A push block for a table saw is an essential safety tool that provides control and protection when cutting wood. This guide covers the key aspects of creating a custom push block, including optimal dimensions, ergonomic design features, materials, and safety accessories. By following these instructions, woodworkers can craft a push block that enhances safety and efficiency during table saw operations.
What Are the Optimal Dimensions for a Table Saw Push Block?
When crafting a push block for your table saw, getting the dimensions right is crucial for both safety and effectiveness. Here are the recommended measurements:
- Length: 15 inches
- Width: 2-3/4 inches
- Height: 5-1/2 inches
These dimensions are carefully chosen to:
- Distribute pressure evenly along the workpiece
- Reduce the risk of kickback
- Provide a safe distance between your hand and the blade
Remember, while these are optimal dimensions, you can adjust slightly based on your specific needs and comfort level.
How to Design an Ergonomic Push Block?
An ergonomic design is key to a comfortable and safe push block. Consider incorporating these features:
-
Tilted Comfort Grip Handle: This keeps your hands angled away from the cutting tool and allows for constant pressure on the workpiece.
-
Angled Support Foot: Can be lowered for extra tall or thin cuts, enhancing control and stability.
-
Back Miter and Longer Angled Front Cut: Improves ergonomics and reduces overall weight.
-
Hand Grab or Hole: Near the back miter for improved grip and control.
| Feature | Purpose |
|---|---|
| Tilted Handle | Safety and pressure control |
| Support Foot | Stability for various cut types |
| Back Miter | Ergonomics and weight reduction |
| Hand Grab | Additional control point |
What Materials Should Be Used for Push Block Construction?
Choosing the right materials is crucial for durability and effectiveness. Here are the best options:
- Hardwood: Ideal for the handle and base due to its density and durability.
- Plywood: 3/4 inch Baltic birch plywood is recommended for the main body.
- High-Impact Molded Plastic: Can be used for handle and base, offering durability and light weight.
Each material has its advantages:
- Hardwood provides a solid, long-lasting base
- Plywood offers stability and is easy to work with
- Plastic can reduce overall weight while maintaining strength
Which Safety Accessories Should Be Integrated into the Push Block Design?
To enhance safety, incorporate these accessories into your push block:
- Anti-Slip Surfaces:
- Foam rubber or composite rubber pads with podular patterns
-
Diamond Grip or non-slip soft plastic knobs on the underside
-
Ergonomic Hand Grips:
- Comfort grip handles
-
Strategically placed hand holes
-
Sacrificial Retractable Heel:
- Provides extra forward control
- Helps prevent tear-out
These features work together to ensure a secure grip on the workpiece and maintain control throughout the cut.
How to Customize Push Blocks for Various Table Saw Configurations?
To make your push block versatile for different table saw setups:
- Implement an Adjustable Multi-Leg Design:
- Use interchangeable legs for different thicknesses (1\”, 1/2\”, 1/4\”, 1/8\”)
-
Allows customization for various job requirements and blade types
-
Create a Customizable Push Area:
- Ensure the push area is on the same plane as the right side of the block
-
Prevents hanging on the saw fence, especially useful for thin stock
-
Add Sandpaper for Enhanced Grip:
- Attach sandpaper to the bottom of the push block
- Improves control, particularly for thin strips and repeatable cuts
By incorporating these customization options, your push block can adapt to a wide range of cutting scenarios, enhancing both its versatility and your safety.
What Are the Steps to Make a Push Block for a Table Saw?
Follow these steps to create your custom push block:
- Gather Materials:
- Hardwood or plywood for the body
- Rubber or foam for anti-slip surfaces
-
Screws and glue for assembly
-
Cut the Main Body:
- Use the dimensions outlined earlier (15\” x 2-3/4\” x 5-1/2\”)
-
Cut the back miter and angled front for ergonomics
-
Create the Handle:
- Shape the handle for a comfortable grip
-
Ensure it’s tilted for safety and control
-
Add Anti-Slip Surfaces:
- Attach rubber or foam to the bottom
-
Consider adding a retractable heel for extra control
-
Install Safety Features:
- Add hand grabs or holes for improved grip
-
Ensure all edges are smooth to prevent splinters
-
Test and Adjust:
- Try the push block on scrap wood
- Make any necessary adjustments for comfort and safety
By following these steps, you’ll create a custom push block tailored to your needs and table saw configuration.
Remember, safety should always be your top priority when working with power tools. A well-designed push block is an essential part of your safety equipment, helping to keep your hands away from the blade while maintaining control of your workpiece.
