There's a few things you can do to prevent tear out: using a zero clearance board, making a scoring cut, and slowing down your cutting rate / using a different blade. Consider flipping your wood to have the best (or 'show') side facing down and the ugly (or 'hide') side facing up, that way any tearout will be on the less nice side of your wood.

Tearout occurs only on one side of your work piece, the side where the blade exits the cut, for circular saws this will be the side of your wood that is facing up when you cut. Tearout is the ragged edge cause after cutting wood, there's a few reasons why this happens and luckily a few ways to prevent it. You may have noticed when cutting wood that there's a ragged edge to your cuts, this is called tearout. Straight edges on your cuts are the hallmark of a pro. The extra setup may take a little longer than just eyeballing the cut. Be mindful when cutting that you want to set up your work so that any cuts fall away safely. Setting up a fence is easy, you just need to measure the distance from the teeth of the saw blade to the edge of the plate and then set your fence to this distance away from your cut.Д¬lamp the straight edge to either the wood or the workbench to ensure it doesn't move. A fence is a straight member used to guide the plate of the circular saw. You can make a cut without any guides by carefully following the line with your cut notch on your circular saw, but an easy way to get perfectly straight cuts it to set up a fence.

Secure your wood to a workbench or other stable surface with clamps. Measure and mark where you want to make a cut, remember to add a check mark on your line to determine which side you're cutting on. Of course, you can always use a mitre box with your handsaw to keep things nice and straight if the marking technique doesn't work for you.Д¬utting straight in plywood is a little easier, since the blade doesn't wander as much during a cut. This might not seem like a big deal, but when your entire project doesn't fit by 1/8' it can be very frustrating. If I cut directly on top of the marked line the kerf would eat into a small portion of the measurement. When marking I use a little check mark that tells me on which side to cut on, if I line the kerf up to the checked side of the line I know that the piece I cut will be exactly the right size. I start by using measuring the thickness of the wood, then measure back the same distance from the end, finishing by scribing a pencil line around the post with the square edge. In this video I want to make a cube from this 4'x4' post. Rotate the square and make corresponding lines along the sides of your cut line, these side cuts will help guide your cut to ensure that your blade isn't wandering off the cut line. To cut square (at a 90В° angle to the length of the wood) you'll need to make a square marking, align the edge of your square along an edge of the wood where you want to make a cut and draw a line with a pencil. Knowing this will help you plan for your projects and account for the actual dimensions you need, and what you should be shopping for when you pick up lumber.Д¬utting wood is easy, but takes a little skill to make sure your cuts are straight and square. This is true for lots of dimensioned lumber, so be aware and always double check the dimensions at the store before buying. To account for this the mills then process the wood through a plane to smooth down the surfaces and clean up the edges, ideally giving you a straight and smooth board, at the expense of some lumber dimension. Part of the reason is that when a tree is felled and chopped up into boards it has a lot of moisture still inside, when the wood is kiln dried it shrinks and warps after losing the moisture. However, if you take a tape measure to the wood you'll notice that it's not really 2' by 4' at all, it's about a ВЅ' shorter on both measurements giving you a 1-ВЅ' by 3-ВЅ'. We've all seen lumber dimensions in the home stores, like 2x4's, which is indicating the cross section dimension of the lumber - in this example 2' by 4'. It's not really a secret, as every carpenter knows this, but it's something you should be aware of before buying the wrong size for a project. The wood dimensions listed on lumber are a big fat lie.
