Great revision, calm, good sense. Educational, clear and a breath of fresh air vs the excitable lunatics in some other woodwork KZfaq channels

I have heard this wood grain lesson explained over a dozen times, but this is hands down the clearest! Kudos.

They say don't meet your heroes. Only ever wanted to meet a couple musicians, a couple folks in the world of pugilistic arts, and you my brother. Walking badass you are James. I appreciate you.

Like all your videos, this was incredible. I’ve been a novice wood worker for years and never felt like I understood wood movement very well until now. Thank you!

I’m a seasoned uk carpenter and this channel blows me away constantly!! Awesome content brother 👍👍

This should be seen and remembered by all woodworkers.

Excellent video. Thank you. This is honest and refreshing!

I have heard and read many explanations of wood movement, but having it so eloquently and concisely stated here was really useful and worth watching-- thanks!

That was the best explanation on wood warpage I've seen. Really enjoy your videos. Keep up the good work.

Best video on the explanation of wood movement I have ever seen on KZfaq!

Great video! It is packed with high quality, useful information. Thank you.

Thank You Sir, for that information and insight. It actually helped answer a few questions I've had for awhile now that will help me sort through wood for projects in the future.

An excellent tutorial! Good, clear, and concise explanatation. Thanks.

Thanks. It has been over 40 years since I had woodshop and I have forgotten allot. That really helps.

Great video and great information, thanks!

Fantastic advice most of us need to hear again, and again as it is easy to take wood for granted and get surprised the next morning! Another Great video, thanks.

Wonderful video and great explanation. Many thanks James!

Excellent informative presentation - well done James - many thanks

This is great info for newbies and oldies alike. It's a better explanation than anything else I've ever seen. Thanks!

Great video thank you for all your tips they really come in handy for someone like me who is self-taught and taught from other KZfaq videos

Well presented. Always enjoy your videos

Excellent explanations Stumpy! Great job...

Thank you James. This has been so helpful to me. All these years I was thinking that the crooked boards and twisted boards were due to the lumber yards cutting them imperfectly and selling them that way trying not to waste wood. I guess I didn't consider the issue carefully enough to research warping. But now I've gotten some deeper insight about wood. I guess I've known more about the tools I have used than the object on which they are used. I've never seen anyone teach about how moisture and temperature affects wood to the degree that you have in this video. This is so interesting. Again, thank you. Great job!

Excellent content. It explained so much , very simply without dragging out through a long video. Subscribed

Super articulate! I've been having a hard time understanding this concept as a new woodworker, but this helped me a lot! Keep up the good work! (And I subbed a while back ;D)

Great lesson. Very thorough. Thanks for sharing.

Thank you, that was excellent! I'm new to woodworking and I've been having a frustrating time with movement in a small oak table top. Now I have a much better understanding of what's going on. Really great, informative video.

Fantastic video! I am new to woodworking and have seen some of my straight pieces become warped and twisted and after watching your video I can almost remember everything I did that might have led to that happening now. Thank you for the great explanations!

i have received 2 orders of boards from Baird Brothers and didnt realize why they covered the stock in wrap. NOW i know......how smart was that of them to do such a thing?. Never saw this before.......thanks again for an excellent tutorial.

Excellent advices, out of the box subject.Thank you.

Very useful! It’s always good to understand, why that stuff happens, not just that it does! 👍

I learnt a lot from this video. Very clear and concise and a definite help with my future projects.

“Common sense” lol. You are such an expert. I don’t even consider myself a beginner, yet I always learn something from your videos. I really appreciate the knowledge, experience, and information you share. Thank you! As I’m upgrading and reorganizing my shop I do my best to support your sponsors.

Thanks for the great video James!

I like the straight and direct manner of performance. 👍

Thank you so much for this information...It is VERY helpful...

Excellent explanation of wood movement.

Excellent class instruction from the University of Stumpy Numbs. I needed to take a refresher course. Thanks!

Fascinating and useful. Thanks!

Seen number of your videos. Excellent!!! Thank you

Great information as always!!!!!

Great Info as usual James. Thanks

Wow, amazing, incredibly detailed video! Great job man!

Been watching your videos and they always has good info! I'm a subscriber now.

Very interesting. Nice video James!

Thanks. First time this novice understood the big picture on wood movement. Please keep up the great videos.

So much information here and it's all relevant to making informed decisions when sourcing timber. Of course, I'm going to make some poor choices when I purchase wood but it's going to lessen the those bad choices, thanks to you. Thank You! Allan

Excellent info. Thanks!

That's some gold! Love your theory sections, helps a ton to understand what's going on

Very well done sir!

cannot thank you enough for your educational material!!! thank you!!! 🙏🏽🙏🏽🙏🏽😊

great video, as usual. Thanks!

Very good information amigo

great advice James

Love this, great job!

Great job Stumpy!

Very well explained !!! Thanks !

great video and solid advice.

Excellent info, thanks

Excellent. Even I can understand this. Thank you!

Best explanation I got, thank you!

Thank you, very good instruction.

Very helpful. Thanks

this man right here is the wood wizard! iv read lots of information that quarter sawn is better but never heard an explanation why.

