One of the first power tools many woodworkers recommend for beginners, after a cordless drill, is a jigsaw. Jigsaws are often more affordable and safer than circular saws, offering adjustable blade speeds and the ability to cut a variety of materials. Plus, they have a quicker learning curve.
However, anyone who’s used a jigsaw to crosscut wood knows that achieving accurate cuts can be challenging. It’s difficult to maintain a straight line, and when trimming small amounts from an edge, the jigsaw can tilt, jump, and leave marks on the wood.
This article shows you how to make a simple wooden crosscutting guide (or sled) for your jigsaw, using basic tools. This jig will transform your jigsaw into a precision cutting tool!
Materials and Tools
You’ll need the following to build your jigsaw guide:
- A piece of plywood or MDF (approximately 12″ x 18″)
- Two strips of wood (approximately 1″ x 12″)
- Wood glue
- Screws or nails
- Clamps
- Jigsaw
- Table saw or circular saw (optional, for cutting the base)
- Measuring tape or ruler
- Pencil
- Safety Glasses
Step 1: Cut the Base
Cut a piece of plywood or MDF to serve as the base of the jigsaw guide. A good size is around 12″ x 18″, but you can adjust this depending on the size of your jigsaw and the cuts you plan to make. Make sure the base is square.
Step 2: Attach the Guide Strips
Cut two strips of wood, each approximately 1″ x 12″. These strips will act as the guides for your jigsaw. Apply wood glue to one side of each strip and attach them to the base, parallel to each other. The distance between the strips should be slightly wider than the base of your jigsaw, allowing it to slide freely between them. Use clamps to hold the strips in place while the glue dries. For added strength, you can also use screws or nails to secure the strips.
Step 3: Create the Kerf
Once the glue is dry, place your jigsaw between the guide strips. With the jigsaw running, carefully cut a kerf (a slot) through the base of the sled. This kerf will serve as your cutting line.
Step 4: Add a Backstop (Optional)
For added support and accuracy, you can add a backstop to your jigsaw guide. Cut a piece of wood the same width as the base and attach it to the back edge, perpendicular to the guide strips. This will help prevent the wood you’re cutting from shifting during the cut.
Step 5: Test and Adjust
Before using your new jigsaw guide on a project, test it with a scrap piece of wood. Make a cut and check the accuracy. If necessary, adjust the guide strips or the backstop to ensure that your cuts are perfectly square.
Tips for Using Your Jigsaw Guide
- Always wear safety glasses when using a jigsaw.
- Use clamps to secure the wood you’re cutting to the guide.
- Keep the base of the jigsaw flat against the guide strips for accurate cuts.
- Use a sharp blade for clean cuts.
- Adjust the speed of the jigsaw to match the material you’re cutting.
Advantages of Using a Jigsaw Guide
- Improved Accuracy: The guide helps you make straight, accurate cuts, even on difficult materials.
- Increased Safety: The guide helps prevent the jigsaw from jumping or tilting, reducing the risk of injury.
- Versatility: The guide can be used to cut a variety of materials, including wood, plastic, and metal.
- Professional Results: With a jigsaw guide, you can achieve professional-looking results with your jigsaw.
