Easy Circular Saw Guide Rail

Learn how to build an easy circular saw guide rail with a step-by-step tutorial, measurements, and video. A perfect addition to your workshop.

A circular saw is one of the very basic tools every workshop should have. It is one of the most common beginner power saws and a great tool to use when you are starting in the craft. Due to its versatility, in many cases it can replace a table saw if used correctly.

Circular saws on their own are good at making short precise cuts but when it comes to cutting large workpieces you might struggle a bit. Well, it is doable but difficult. 

Nevertheless, an easier and better option would be to use a circular saw guide rail. Unfortunately, these jigs can be quite expensive. But why not make a guide track for a circular saw by yourself?

Making a saw track is a fairly simple and quick project and it will help you so much in your workshop. You don’t need to buy new tools, you can make a saw track for the circular saw you already have in the workshop.

With the instructions and video provided in this blog post, you will learn step by step how to make a DIY guide for a circular saw. 

I hope you enjoy it!

*Safety is your responsibility. Make sure you know what you’re doing and take all necessary safety precautions while working with power tools. Safety comes first!

Always be cautious and careful when using any power tool. If you are not feeling comfortable with a certain technique look for other options on how to do it.

What you'll need to build the Circular Saw Guide Track

Circular Saw Track
Birch Plywood – (70 x 33,5 x 1,2 cm)
2x Birch Plywood – (3,5 x 2,5 x 1,2 cm)
Handle – 14 cm length
4x wood screws
2x Aluminum guide rails – (70 x 1,4 x 1,2 cm)

Other
14x bolts ø4, 1,6 cm + washers, nuts
Metal Drill Bit ø4,2 mm
Double sided (carpet) tape
Forstner bit ø20 mm

Why should I build a Circular Saw Guide?

There are several reasons why to make a saw track. But there were 2 main ones for me, based on which I decided to build it.

1) Price – You can easily spend hundreds of dollars on a track saw. If you are building a workshop on a budget that is probably not the best way to spend your tool funds. Instead, if you feel like spending the extra money, consider buying a good blade for the circular saw.

This homemade DIY track saw cost me around $15. That is for the material I used. It might be different for you but still, you will be able to build it for a fraction of the price a new track would cost you.

2) Make long straight cuts – I didn’t have a table saw so being able to make long straight cuts was quite a difficult task. Especially when I needed to precisely cut a large plywood sheet.

Note: If you are looking for a track guide that would help you make angle cuts then this guide is not built for that.

How hard is it to build?

Not hard at all!

This is an easy project for beginners requiring very basic tools.
The project is straightforward and the cuts are simple. You can build the entire saw track in a few hours.

This would make a great weekend project.

Do you need a lot of tools to build it?

No, you donť!

Just a circular saw, a hand drill, and a (hand) saw to build it! I used a jigsaw to cut out the main shape of the circular saw track. A jigsaw is great for making short straight cuts, crosscuts and inside corner cuts, however, a hand saw will work just as well.

Let's Start

How to make a Circular Saw Guide Track

Step 1: Make the Circular Saw Guide Base

Before we get into building the guide let me share some information on the material.

The most important piece is the aluminum guide rails (at least one of them). They should be lower than the height of the fully lowered circular saw. In this way, the guide rails don’t interfere with the circular saw and the largest possible saw depth can be used.

Draw the design of the saw guide on the plywood sheet and cut out the shape. The design is available in the video or as a free plan above.

Note: Check the width of your circular saw and adjust the design accordingly.

If you’re going to use a circular saw to cut out the shape of the guide you can use some sort of straight edge to do that. I used an aluminum spirit level.

Although a jigsaw in combination with a jigsaw guide track turned out to be a good way to easily cut out the shape.

Sand all the edges and corners smoothly to get rid of splinters.

Step 2: Attach the Aluminum Guiding Rails

The width of my circular saw is 13,3 cm. Take into account the width of your saw to place the guide rails accordingly.

Measuring the base of a circular saw

Tape one side of the circular saw to leave a bit of extra space between the rails for a better slide.

Cut the aluminum rails to size.

To attach the guide rail to the base I first used a double-sided (carpet) tape. Once the bar was in position I additionally fixed it with countersunk bolts and nuts.

To attach the second guide rail place the circular saw right next to the first one (with the tape on) and fix the second guide rail accordingly following the same steps as before.

Note: A thin aluminum bar can easily bend. Take care while placing the bar on the base.

Step 3: Cut the Slot

This circular saw track does not have a stopper. Neither at the beginning nor at the end. I wanted to have as much usable space on the guide as possible. Although without a stopper you can easily cut through the guide – keep that in mind. 

Place the circular saw where you want to start cutting.
First cut a very shallow slot along with the guide rails just to mark a line.

Cut several “sight holes” along the entire length of the cut. I used a 20mm Forstner bit.
These sight holes will help you to adjust the guide when making a cut.

Once finished with the sight holes cut a slot in the track saw.
Again be mindful there is no stopper.

Sand the slot to get rid of splinters and sand the surface of the guide track for the circular saw to slide easier. I used sandpaper of different grit sizes ranging from P200 to P800.

Step 4: Attach the Handle

I decided to add a handle that goes from the top of the circular saw guide. Using it like that you can press down the guide and fix it in position while cutting (although fixing the guide using clamps would be still needed).

The handle I am using was not high enough and my hand did not fit entirely. So I added additional pieces of plywood to add extra space.

Pre-drill holes for the screws and attach the handle to the base.

How to use a Circular Saw Track

It is quite easy to use a circular saw guide track.

  1. Draw a line on the piece of wood you want to cut.
  2. Place the circular saw track over the line and adjust it accordingly using sight holes.
  3. Use clamps to fix the saw track to a workbench for better stability and accuracy.
  4. Mount the circular saw on the track and slowly make a cut.

Note: Keep in mind on which side of the line you want to make the cut. Also, keep in mind there is no stopper.

DIY Guide For Circular Saw Wrap Up

A circular saw guide rail like this is really easy to make. It is quick to build, easy to set up, and inexpensive compared to circular saw guides you get in the shop. You can really build this track saw for only a few tens of dollars. So why not save some money?

Instead, invest the money and buy yourself a good blade for the circular saw that will help you make clean and accurate cuts. Totally worth it! Also, check this circular saw guide for crosscuts and right-angle cuts.
