Master Plywood: The Complete Guide to Clean Cuts, Hidden Edges, and Strong Joints
Plywood has been a woodworking game-changer since the table saw first started spinning. It's perfect for cabinets, furniture, and shop jigs—but it also brings enough frustration to make you question your life choices. Between tearout that looks like a beaver got loose in your shop and edges that show every cheap layer, plywood can humble even experienced woodworkers.
The good news? You don't need expensive equipment or years of experience to work with plywood like a pro. With the right techniques, you'll be building professional-looking projects while saving hundreds of dollars and avoiding the kind of frustration that makes you want to take up knitting instead.
Let's fix the biggest plywood problems once and for all.
Tools & Materials You'll Need
Essential Tools:
High tooth count blade – 60+ teeth for clean plywood cuts; slices instead of chews
Spiral down-cut router bits – Pushes fibers down to prevent tearout [AFF: Bits and Bits spiral downcut router bits]
Zero-clearance table saw insert – Supports wood fibers on both sides of the cut
Pilot hole/countersink bit set – Drills pilot holes and countersinks in one pass [AFF: Ammana countersink with depth stop]
Track saw or circular saw – For breaking down full sheets safely
Block plane – For trimming and flushing edge banding
Panel carrier – Makes moving 75-100 lb sheets manageable [AFF: Gorilla Gripper]
Materials:
Iron-on edge banding – Heat-activated veneer tape in rolls
Hardwood strips – Cherry, oak, or maple for solid wood edge banding
Wood glue – For joints AND sealing edges before paint
Foam insulation board – Creates sacrificial cutting surface on shop floor
Painter's tape – Optional tearout prevention (if you have infinite patience)
Pro tip: That "3/4-inch" plywood you just bought? It's lying to you. It's actually undersized, which is why your dado joints never fit right. More on that nightmare later.
Problem #1: Preventing Plywood Tear-Out
Tear-out happens when wood fibers splinter and stand up during cutting, making your plywood look like it got in a fight with a porcupine. It's especially ugly on plywood because you can see the second veneer layer underneath. Some people swear by the painter's tape method (1:01), but let's be honest—ain't nobody got time to tape every single cut line. You'll either forget or spend half your shop time applying tape like you're wrapping a gift.
Instead, let's use methods that are actually sustainable for real-world woodworking.
Step 1: Install the Right Blade
Your ripping blade or combination blade is chewing through plywood like it's trying to win a hot-dog eating contest. Replace it with a high tooth count blade—the kind that slices through wood fibers instead of demolishing them.
What to use: 60+ tooth blade designed for crosscutting and plywood
Step 2: Position Your Good Face Correctly
The direction your blade rotates determines which side gets tearout:
Circular saw or track saw: Good face DOWN. The blade cuts upward into the material.
Table saw: Good face UP. The blade cuts downward through the material.
Think of it this way: you want the blade entering from your good side, not exiting through it like a wrecking ball.
Step 3: Add Support for Both Sides
Want tearout-free cuts on BOTH faces? You need to support the wood fibers where the blade exits:
Track saw users: The track provides support on one side automatically
Table saw users: Install a zero-clearance insert to support fibers on both sides of the blade
A zero-clearance insert is basically a tight-fitting throat plate that hugs your blade, preventing fibers from breaking away during the cut.
Step 4: Choose the Right Router Bit for Edges
When routing plywood edges, straight bits and spiral up-cut bits pull fibers upward, creating a jagged mess. Switch to a spiral down-cut router bit [AFF: Bits and Bits spiral downcut bits] that pushes fibers back into the plywood as it cuts (use discount code for 10% off).

Problem #2: Hiding Those Ugly Plywood Edges
The faces of quality plywood can look stunning. The edges? They look like a geology experiment gone wrong—full of voids, odd-colored layers, and cheap filler material. Unless you're building geometric art projects, these edges need to disappear.
Method 1: Iron-On Edge Banding (4:19)
This is the "fast food" solution—quick, easy, and gets the job done.
Steps:
Cut your plywood to final dimensions first
Cut edge banding slightly longer than needed from the roll
Position the banding over the edge (glue side down)
Apply heat with a clothes iron, moving steadily along the edge
Press firmly as the adhesive melts and bonds
Trim excess with a specialty edge banding trimmer OR make a few swipes with a block plane
This method mimics what industrial shops do, except they have fancy machines that don't require you to dig out your clothes iron.
Method 2: Solid Wood Edge Banding (4:53)
This is my personal favorite and what professionals use for high-end work. It looks dramatically better than veneer tape and adds serious strength and damage protection.
Steps:
Cut thin strips of hardwood (cherry, oak, maple) to width [VERIFY: exact thickness not specified]
Apply wood glue to the plywood edge
Clamp the hardwood strip firmly and let dry
Once dry, flush the edge using:
A router with bearing-guided flush trim bit, OR
A hand plane for a quieter, more meditative experience
Bonus: These solid wood edges make your drawers significantly stronger—you're reinforcing with hardwood instead of relying on thin sheet goods alone.

