Making angled cuts without power tools may be a bit cumbersome, but they are possible. If you don’t have a miter saw and want to learn how to cut a 45 degree angle without a miter saw, then you are precisely in the right place. 

In this article, I have explained the cutting process as easy as I could. I hope after reading this article, you won’t have any issues while making a 45 degree angled cut without a miter saw. I am sure you must be excited; therefore, let’s not waste any more time and jump straight to the tutorial. 

Before we start learning how to cut a 45 degree angle without a miter saw, you will need a few things for the project. So before starting the project, you need to have the following items as they will have you finish the job efficiently and professionally. 

Things You Will Need to Make a 45 Degree Angle Without Miter Saw

Here is a list of items required for cutting miter angles. 

  • Miter Box (Makes things much easier)
  • A sharp woodworking pencil (Must)
  • Protractor (Required, but we can still work without it)
  • A hand saw (Must)
  • A compass (Completely optional)

How to Cut a 45 Degree Angle Without a Miter Saw (Using Miter Box)

We will start learning how to cut trim at a 45 degree angle without a miter saw using a miter box. It is probably one of the most basic and most straightforward methods that almost everyone can follow. 

While following this technique, you will need to have a miter box. You can make one for yourself if you don’t have one. However, there are some decent miter boxes available on different online stores such as amazon. 

Step 1 Put the trim or any other workpiece inside the miter box with the finish side facing up.

Step 2 Guide your hand saw using the grooves on the miter box at a 45 degree angle. 

Step 3 Start cutting the piece but make sure to let the miter box saw do its job without applying too much pressure. 

Step 4 Remove the workpiece and repeat the process for another one

It will help you make those clean 45 degree angled cuts in no time. It is the most basic way to make miter cuts. However, some projects may require a bit bigger and broader workpieces at a 45 degree angle. 

Due to the larger size of the workpiece, you may not be able to use your miter box. Under such conditions, you will need to use an alternate method for making 45 degree cuts. If you want to learn cutting miter angles without a miter saw or miter box, follow the below methods.

Just as I mentioned earlier, sometimes the workpiece can be too large for a regular miter box. Therefore, you will need to use alternate methods for making the 45 degree cuts. Here is a quicker way to finish the job with higher efficiency. 

For this method, you will need a sharp woodworking pencil and a protractor. Protractors are geometry tools that have different angles printed on them. In order to make a clean miter cut, you will need to follow the below method. 

  • Place the protractor on the workpiece carefully.
  • Use your pencil to mark the 45 degree angle. 
  • Make a cut mark with your handsaw.
  • Follow the mark and keep cutting until you get that nice mitered edge. 

This method is slightly advanced than the previous one. Since you are not going to use the miter box and there won’t be any guide except the line, the chance of error increases. With that said, you will need to be extra careful during the whole project to finish it with clarity. 

It is still an easy way to finish the project without a miter saw. However, if you don’t own a protractor and still want to make mitered cuts without a miter saw, let me teach you another method.

45 degree cut through paper folding method

While cutting a 45 degree angle without a miter saw or any other powered tool, we will need a piece of paper. Yes, you hear me right; you will need a piece of paper to assist yourself and finish the job professionally. 

Here is how you can use that piece of paper to mark a 45-degree angle on your workpiece and make that cut. 

  • Grabe one edge of the paper and bring it to its opposite corner
  • Once you do it, you will have a triangular shape in front of you.
  • Turn the triangle upside down. 
  • Put it on the workpiece that you want to cut at 45 degree.
  • Use your sharp pencil and draw a line using the paper as your guide.
  • You can tape the paper on the workpiece if you want 
  • Use your hand saw to cut the piece and get a mitered edge.

After following the technique mentioned above, you will get your desired angle without any issue. If you are worried about the job’s perfection, don’t worry because a piece of paper always gives 45 degrees when folded. 

However, you will need to carefully finish the job because a slight mistake can ruin the project. Apart from that, If you have a lot of time and want to try something unique, you can make a template for yourself.

Making a Miter Angle Template (using a Compass)

Before even reading this method, I want to tell you that this is entirely optional and will require a bit of effort and maths to make the template. However, this method ensures an insane level of accuracy provided that you have mastered the art of using a hand saw. 

In this method, we will be using a compass to make a template first. After making a template, we will paste it on the workpiece and start the project. Here is a step-by-step tutorial on how to cut a 45 degree angle without a miter saw (using a compass). 

  • Take your compass (equipped with a pencil)  and make an arc on a piece of paper.
  • Put the needle of the compass on one side of the arc and draw an intersect.
  • Put the needle in the middle of an intersection and draw another intersect
  • Using these two intersections, draw a 90-degree angle 
  • Bisect the 90-degree angle to get a 45 degree
  • Erase all unwanted lines and only leave the 45-degree angle
  • Use this as a template and cut the trim, baseboard, or any other workpiece.

I know this may be a little bit complicated, but this method was a bonus. Besides that, you can use other tools to cut 45-degree angles. All you need to do is be creative and use the tools around you to finish the project.