Great Video, thank you for sharing

Great stuff.Thanks. Amazing tool seection in the background. :-)

Excellent video!!

Good stuff Very informative

i subbed after seeing this video just found this channel this week.

Excellent content!

This was a very informative video. I was a little surprised that I didn't understand some of this stuff as well as I thought I did. Thank you. On another topic: dislike like ratios. Wow, as I watch this the don't like ratio was about .3%, that is really small from what I've seen. I'm not sure I've ever noticed a video with over a 1000 likes and only three dislikes.

thanks, helpful. I think I know why my last glued up table top panel cupped now....

Great video! Now set to install stair treads properly.

Well ain't that something. Everything I was taught about board movement, cupping, selection and arrangement... Was wrong. Thank you for this.

Using this in class with my H.S. students for sure!

Great video. Less than 1 minute then into it.Thanks.

#1 Cause of break downs in bro-friendships: Which way you should turn the growth rings on a board to prevent cupping when laying decking.

Excellent, thanks...

great video

Great thanks so much!

Stumpy Nubs ! Ha that is the best channel name i've ever seen

I noticed that your diagram shows cupping following the rings when it is actually the opposite side cupping upwards. Now that you have explained it so simply it makes sense to me why that is. Thank you.

Great content

Nice explaining bro. Danny from holland

awesome video

Once you hear that cricket, it doesn't go away. But real talk, great video. Thanks for making this.

One other item. Not all of the lumber you buy is KD. A moisture meter is a nice addition to the shop to give you an idea whether that board you purchased on the Internet is 20 percent MC or a much more workable 8 percent.

I once grabbed a perfectly flat, but bowed board from which I wanted to cut a narrower strip. Thinking that it wold be easier to simple put two string lines along it rather than mark a curved line from one edge, I did that and ripped the narrower board out. It immediately bowed in the opposite direction.

Great Information. When I cut my wood slats for a wood flag I end up with a few slats that are crooked (don't know why), causing me to not use that wood or if the crook is not too bad to clamp the slats together tight that results in uneven surface, any suggestion on this issue? Thanks.

Building a deck with 3 metre = 12' length 50x150mm = 2x6" treated pine joists back in "96 or so I sighted them lengthways and put the outside of any curve they had to the top because I looked it up. Was good advice as 22 years later it's still flat, but was that precaution related to warping, or just load under gravity?

Thank you,...great channel. Q? If my boards are slightly bowed, would it be best to secure these on my picnic table as the top, with the bowed surface arc up, in other words, the center being higher, and just screw them down, or both ends being up and screw them down? I can't remove the bowing, and its slight but the natural tendency will continue or at least be controlled by securing them. thank you for any feedback.

Great info1

Hey James, i need some advice and direction. I have a 10' X 3' table top. It is made of 2" x 10" x 10' long Douglas fir . The 10' planks shrunk big time away from the 3' x 2" end piece. I have pictures if you don't mind me sending them to you. I am hoping to remedy this but i may have to build another table from scratch.

Hey. I'm new to milling and I noticed your video here. I just bought a chainsaw mill and plan on milling 2 western larches I fell a couple days ago in a kind've remote area to build a 12 x20 cabin. I've hiked a lot of materials out with a sled (not a snowmobile) including 16 cinder blocks for the foundation of my air drying platform. I've dug out a 4' x 20 rectangle and leveled the cinder blocks but I'm worried that they might shift over time. What would be your thoughts and do you have any advise?. Thanks

Great Video!!! I am new to woodworking and currently hanging 1 x 10 knotty pine (assumig it is flatsawn) shiplap acclimated with stickers for at least three days, mostly longer on my shop walls. I learned alot from youtube video's about how to do this and one thing i saw in another video was someone making kerf cuts on the back of the boards to prevent cupping. I may have taken this to literately and began right away cutting length wise kerf cuts into all the back of my boards, about five passes. I think i may have actually caused some cupping from doing this because of my lack of knowledge about how to read the lumber. So , as a rule of thumb , when should i do this and when should i not. I am not finishing either side of the boards as it in my shop and i rather like the smell of the wood. The back of the boards is up against faced insulation and the building is heated and air conditioned in the northeast. Sorry if you may have answered this already in the video and i missed it , i will be looking at it again or more as needed but wanted to get this question to you. Many Thanks

I bought a house thst the outside is wood. Outside of my sunroom I see a few pieces of wood cupping how can I fix this?

Thanks dood

If woodworking doesn't pan out for James, he has a future in textbook diagram illustration for sure!

HELP! -- I am working on a Live Edge vanity 22 x 72 thickness of 1.5. This is my first ever project dealing with live edge. I was able to find a nice cotton wood slab 3in thickness, and had it planned to 1.5. I bring it home and had it lay flat for 7 days, now I have noticed "twisting" and minor "cupping". So I immediately tried to minimize it by clamping down to my bench top in the hope of straitening it out. I live in Michigan and it is hot and humid in June. Can someone advise me on following: (1) What to do now till I complete the finishing of the slab to bring it back from all twists and cupping - do I need to wrap it in plastic? (2) More Importantly: What should I do to minimize the twisting and cupping on the final product - how should I reinforce it? I appreciate your input and your video is helpful.
