5 Easy Steps To Make Sure Your Table Saw Fence Is Square:

There are several steps you can take to begin the process of preparation for checking the measurements. In addition, the most simple and effective way is described here. In this way, I have gained quite a prominent experience with a table saw fence which I am going to share with you.

Step-1 Need Some Geometrical Tools:

Fortunately, you can easily measure the size of a table with a geometric method. But, unfortunately, geometric tools can be a little difficult to collect or buy. Try to use geometric methods. This is the best way to measure accurately. You will not understand the size of the table saw fence to guess your eyes. So, let’s find out the names of what tools are needed.

  • Rip Fence Alignment;
  • Table Blade Alignment;
  • Blade Bevel Angle;
  • Miter Gauge Angle;
  • Rip Scale Indicator.

With these instruments, you need more skill, patience, attention, and time. You may not have an idea about each of the tools. You will get the idea through work from the next steps.

Step-2 Table To Blade Alignment Measurement:

This tool should be placed on the track of the miter slot on the table and measured in parallel. This tool has sharp teeth that will scratch against your wood if it is not on the parallel border. Then you have to look at the abrasion marks of the blade alignment on your surface to understand where there is a lack of measurement.

Mark the ‘X’ on one end of the blade teeth. Take a small part to attach the screw to one end. The screw touches the blade slightly. The part must be less than 2.5*4.5. Now set the miter gauge with the screw near the blade in such a way that it touches slightly. Look at the picture and now rotate the blade.  

Rotate as long as it takes to observe you. The tooth marked X will create pressure with the screw, otherwise, if there is slight air pressure, loosen the clamp more and rotate it again in the same manner. This way you can check if the blade alignment is parallel to the table. Consult a skilled carpenter to get a clearer idea, if you don’t yet understand clearly.

Step-3 Parallel To The Fence Alignment:

Getting an idea of ​​rip fence alignment is the most important tool for measuring table saw fences. Check if it is compatible with the fence and see if it is parallel. Set it with the track for the rip fence of your table. See how to level up the rip fence alignment to your saw fence. With this, you can easily know if your table is so square.

Once the table is parallel to the blade, you will want the table and the fence to be parallel to the blade. It is very easy to do this with the miter slot. Measure with a miter slot, you will see if it is parallel to the upper and lower corner.

Step-4 Miter Gauge Adjustment:

Now it is time to measure with a meter gauge. Set the meter gauge and turn the pointer to zero. This means the meter gauge is fixed at a 90-degree angle with a blade. You can mark it with two different symbols. Now set the two pieces in such a way that one letter is facing upwards and the other is facing downwards, and it is attached to the surface of the miter gauge.  

Now you will see some asymmetrical objects like in the picture. Now try to cut the unequal part and make it equal so that there is no gap. In this way, complete the process with a miter gauge and measure.

Step-5 90 Degrees/45 Degrees Blade Bevel Angle:

The blade bevel angle is a tool to cut your piece at 90 degrees or 45 degrees angle. Many of the same rules apply such as a 90 degrees angle. But it can be required to cut it at a 45-degree angle. The bevel angle is perfectly perpendicular to the cut as per your requirement.

Don’t trust the bevel indicator in your table saw. It is not enough to be accurately set up. It’s easy to set it up at 45-degrees and back it to 90 degrees. You can measure it with a very useful digital angle box. It is the most effective and easy to use I found. You tape it to 0 levels and set it with the blade

The blade turns 45 degrees and the digital box shows the result of the angle. Moreover, you can use normal tools to know the measurement. A digital measuring box may be very expensive to you and it cannot deliver the exact result sometimes.

3 Simple Steps To Make The Table Saw Fence Square:

The biggest issue with a table saw that you have to face is a proper table saw fence. Here I discuss how to solve the problem. And that is to make your table saw fence. The way I make it is very easy, cheap, and quick. 

Step-1 Straight Cut Pieces:

You need a square fence for your table which you can make yourself. Cut a piece by measuring with a miter slot. Cut with a table circular saw. Make sure it is a left and right-side straight cut piece. Clamp up the cut piece for another piece. Then cut another piece of the same size by double-checking. You should take double measures to make sure the size is accurate.

So, now you have the two great pieces, you can make a rough check for 90 degrees. Cut the length equal to the table. It will make you satisfied if the size is suitable for your table.

Step-2 Make A Small Support:

You have to make some square blocks to support the glue of two cut pieces. Make sure the blocks are equal squares. It needs to be 4, 5, or 6 pieces for support. You use them because it links with another piece. 

Now glue the blocks together with a piece of glue. And then shape the rest of the piece and glue it. Apply glue by measuring it exactly with the geometric tool to keep the 90-degree angle. Clean the white glue and clamp it and then check the 90-degree angle properly. You have to wait for a whole day.

You can use screws instead of glue. Although the glue is not permanent, the screw is much more durable. However, screwing is not flexible, you have to manage the machine to drill. 

Step-3 Attach The Fence:

The basic part of making a fence is complete now. Cut the two pieces measuring the table length to attach the fence to the front and back of the table saw. Now clamp the two pieces on either side of the table so that it is parallel to the table. Check temporarily to see if everything is okay. It’s aligned with my table saw blade, which is very important. 

Now you make the two screw holes on each side. Keep the screws tight with the table’s edges so the fence cannot wiggle. It needs to be set in such a way that it can move from left to right and right to left side easily.

Now your square fence-making is great. It’s very accurate and perfect now. It makes you happy because it is aligned with your table saw blade. So this is great, cheap and easy which you can make in a day.