The Paint Prep Secret (6:13)
If you're painting your project, here's a trick that'll save you hours and multiple coats of paint: spread wood glue on the edges BEFORE painting.
Why it works: Plywood end grain is absorbent like a sponge. Without sealing, the different plies keep drinking paint, leaving visible grain lines even after 4-5 coats. The glue fills those tiny voids and wood pores, creating a sealed surface that takes paint evenly in just 1-2 coats.
Steps:
Apply a thin layer of wood glue to all exposed plywood edges
Let dry completely
Sand lightly if needed
Paint as normal—enjoy single-coat coverage

Problem #3: Joining Plywood Without Splitting (6:53)
Plywood's layered construction gives it excellent screw-holding power through the faces (7:08). But drive a screw through the edge? You've just created a wedge that'll split those layers apart like you're splitting firewood (7:11-7:20).
Step 1: Always Drill Pilot Holes for Edge Screws (7:27)
Pilot hole sizing: The bit should match the screw's shaft diameter but be smaller than the threads so they can still grip.
You can use a regular drill bit, but I prefer combination pilot/countersink bits [AFF: Ammana countersink with depth stop] that drill the pilot hole and countersink in one shot. The fancy ones even have built-in depth stops for perfectly consistent results (8:01-8:07).
Step 2: Don't Skip the Glue (8:09)
Here's the uncomfortable truth: screws in plywood edges are pretty wimpy. You cannot rely on screws alone—the holding power in that direction is genuinely weak (8:17-8:19).
Always apply wood glue to the joint before driving screws. The glue does the real work; the screws just hold things while the glue dries.
Problem #4: Cutting Perfect-Fitting Dados (8:26)
A dado is a groove cut into one piece that holds another piece at 90 degrees—perfect for cabinet shelves and bookcase construction (8:30-8:42). Add glue, and you don't even need screws. The problem? Getting a snug fit instead of a sloppy, loose joint.
The 3/4-Inch Lie (9:09)
Pop quiz: How thick is 3/4-inch plywood?If you answered "3/4 inch," you're wrong. It's actually undersized—typically closer to [VERIFY: exact measurement not given in transcript]. This is why setting up a 3/4-inch dado stack on your table saw creates loose, disappointing joints (8:58-9:02).
You could spend your afternoon shimming a dado stack through trial and error, making test cut after test cut while your patience evaporates (9:32-9:46). Or...
The Smart Solution: Plywood Dado Router Bits (9:49)
These specialized router bits are undersized to match actual plywood thickness, giving you perfect-fitting dados without the hassle. I use spiral down-cut versions [AFF: Bits and Bits plywood dado bits] because:The downward spiral pushes wood fibers down (preventing tearout, just like we discussed earlier at 10:12-10:14)
The spiral cutting action slices easier and produces less heat (10:17-10:21)
No burning like you'd get with straight bits (10:21-10:23)

Bonus: Handling Full Sheets Safely (10:38)
Let's talk about the elephant in the room: full sheets of plywood are heavy, awkward, and have no good hand-holds. A 3/4-inch plywood sheet weighs about 75 pounds (10:50-10:53). MDF is even worse at nearly 100 pounds per sheet (10:53-10:57).
If you're working alone (and let's face it, most of us are), here's the safer approach:
Use a panel carrier like a Gorilla Gripper [AFF: Gorilla Gripper] to move sheets around (11:14-11:16)
Don't wrestle sheets onto your table saw—you'll throw your back out (11:18-11:20)
Break down on the floor instead: Lay sheets on foam insulation board (11:23-11:24)
Use a track saw to cut manageable pieces that you can then take to the table saw (11:26-11:29)
Your back will thank you tomorrow when you can actually return to the shop instead of lying on a heating pad questioning your life choices (11:31-11:37).
Choosing Quality Plywood (11:41)
Not all plywood is created equal—even sheets from the same stack vary wildly.
Never buy the top or bottom sheet from a stack (11:56-12:00). The top sheet has been exposed to sun and rain during transport, making it prone to warping (12:03-12:07). Both top and bottom sheets get damaged by the shipping bands that hold the stack together on pallets (12:11-12:17). Leave those sheets for someone boarding up windows.
Know your plywood types:
Hardwood plywood (oak, maple, birch): Denser, stronger, more stable—use for furniture and cabinets (12:25-12:31)
Softwood plywood (pine, fir): Better for construction, framing, and subflooring (12:32-12:39)
Ply count matters: More internal layers equal more strength and stability (12:49-12:54). A birch sheet from Home Depot might have 5-7 internal layers (12:56-13:02). True Baltic birch has about 13 layers and looks completely different (13:04-13:11). The difference is dramatic—Baltic birch is what the pros use when they need maximum stability.
The Bottom Line
Working with plywood doesn't have to mean accepting tearout, ugly edges, and loose joints. With the right blade, proper cutting technique, and plywood-specific router bits, you can achieve professional results without professional equipment costs.
Remember: use high tooth count blades, cut with your good face in the right direction, seal edges before painting, always drill pilot holes for edge screws, and invest in plywood dado router bits that match actual dimensions.
Now get out there and build something. Your plywood is waiting, and with these techniques, it's going to look fantastic—no beaver damage required.
