The Easiest Way to Cut Down Plywood Sheets

If you do a lot of woodworking–especially cabinets, built ins, or storage pieces–plywood quickly becomes your best friend. Sometimes breaking down a full sheet of ¾″ plywood can be a little….daunting. I’m showing you how to cut down plywood sheets easily and accurately so you can quickly move on to the fun stuff–the building.

I know you’ve noticed, I use A LOT of plywood around here. Plywood is a really nice material that makes building large furniture pieces clean, easy, and quick. I love using it.

.

But cutting it down isn’t exactly the highlight of my day. So I’ve figured out the easiest, most efficient way to cut down plywood sheets using a few simple guides.

.

No special tools required. An extra set of hands is always nice to help lift the sheet up onto the sawhorses, but not necessary if you use a little creative determination…and leverage.

How to Cut Down Plywood Sheets

To break down my plywood sheets, I use four things:

• Circular saw with Plywood Blade
• Kreg Rip Cut
• Kreg AccuCut
• Kreg Trak Horses (optional, but I really like them)

.

Now, you can totally use a table saw to cut down your plywood sheets. I have a really nice table saw, but I still prefer using a circular saw to cut my sheets down because trying to maneuver a heavy sheet of plywood through a table saw by myself is a struggle.

.

It’s much easier to cut it down with a circular saw, so that’s what I’m showing you. I’ve got a video here, step by step below, and some FAQ and tips at the end.

Step 1: Setting Up Plywood Cutting “Station”

In order to cut down plywood, it needs to be set up on something–like a workbench or saw horses. Or if you prefer to cut on the ground, that works, too. BUT, no matter where you choose to cut down your sheets, it needs to be sitting on some sacrificial scrap blocks.

.

This allows you to lower the blade of your circular saw so that it will cut THROUGH the plywood, but you won’t cut your workbench, sawhorses, or anything important.

.

Now, personally, I prefer to set up my Kreg Trak Horses to cut my plywood on. You can use any brand saw horse or even homemade saw horses. I just like these because they are easy to set up when I need them, and they fold away when I don’t.

.

.

I set my scrap 2×4 blocks on the top of my Trak Horses and set my plywood sheet in place.

.

.

Step 2: Setting Up Circular Saw

.

I keep two circular saws handy in my shop. I know that isn’t feasible for everyone, but it’s really cut down on change over time in my shop. So it’s something to consider for your own shop, especially if you cut a lot of plywood.

.

I keep one for general purpose use, and I keep the other set up specifically for cutting plywood.

.

.

But, if you only have one, when you get ready to cut plywood with your circular saw, make sure to install a plywood cutting blade. These blades typically have a high tooth count to help prevent tear-out for cleaner cuts.

.

.

Once the blade is installed, it’s time to add the Kreg cutting sled. I use a Kreg Rip Cut and a Kreg Accu-Cut to cut down my plywood sheets. This blue Kreg sled attaches to the circular saw to allow you to use it with these guides.

.

.

That said, attach the sled to the circular saw base according to the instructions and based on your particular style saw. The sled attaches using these two set screws. It’s important to make sure the sled is attached square on the saw base, and not crooked.

.

.

NOTE: It takes a few practice cuts and adjustments to get the sled set up with the Accu-Cut and Rip Cut the first time. I recommend setting the sled up with the Accu-Cut first, then the Rip Cut.

.

I set mine up so that I don’t have to adjust the sled when swapping between the two to keep things quick and accurate. That’s another reason I use one saw specifically for plywood…I never have to remove the sled once I got it dialed in and making accurate cuts.

.

Step 3: Ripping Plywood Sheets to Desired Widths

.

I know this is STEP 3, but you can cut down plywood in whatever order you wish. Typically, it’s easiest to rip the sheet lengthwise into the widths you want before cross cutting the lengths you want.

.

Speaking of, let’s discuss the difference in cross cuts vs rip cuts. Rip cuts go WITH the grain, cross cuts go ACROSS the grain. So it looks like this on a plywood sheet.

.

For ripping plywood sheets, I use my circular saw with my Kreg Rip Cut guide. This guide is designed to rip plywood into strips by running the straight edge along the edge of the plywood while the circular saw cuts a certain distance away.

.

.

I slide my circular saw with sled attached onto the guide and set the desired width, then flip the tab to clamp in place. Double check with a tape measure that the distance from the BLADE to the guide matches the width you want.

.

Also keep in mind that the blade CUT (or kerf), should be on the WASTE side of the piece.

.

.

Before cutting, I make sure my blade depth is set to cut SLIGHTLY (1/16 – ⅛″) deeper than my plywood sheet.

.

.

Then, I cut from one end of the sheet to the other keeping the straight edge nice and tight along the plywood edge. It’s important to keep it tight, but also square so that the blade cuts square. This should give you a plywood strip your desired width.

.

.

NOTE: If your plywood is moving while you are cutting, clamp it onto your saw horses where it won’t be in the way of your cutting.

.

Now, that’s how to easily RIP cut a plywood sheet, but what about cross cuts?

.

Step 4: Cross Cutting Plywood Sheets to Desired Length

.

Again, you could swap step 3 and 4, but I usually rip first, then cross cut second. My miter saw can cut up to 16″ wide boards at a time. If my plywood strips are smaller than 16″ wide, I like to use my miter saw (again, with a fine tooth blade, or it may cause a lot of tear out), to cut my pieces to the desired length.

.

BUT, if my pieces are wider than 16″, I use my Accu-Cut. This has been a really handy guide to have not just for cutting plywood, but for several other applications as well.

.

So I measure and mark the desired length I want to cut my plywood, and use a square to make a mark on each side like shown below.

.

NOTE: when cross cutting plywood with a circular saw, flip the good side over so that it’s on the bottom. Most tear out will occur on the top of the cut when using a circular saw, so whatever tear out you encounter should be on the “bad” side if you flip it upside down.

.

.

Now, it’s important to make sure you have a support underneath where this cut will be made. If you only support the ends, the piece will sag at the cut and pinch the blade.

.

This could be dangerous and cause kickback. I position my saw horses so that this cut is supported OR place a couple 2x4s across them like shown below.

.

Once everything is properly supported, it’s time to cut. The same sled I used with the Rip Cut fits with the Accu-Cut as well. When the Accu-Cut is properly set up, I simply line up the cut edge with the marks I made with my square earlier.

.

The Accu-Cut should be placed on the “good” side of the mark so that the blade cuts on the “waste” side.

.

.

Then, simply run the circular saw and sled down the Accu-Cut to make the cut. The rubber grips on the bottom of the Accu-Cut guide should hold it in place while you make your cut.

.

If you find it’s slipping, wipe the dust off the grips, and wipe the dust and debris off the plywood surface.

.

.

Step 5: Start Building

.

And that’s how I cut down my plywood sheets! It’s really that simple…set the sheet on scrap blocks on sawhorses, rip widths, cut lengths, start building.
