Once the mitre jig is built, you can start using it for cutting precise mitre angles on your table saw. Remember to always follow safety precautions and use the mitre jig with caution.
Step 1: Measure and Cut the Base
The first step in making a mitre jig for a table saw is to measure and cut the base. The base of the jig should be made from a sturdy and flat material, such as plywood or MDF.
Start by measuring the width and length of the table saw’s miter slot. This will determine the size of the base. The base should be slightly larger than the miter slot to ensure a snug fit.
Once you have the measurements, mark them on the plywood or MDF and use a circular saw or table saw to cut out the base. Make sure to cut along the lines accurately to create a square or rectangular shape.
After cutting the base, use sandpaper to smooth out any rough edges and ensure a clean finish. It is important for the base to be flat and smooth to ensure accurate cuts.
Step 2: Create the Mitre Slots
After measuring and marking the locations for your mitre slots on the table saw surface, it’s time to create the slots. Follow these steps:
- Safety first: Before starting any work on the table saw, make sure you have your safety goggles and ear protection on. Clear the area of any debris or clutter.
- Set up the dado blade: Choose a dado blade that matches the width and depth of the mitre slots you want to create. Install the dado blade carefully, following the manufacturer’s instructions.
- Adjust the blade height: Raise the table saw blade to the desired height for the mitre slots. Take your time to get this measurement right, as it will affect the fit of your mitre gauge.
- Make test cuts: Using a piece of scrap wood, make test cuts to ensure that the blade height is correct and the width of the cut matches your marking.
- Make the first pass: Position the table saw fence so that the blade will cut along one side of the marked line for the mitre slot. Make the first pass, cutting only halfway through the table saw surface.
- Make the second pass: Move the fence to the opposite side of the marked line and make a second pass, again cutting halfway through the table saw surface.
- Clear out the waste: With a chisel or a router plane, carefully remove the waste wood between the two cuts to create the full width of the mitre slot. Take your time and work slowly to avoid any mistakes.
- Check the fit: Test the fit of your mitre gauge in the created slots. It should slide smoothly without any wobbling or excessive play.
- Repeat for the remaining slots: Repeat the above steps for each additional mitre slot you want to create on the table saw surface.
Once you have created all the mitre slots, you can move on to the next step of constructing your mitre jig.
