Ripping a narrow board might seem tricky to do with a circular saw, but it is definitely possible to do this neatly by following a set of simple steps.
Things You'll Need
- A Circular Saw With A Rip-fence.
- A Sacrificial Piece of Wood/Sheet.
- The Narrow Board for Ripping.
- Two Quick-Grip Clamps.
- A Speed Square.
- Masking tape/Painter's tape

Step-By-Step Guide to Ripping Narrow Boards with a Circular Saw
In this section, I'll show you how to use a circular saw for ripping narrow boards in a step-by-step manner.
First, lay down the sacrificial sheet on your work table.
The sacrificial sheet is meant to act as a buffer between the board that needs to be ripped and your work table.
Next, place the board to be ripped on top of the sacrificial sheet and fix masking tape over the board before drawing the mark on it as it will greatly reduce the amount of burr produced and lend you a finer finish after ripping.
Now it's time to mark a line length-wise to help guide you during the ripping process. For marking, make use of a speed square to achieve a straight and accurate line.
Once the line of ripping is marked, clamp the board on the sheet down using two quick grip clamps. Use one clamp in the middle and another on the farther end of the board.
After clamping, adjust the blade height of the circular saw.The blade height should be such that the blade makes a through cut in the board while grazing the sacrificial sheet.
After setting the blade height, you can move on to the ripping.
Before ripping the board, you need to consider the kerf loss. Kerf loss refers to the amount of wood lost while sawing, due to the thickness of the blade.
since the thickness of the blade is usually 1/8th of an inch, you're only looking at a marginal loss. Make sure to place the blade just outside the line that you marked for getting an accurately sized piece after ripping.
Once the blade is placed at the correct position, lock the rip fence in place to begin the ripping.
If you don't have a rip fence, make a straight edge using scrap wood and use it as a guide for cutting.
To rip the board, align the blade with the mark made earlier and switch on the saw.
Use the rip fence to guide the saw along the length of the board.
Upon reaching the middle of the board, remove the quick grip clamp and re-attach it at the end to where you started so you may continue sawing without the board slipping.
Continue sawing till the end and the clamp at the end needs to be unclamped just like in the previous step.
Re-attach that clamp at the middle of the board and resume the ripping.
With that you have completed ripping the narrow board using a circular saw.

Tips to Improve Accuracy While Ripping
- Use a sharp blade with an appropriate number of teeth.
- Make sure the board has a straight edge before ripping. If the board edge is not straight, you cannot use a rip fence to get a straight cut.
- If you are using wet wood or treated lumber, use a blade that's appropriate for that purpose.
How to be Safe While Ripping Using a Circular Saw
- Always wear ear protection and a mask while using a circular saw.
- Unplug the circular saw wire before making adjustments. It's safer to unplug rather than turn off the circular saw.
- Ensure the blade and rip fence are locked in place before starting the ripping.
- Always hold the circular saw firmly before ripping.
