Selecting the Right Hand Saw for Plywood

The key to successfully hand sawing plywood starts with the right tool. Not all hand saws are created equal, especially when it comes to working with plywood. You need a saw designed to minimize splintering and provide a smooth cut. Here’s what to look for when choosing the best hand saw for plywood:

Tooth Design and Pitch

• Tooth Count (TPI): The number of teeth per inch (TPI) is crucial. For plywood, a higher TPI is better. A saw with 7-10 TPI is good for thicker plywood, while 12-15 TPI or higher is preferable for thinner sheets. More teeth create a finer cut, reducing the likelihood of splintering.

• Tooth Pattern: Consider the tooth pattern. Crosscut saws are designed for cross cutting plywood by hand (cutting across the grain), while rip saws are for rip cutting plywood by hand (cutting along the grain). A universal saw, sometimes called a general-purpose saw, can handle both, but it may not be as efficient as a dedicated crosscut saw for plywood.

• Impulse Hardened Teeth: Saws with impulse-hardened teeth stay sharp longer. This is a great advantage when working with plywood, which can dull blades quickly.

Saw Size and Type

• Length: A longer saw (20-26 inches) is generally better for thicker plywood, as it provides a longer stroke and more efficient cutting. A shorter saw (15-20 inches) might be more manageable for hand cutting thin plywood.
• Japanese Pull Saws: Many woodworkers prefer Japanese pull saws (like the Ryoba or Kataba) for plywood. These saws cut on the pull stroke, which results in cleaner cuts and less splintering, especially when cutting plywood manually.

Handle Comfort and Ergonomics

• A comfortable handle is essential, especially for larger projects. Look for handles made of wood or a durable synthetic material with a good grip.
• The handle should fit well in your hand, allowing for a firm and controlled grip.

Preparing Plywood for Hand Sawing

Proper preparation is vital to achieving clean, accurate cuts. This includes marking the cut line, securing the plywood, and taking measures to reduce splintering.

Marking the Cut Line

• Use a sharp pencil or marking knife to mark the cut line clearly. A marking knife creates a shallow groove, which helps guide the saw and prevent it from wandering.
• Use a square or combination square to ensure the cut line is perfectly straight.
• For curved cuts, use a compass or template to draw the desired shape.

Securing the Plywood

• Secure the plywood firmly to a workbench or sawhorses using clamps. Make sure the plywood is fully supported to prevent it from flexing or vibrating during cutting.
• Place a sacrificial piece of wood underneath the plywood along the cut line. This helps prevent splintering on the underside of the plywood.

Preventing Splintering

• Masking Tape: Apply masking tape along the cut line on both sides of the plywood. This helps hold the surface fibers together and reduces splintering.
• Scoring the Cut Line: Before sawing, score the cut line with a utility knife or sharp chisel. This creates a clean edge and prevents the saw from tearing the wood fibers.
• Cutting Technique: Use a shallow angle for the first few strokes to establish the cut line. This also helps prevent splintering.

Mastering Plywood Hand Saw Techniques

Starting the Cut

• The Knuckle Guide: Place your thumb or knuckle along the cut line to guide the saw for the first few strokes. This helps keep the saw on track and prevents it from slipping.
• Shallow Angle: Start the cut at a shallow angle (around 15-20 degrees). Use short, controlled strokes to establish the cut line.
• Gentle Pressure: Apply gentle pressure to the saw. Avoid forcing the saw, as this can cause it to jump or splinter the wood.

Maintaining a Straight Cut

• Focus on the Line: Keep your eye on the cut line and make small adjustments as needed to keep the saw on track.
• Consistent Angle: Maintain a consistent angle throughout the cut. Varying the angle can cause the cut to wander.
• Body Position: Position your body so that you are cutting straight down the line. Avoid twisting or leaning, as this can affect the accuracy of the cut.

Cutting Techniques for Different Plywood Thicknesses

• Thin Plywood (1/4 inch or less): Use a fine-toothed saw (15 TPI or higher) and apply light pressure. Support the plywood well and use masking tape to prevent splintering.
• Medium Plywood (1/2 to 3/4 inch): Use a crosscut saw with 10-12 TPI. Apply moderate pressure and maintain a consistent angle.
• Thick Plywood (1 inch or more): Use a rip saw with 6-8 TPI for cutting along the grain and a crosscut saw with 8-10 TPI for cutting across the grain. Apply firm pressure and use a longer stroke.

Tips for Hand Sawing Plywood Straight

• Practice: The more you practice, the better you will become at sawing straight. Start with scrap pieces of plywood to hone your skills.
• Sharp Saw: A sharp saw is essential for cutting straight. Dull saws require more force, which can lead to inaccurate cuts.
• Good Lighting: Ensure you have adequate lighting so you can see the cut line clearly.
• Take Breaks: If you are working on a large project, take breaks to avoid fatigue. Fatigue can lead to mistakes.

Rip Cutting Versus Cross Cutting

• Rip Cutting: This involves cutting with the grain of the wood. Use a rip saw (fewer teeth, deeper gullets) for this. The technique involves guiding the saw along the grain, letting the saw do the work.
• Cross Cutting: This involves cutting against the grain of the wood. Use a crosscut saw (more teeth, shallower gullets) for this. Apply steady pressure and focus on maintaining a clean, straight line.

Avoiding Common Mistakes When Using a Hand Saw for Plywood Projects

Even with the right tools and techniques, mistakes can happen. Here are some common pitfalls and how to avoid them:

Splintering

• Cause: Using a dull saw, cutting too quickly, or not supporting the plywood properly.
• Prevention: Use a sharp saw, cut slowly and steadily, support the plywood well, and use masking tape or score the cut line.

Uneven Cuts

• Cause: Not keeping the saw on the cut line, varying the angle of the saw, or using a warped saw.
• Prevention: Focus on the cut line, maintain a consistent angle, and use a high-quality, straight saw.

Saw Binding

• Cause: The saw blade getting pinched in the cut, often due to the plywood flexing or closing up as you cut.
• Prevention: Use wedges to keep the cut open, support the plywood well, and avoid forcing the saw.

Fatigue

• Cause: Working for long periods without taking breaks, using a saw that is too heavy or awkward, or not using proper body mechanics.
• Prevention: Take frequent breaks, choose a saw that is comfortable to use, and maintain good posture.

Finishing the Cut

• As you approach the end of the cut, slow down and apply less pressure. This helps prevent splintering on the exit side of the plywood.
• Support the waste piece of plywood to prevent it from breaking off prematurely, which can also cause splintering.

Safety Considerations

• Always wear safety glasses to protect your eyes from sawdust and flying debris.
• Use a dust mask or respirator to avoid inhaling sawdust.
• Wear gloves to protect your hands from splinters and sharp edges.
• Be aware of your surroundings and keep your work area clear of obstacles.

Maintaining Your Hand Saw

• Keep your saw sharp by sharpening it regularly. A dull saw is more difficult to use and can lead to inaccurate cuts.
• Clean your saw after each use to remove sawdust and debris.
• Store your saw in a dry place to prevent rust and corrosion.

Examples of Using a Hand Saw for Plywood Projects

The techniques described above can be used for many using a hand saw for plywood projects. Here are some examples:

• Building a Bookshelf: Plywood is often used for shelves and sides. A hand saw can make accurate cuts.
• Making a Cabinet: For smaller cabinets or components, a hand saw is suitable.
• Craft Projects: Smaller, intricate projects benefit from the control of a hand saw.
