: As you near the end of the cut, ease up on the pressure to prevent the wood from splintering or tearing off. Support the offcut piece to avoid it falling and damaging the cut edge.
Making Precise Cuts with a Saw
Precision involves not just straightness but also accuracy in measurement and the quality of the cut edge.
Techniques for Accuracy
- Measure Twice, Cut Once: This adage is paramount. Double-check all your measurements before making any marks.
- Using a Square: Employ a try square or combination square to ensure your cut lines are perpendicular to the edge of the wood.
- Kerf Awareness: Understand that every saw removes a small amount of material (the kerf). Account for this when marking your cut line. If you want a piece to be exactly a certain length, your cut line should be on the waste side of that measurement.
- Blade Guide: For finer saws like backsaws, rest the saw’s back against a bench hook or a miter box to help guide the blade and ensure accurate angles.
- Controlled Strokes: Avoid forcing the saw. Let the sharp teeth do the cutting. Smooth, consistent strokes are far more effective than brute force.
- Blade Wobble: Prevent the blade from wobbling by keeping it at a consistent angle and applying even pressure.
Saw Blade Types and Their Impact on Precision
The type of saw blade significantly influences the precision of your cut:
| Saw Blade Type | Tooth Count (TPI – Teeth Per Inch) | Best For | Precision Level |
|---|---|---|---|
| Rip Saw | Low (e.g., 4-6 TPI) | Cutting along the grain | Moderate to Good |
| Crosscut Saw | Medium (e.g., 7-10 TPI) | Cutting across the grain | Good |
| Backsaw (Tenon/Dovetail) | High (e.g., 12-20+ TPI) | Fine joinery, precise cuts | Excellent |
| Hacksaw Blade | Variable (often 18-32 TPI) | Metal, plastic (can cut wood if fine) | Good (for its purpose) |
| Coping Saw Blade | Very High (e.g., 15-32 TPI) | Intricate curves, detailed work | Excellent (for curves) |
| Musical Saw (No teeth) | N/A | Musical tones | N/A (sound focus) |
- Higher TPI: Generally leads to smoother cuts and better control, ideal for precision work.
- Lower TPI: Cuts faster but produces a rougher finish, less suitable for precise joinery.
Saw Safety Tips: A Must-Know for All Saw Users
Whether you’re playing a musical saw or cutting wood, safety must always be your top priority.
General Safety Practices
- Wear Safety Glasses: Protect your eyes from flying debris. This is non-negotiable, even for musical saws where small metal fragments could chip off.
- Keep Fingers Clear: Be mindful of where your fingers are at all times. Ensure they are well away from the blade path.
- Secure Your Workpiece: Make sure the material you are cutting is stable and won’t shift during the sawing process.
- Use Sharp Saws: A dull saw requires more force, increasing the risk of slippage and accidents. It also makes the job harder and less enjoyable.
- Know Your Saw: Familiarize yourself with the specific saw you are using and its limitations.
- Maintain a Clean Workspace: Remove clutter that could cause tripping or obstruction.
- Proper Lighting: Ensure you have adequate lighting to see what you are doing clearly.
- Avoid Distractions: Focus on the task at hand. Avoid talking on the phone or engaging in conversations while sawing.
Specific Safety for Musical Saws
- Blade Integrity: Inspect the musical saw blade for any signs of cracking or weakness before each use.
- Controlled Bending: Bend the saw smoothly and gradually. Avoid sudden jerks or over-bending, which could lead to snapping.
- Rosin Management: Keep rosin dust away from your eyes and face.
- Bow Handling: Treat the bow with care. It’s a delicate instrument in itself.
Specific Safety for Woodworking Saws
- Guards: Ensure all safety guards on power saws are in place and functioning correctly.
- Push Sticks: Use push sticks when working with smaller pieces of wood on power saws to keep your hands away from the blade.
- Kickback Awareness: Understand the potential for kickback with power saws and how to avoid it.
- Unplug Power Tools: Always unplug power saws before changing blades or making adjustments.
Making Precise Cuts with a Saw: A Deeper Dive
Achieving truly precise cuts requires a combination of good tools, proper technique, and a keen eye for detail.
Calibrating Your Saws
For woodworking, it’s essential that your measuring tools and your saws are accurate.
- Measuring Tools: Ensure your tape measure, rulers, and squares are not damaged and provide accurate readings.
- Blade Alignment: Check that the blade on power saws is aligned correctly with the fence or miter gauge.
Advanced Sawing Techniques
- Plunge Cuts: For some saws (like jigsaws), making a cut without starting from an edge is possible. This requires specific techniques to avoid damaging the blade or workpiece.
- Jig and Fixture Use: For repetitive precise cuts, creating or using jigs and fixtures can greatly improve accuracy and consistency.
- Chiseling and Sanding: Often, the final touch of precision involves cleaning up a sawn edge with a chisel or sandpaper to remove any slight roughness or saw marks.
The Art of Sawing Straight Lines
This isn’t just about keeping the line; it’s about the quality of the line itself.
- Marking Gauge: For very fine woodworking, a marking gauge can create a shallow groove that acts as a perfect guide for a fine-toothed backsaw.
- Kerf Wobble: To minimize kerf wobble, try to maintain the same angle of the saw blade throughout the stroke. Imagine the saw blade as a vertical plane; keep that plane moving consistently.
- Support the Blade: With handsaws, a gentle side-to-side wobble of the blade can help clear the kerf and prevent binding, but too much wobble will result in an inaccurate cut.
