Steps to Make a Dado Jig
Building a dado jig for your table saw is a simple process that can help you create precise and clean dado cuts. Follow these steps to make your own dado jig:
1. Gather the Materials
Before you start building your dado jig, gather the following materials:
- 3/4″ plywood sheet
- 1/4″ plywood sheet
- Measuring tape
- Straight edge clamps
- Screwdriver
- Drill
- Screws
2. Measure and Cut the Plywood
Using a measuring tape, measure the dimensions of your table saw’s base plate. Cut a piece of 3/4″ plywood to match these dimensions. This will be the main body of your dado jig.
Next, measure and cut a piece of 1/4″ plywood to the same dimensions as the 3/4″ plywood. This will serve as the backer board for your dado jig.
3. Attach the Backer Board
Place the 1/4″ plywood backer board on top of the 3/4″ plywood main body, ensuring they are aligned. Use straight edge clamps to hold the two pieces together.
Drill pilot holes through both pieces of plywood, then secure them together using screws.
4. Mark the Dado Width
Using a measuring tape or a dado set, mark the desired width of your dado on the backer board. Ensure that the dado width is centered on the jig.
5. Attach the Guide Strip
Measure the distance from the blade of your table saw to the outside edge of the dado set. Cut a piece of scrap plywood to this length. This will be the guide strip for your dado jig.
Align the guide strip with the marked dado width on the backer board. Secure it in place using screws.
6. Test and Adjust
Now that your dado jig is complete, it’s time to test it. Set the fence on your table saw to the desired width of your dado, and make a test cut using the dado jig.
If the dado is not the correct width, you may need to adjust the guide strip and retest until you achieve the desired results.
By following these steps, you can easily create a dado jig for your table saw that will help you achieve accurate and clean dado cuts in your woodworking projects.
Step 1: Measure and Mark the Wood
The first step in making a dado jig for your table saw is to measure and mark the wood that will be used for the jig. This step is crucial in ensuring that the jig will fit correctly and provide accurate dados.
Start by selecting a suitable piece of wood for the jig. It should be sturdy and straight, as it will serve as the foundation of the jig. Use a tape measure to measure the desired length and width of the jig. Take into account the size of the dados you intend to make, as well as any extra space needed for clamps or guides.
Once you have determined the measurements, use a pencil or a marking knife to mark the wood accordingly. Make sure to mark the edges and reference points clearly, as this will help during the construction process.
If you plan to make multiple dados of varying sizes, consider labeling each set of markings with corresponding sizes. This will make it easier to identify the correct setup when using the jig in the future.
Remember to double-check your measurements before proceeding to the next step. Accuracy is essential to ensure precise and consistent cuts when using the dado jig.
Step 2: Cut the Wood Pieces
Before you can start building your dado jig, you’ll need to cut the wood pieces to the appropriate sizes. Here’s what you’ll need:
| Wood Piece | Size |
|---|---|
| Base | 12 inches long, 4 inches wide, and 1/2 inch thick |
| Front Fence | 12 inches long, 2 inches wide, and 3/4 inch thick |
| Side Fence | 20 inches long, 2 inches wide, and 3/4 inch thick |
| Top Fence | 20 inches long, 3 inches wide, and 3/4 inch thick |
You can use a table saw to cut these pieces to the correct dimensions. Make sure to use a push stick or push block to keep your hands safe while cutting.
Once you have cut the wood pieces to the correct sizes, you’re ready to move on to the next step.
Step 3: Drill Holes for Bolts
Now that we have our measurements marked on the plywood, it’s time to drill holes for the bolts that will attach the fence to the jig. Start by selecting a drill bit that matches the diameter of your bolts. It’s important to select the right size bit to ensure a secure fit.
Next, clamp the plywood to your workbench to prevent it from moving while you drill. Position the drill bit at one of the marked points and apply firm, steady pressure as you drill through the plywood. Repeat this process for each marked point.
Once all the holes are drilled, remove the clamps and double-check that the holes are clean and free of any debris. Use a sandpaper or file to smooth any rough edges if necessary.
Tip: It’s a good idea to use a scrap piece of wood underneath the plywood while drilling to prevent tear-out on the bottom side.
After drilling the holes, take a moment to test fit the bolts. Insert each bolt into its corresponding hole and ensure that it sits flush with the plywood surface. If any holes are too small or misaligned, use a larger drill bit or a file to make them larger.
Note: If you’re using T-nuts instead of bolts, you’ll need to drill larger holes to accommodate the hardware. The size of the holes will depend on the size of the T-nuts you’re using. Follow the manufacturer’s instructions for proper hole size.
Once you’re satisfied with the fit, remove the bolts and set them aside. We’re now ready to move on to the next step: attaching the fence to the jig.
