What You'll Need

Power drill and screws

Table saw jigs can be used for making just the right cut. They can be made to help you make straight, square cuts or they can be used to help you make the perfect angled cut. You can purchase a jig already made or you can make one yourself. The plans range from very simple to difficult and detailed. You should find the plan that best represents what you want the end result to be. This jig can be used for your radial arm saw or you can use it to take with you when you're out and about and need to use your circular saw.

Step 1: Measure and Cut

You will want to make the size that you need to work with, but for the purposes of this article the size should be 12" by 24". Use your straight edge to mark out the rectangular pattern of your jig platform. You will also need to measure out a piece that is 12" by 2". After you have measured and transferred those measurements to the MDF, you can use your saw to cut out the material. Take care to ensure that the edges are straight, as this will be your guideline for many different cuts. The 12" by 2" piece of MDF will be used as a simple straight edge for the jig.

Step 2: Measure and Mark

Mark where the straight edge will be placed. Using a pencil and a straight edge, measure 18 inches in from the left end of your board, or 6 inches from the right.

Step 3: Place and Secure

Place the 12" by 2" length of MDF on the left side of the line you drew in step two. If you want, you can use wood glue to secure it while you mark and drill screws in to secure it permanently. Three screws should be sufficient for this length.  

Step 4: Cut off Excess

Take your saw and cut off the right side of the jig. This is the excess 6 inches on the right of the straight line. You've now completed the jig and are ready to use it.

How to Use It

This jig allows you to get a straight line cut every time that you need it. Simply mark the wood that you are working on and line up the fresh cut side of the jig with the marks. Run your saw blade against the jig in order to create the perfect straight line.

As stated, you can build many different types of jigs for your table arm saw. You can build different sizes of this same jig or incorporate a more difficult jig for your next project.
