- Even experienced woodworkers get tripped up by these. Knowing how to position a wooden part for maximum strength and keeping wood movement in mind while working with solid wood will level up your woodworking game.

“Good timber does not grow with ease:
The stronger wind, the stronger trees;
The further sky, the greater length;
The more the storm, the more the strength.
By sun and cold, by rain and snow,
In trees and men good timbers grow.”
When you see people breaking boards with karate, you can guess which direction the grain is running in those boards.
Makes for hilarious videos when people don't pay attention to that (or, even better, try to "karate chop" plywood).
@@rjtumble as a child I tried to punch through wet melamine chipboard... my first ever broken bone.
John, you're legally required to say that "Wood is like a bundle of straws" in any video like this.
I was waiting...
I didn't want to date the video. In a few years, no one will know what a plastic straw is anymore.
@@IBuildItScrapBin Drinking straws were always waxed paper, before plastics became a cheaper or easier option. And now it’s going full circle.
I'm the opposite...i get skinnier in the summer and fatter in the winter. Plenty of expansion these days...
You should do an entire series of videos like this for beginners. It probably would get a lot of views. You could walk people through getting their first tools, doing their first simple projects, and getting comfortable with woodworking, just like 9th grade shop teachers have been doing for the past 100 years.
Thank you John for taking the time to explain the basics to all new woodworkers, I appreciate it.
John - great explainer on grain structure + expansion/contraction in wood and how these two weaknesses are made less impactful in plywood. Thank you for producing this and sharing it!
I have nothing to say really, but I appreciate your content, and wish to help with the yt-algorithms.

Coversation, talking points, exchange and the like.
Simple, basic but really important for biginners.
Great tips, John! Thanks a lot! 😊
I'm learning that, little by little.
Stay safe there with your family! 🖖😊
I cant believe it's taken you this long to explain what wood is, I've been watching for years utterly baffled as to what exactly you've been working with. :)
Great video. You should have more like this.
John looks like the computer nerd for sons of anarchy. Like he's just as tough as everybody else he just happens to handle the books.😂😂 I freakin love it.
I remember being mind blown when I first learned that the grain is a series of tubes/wicks that the tree uses to pull water and vitamins up from the dirt to the leaves then the sugar back throughout the tree to grow. This is why it swells because its designed to pull in water.
Good video!
lol... I knew you couldn't say that with a straighrt face😂
Basic knowledge opens the door to the world.
Don't think I've heard if explained better - thanks John.
Excellent
Really like these videos explaining fundamentals that I normally would not think about
Hi John, do you ever make wooden toys? You are giving off a Christmas vibe you know.
Wow John, this is THE(long e) best instructional videos I’ve ever seen on wood grain and orientation! I’ve always tried to explain this kind of thing to my kids and friends, but you have mastered the explanation in a way only a great teacher could do. Thank you very much for this video. I will share it with everyone that I think could use it! Besides, then I don’t have to struggle to do it myself....😆😆😆 I think maybe this warrants me becoming a Patreon!
Look at you, John, rockin' that longer-hair look. It's good! So is the video content. Good educational message. Thanks for sharing.
Thank you very much for your detailed explanation😀
Good talk. Toss in the term "non-isotropic material properties" for the big scrabble score.
For anyone who doesn't know, "isotropic" just means "same in every direction. Wood is "non-isotropic" because the properties are not the same in every direction. The more scientific word would be "anisotropic." If you want to get really technical, wood is an orthotropic material, meaning that in 3 perpendicular directions you can identify 3 different properties (grain direction, radial direction, and circumferential direction). Though typically as woodworkers we consider wood to be transversely isotropic, and often don't consider the difference in properties between the radial and circumferential directions, as they are relatively similar compared to the direction along the grain. Essentially that it has one property with the grain and another property perpendicular to the grain. If you start getting fussy about whether your wood is quarter sawn, plain sawn, or rift sawn, then you are starting to get into territory that you recognize the wood is not quite transversely isotropic.
Nice simple video John. Have you looked at some (most) mass produced furniture and thought 💭 no way these guys care which way the grain runs? I think you could have sold some moisture meters with a link in this vid.
Great video! Thanks so much! I have learned so much from your videos!
Thank you, from the bottom of the bell curve.
"Your wood is gonna shrink and your wood is gonna swell". Somebody set that to music.
2nd verse: "This is a problem you'll have to allow for especially if your parts are bigger."

Very good John. Sways good to cover the basics. Would be interested in your considerations for “food grade” woods. Can I make a pallet wood chopping board for example? What finishes to avoid etc etc. thank you as always for your knowledge and entertainment.
good job..good explanation'
Nice tutorial
When your wood really shrinks is when you were in the pool.
can u make 3D wood grains going in all 3 directions hahah something to think :D
i know a way it could be done but it's gonna be one hell of a messy glue-up!
That's basically what happens in knots and burls.
@@mrhumptydee plywood have 2 ways grain not 3. it was joke if u can make 3 ways grain wood its imposible all u get is headage:D
Wood is a state of mind my duuude
Thanks! .... but what will you do with so much plywood behind you?!?
I still have a hard time figuring out which way to run wood thru jointer and planer.
Look on the side of the board how the grain exits the face, it should exit the face to the back of the direction you are machining it in. In a flat-sawn board that means the top of the arc in the face grain is pointing backwards on the face that you are machining. It doesn't always hold true, but usually does. With quarter-sawn wood it often doesn't really matter while machining, but it could. When in doubt, try a few strokes with a hand plane, you will quickly feel which way it goes the smoothest. If the surface is already planed, you can often just run your hand over it to feel which way it goes the smoothest. You don't want to stroke the cat the wrong way, neither should a plane blade.
Knots and other changes in direction in the grain will always require some trial and error. Sharp blades mitigate a lot of problems, segmented cutter heads even more (they care a lot less about grain direction, but will still benefit from doing it properly.)
@@MrPanohead Wow! This was a decently compiled explanation!
Trees are vertical 3D printers. Well, wood is a lot like 3D prints. Weak in one direction, strong in the other. The young kids might understand that with today's technology.
strength axis is great description and common sense is not common among the untrained
What about burl wood?
A nice linkback to this video: youtu.be/watch?v=vjCRHsD0pkE
Covers LBL.
I've heard recently of cross grain plywood which has esch ply running in the same grain for wrapping curved areas.
An important lesson is the difference between the cellulose and lignin that form the grain. I've found building lumber to be difficult to chisel cleanly compared to a nice hardwood.
What are these, 'trees' of which you speak?
John, your hair is growing longer than normal...
Here comes the negging crowd, saying that you don't have to say something so obvious and primary, falling to remember that not everybody knows this important stuff yet.
Even the people that think they know the important stuff might not know the important stuff.
Anyone with common sense should surely know this
Common sense is becoming increasingly rare these days....
@@mrhumptydee hence the need for the video. I call it a Super power. Special Understanding of Perception in Everyday Rationalizations.
ok smarty pants show us how you are a good woodworker and weld the together lol
Ok Jennifer, but first please show us how to structure a sentence properly...just kidding...

It's called wood glue. Stronger than wood.
