Replace the 24-tooth blade that came with the saw with a 50- to 60-tooth blade for cleaner crosscuts in solid wood, veneered plywood, and other sheet goods. Because a circular-saw blade cuts on an upward rotation, the bottom face, in which the teeth enter the cut, will almost always have a clean, tear-out-free surface. “A custom edge guide for your saw not only beats tear-out, but also makes it easy to align cuts. Start by building a jig based on the drawing below; adjust the width as needed for your saw. We made ours long enough for crosscuts in 4′-wide sheet goods. Make the base’s cutting side about 1⁄2” wider than the distance between your saw’s blade and the footplate edge below the motor.

How do you use a circular saw without a table?
Fit your circular saw with an edge guide. Set the depth of the blade accurately enough for it to go through the wood and not cut under the surface. Place the guide on base of the circular saw lines and markings you made earlier on the wood. Ensure that the saw is free to move, and the power cord is not entangled.
How shallow can a circular saw cut?
Circular saws turn corners about as well as a freight train, and standard models will cut only about 2 1/2 inches deep. There are ways around the shallow cut—for example, you can flip over a 4×4 and cut from two sides—but the curve limitation has no work-arounds.
Which side should the blade be on a circular saw?
For blade-right models, the correct circular saw blade direction is usually with the label side out. For saws that have the blade on the left, it typically installs with the “ugly” side out.
Why does my circular saw kickback?
Overheating a saw blade can cause it to warp and result in a kickback. Buildup of sap on the blades, insufficient set, dullness and unguided cuts, can all cause an overheated blade and kickback. Never set a blade deeper than is required to cut the work piece 1/8 in. to 1/4 in.
How do you cut straight with a circular saw without a guide?
To ensure a straight cut, press the saw firmly against the straightedge as you push it along. Clamp a perfectly straight board or metal straightedge to a sheet of plywood to make cabinet-quality straight cuts.
Why is my circular saw burning the wood?
Pushing the stock through the saw too slowly is a common cause of saw blade burn. Sometimes a blade that feels dull might only be dirty. If wood pitch resins build up behind the teeth of the blade, the cutting speed will slow down, increasing the chances for burns. Commercial blade cleaners are sold for this purpose.
Can a circular saw cut a 4×4?
Circular Saw. A circular saw is one of the best means of cutting a 4×4 post. Most people own a circular saw, its portability makes it easy to cut 4x4s from the ground, and they can make precision cuts by using a relatively simple trick.
What size circular saw Do I need to cut 2×4?
You need a minimum 5-3/8 inch size circular saw blade to cut a 2X4 at a 90 degree angle in one cut which is a crosscut. If you want to cut a 45 degree bevel with this size circular saw it will take 2 cuts. You could go with a 7-1/4inch or 10 inch blade to avoid making multiple cuts with the 45 degree bevel angle.
Which cut is when you cut a straight 90 degree across the grain?
A crosscut is a straight, 90-degree cut that cuts across the grain of the wood. Usually, that means turning long boards into shorter ones. On a table saw, you will usually use a miter gauge to make crosscuts. It’s the most basic cut you can make.
Why are my circular saw cuts curves?
A faulty circular saw is likely to have issues such as an unstable blade or a warped blade edge. The problem could also be the way you operate the saw. If you do not operate the circular saw properly, it will not cut straight. Let’s discuss several causes why your circular saw might not cut straight.
What PPE should you wear when using a circular saw?

Do I need a workbench to use a circular saw?
To get the most out of your saw, you’ll need a couple of pieces of equipment. For a start, we recommend a good work table or bench for supporting your material. There’s other ways of brace wood for cutting, but a workbench is by far the simplest and most straight forward method.
