@NinjaRider777R It may not have been your cable company. Most phones have been found to still be actively listening to you even when they are powered off. Have you ever noticed that if you power off your phone for a day or two that the battery's charge will appear to have been somewhat depleted despite the phone being off? Why would there be significant battery depletion if the phone is powered off and in theory not utilizing the battery's charge?

[@SW-zu7ve]

@@AntiNoob79 Its common knowledge that off isn't off. Its just what use to be sleep mode. If you didn't know it you do now. The only true off is unplugged and batteries out and even then you have to wait for the capacitors to drain. Nothing you have has a proper "power switch" that completely cuts the circuit from the power supply anymore.

Hey Matt, this is a wonderful video. You took the time for each "what happens when" scenario to explain each instance of what is going on. I really appreciate the effort and patience it took in order to put this video together and has helped me understand a fundamental of craftsmanship that has escaped me for some time.

[@MichaelScottPerkins]

Fantastic explanation! Been interested in wood working since I was watching New Yankee Workshop with my dad as a child, and I never could understand why one would need a jointer if they had a thickness planer. People would always say... one makes things flat, while the other just makes it thinner. I always thought... "Well, okay. But... how?" Now I understand perfectly! Of course! A planner just pinches the board in one narrow area as it pulls it through. A jointer lets the board ride more softly over spinning knives. So the jointer shaves off wood where the board is higher or lower. The thickness planner just shaves off X amount of wood, all along the board, maintaining the same warped profile... warped or flat. Thanks Matt! You really have no idea how awesome your explanation was.

[@mcremona]

Michael Perkins Thank you so much for the topic suggestion. This was much easier than trying to explain it by email too:)

[@MichaelScottPerkins]

Matthew Cremona Definitely! Keep it up man!

[@benjaminlane9228]

He was very right about the jointer being the "therapist", if you will, of the shop tools. You CAN get by without one, but the building process is much more enjoyable when you have one. For whatever reason it seems to be one of the later tools I see a lot of woodworkers purchase when in reality, it should be one of the first. Considering the vast majority of wood is in "rough" form (it's very expensive otherwise) it becomes important to "true" up one side as that becomes your reference. Any imperfections in that initial reference side will manifest as ANGER throughout the rest of the project.

[@Desolatedreamscreation]

i belive the main reason is the price they are expensive for a good one you can find a bench top one relatively cheap but when youre buying a tool that is essentially the heart of the shop you want something good. and for that reason i believe people get it later on myself included. theres a lot of things you can do on a table saw with the right sled

[@devogle7905]

Thanks Matt, best video I have ever seen on Jointer and Plainer. I have been woodworking for 20 plus years, learning through trial and error. Probably the first few years I made lots of mistakes trying to figure out my problems with Plainer. Then I bought myself a Jointer and you are absolutely right, what a joy to work with flat and square lumber. I have referenced your video to many of my fellow woodworker who are just beginning. Thanks again.

[@couchpotatoe3204]

My gawd you're a fantastic teacher.

[@spekenbonen72]

Sweet!. Watching this made me feel like being in school again. About the 2 planes of the jointer. They are parrallel. Few important notes: You only flaten and square 1 angle/corner on the jointer. (jointer -> planer -> table saw) You always check the grain of the wood. Just like a handplaner, you don't go across or against the grain. (Sometimes you have no choice though...) And you want the hollow side of the board (when cupped) on the jointer surface. Otherwise it won't get flat (and square). Subbed!

[@tacojesus]

This is the absolute best video I have found explaining this stuff. I am new to woodworking but not using tools in general, but the jointer/planer thing confused me and this video went above and beyond breaking everything down. I appreciate it.

[@vtrmcs]

There is something I'd like to add to Matthews excellent video. One of the key things when learning to use a jointer is understanding the sounds of the process. It's very difficult to explain in words, but sound tells you a heck of a lot. For example, if you're getting tear out as a result of reversing grain in a board, or because you're taking too much material in one pass, you can hear it. That also tells you if you're planing with the grain (correct) or against (almost always incorrect). When dealing with a board which is bowed, curved lengthways, as Matthew is in the video, the sound the planer makes will tell you if you're removing the bow or not. With a bowed board, you'll hear the planer knives engaging as the front portion of the board crosses the cutter block, it will then disengage for a time and the sound will change, before re-engaging the tail end, where the sound changes back again. If you had been applying too much pressure, then the sound would have remained consistent throughout. With practice, you can learn to match the sound with what the knives are actually cutting and where. If you really want to see the results and practice, you can spread chalk on the face of the timber being planed, then it's easy to see what material is being removed each pass. It's really quite cool to see. A little tip: Never apply pressure to the board directly above the cutter block. There is no situation where this is correct technique. Take light passes of less than 1mm a time, rarely is it a good idea to go above this if you want a decent finish. A jointer is a tool like any other and takes a lot of practice to use well. It's quite a dangerous tool so do triple check your setup and keep the blade guard in the right location. You really dont want a planer knife flying at you at 300 mph as you'll end up with no head, which isn't ideal.

[@paulreader1777]

Good additional comment. I actually noticed and noted the difference in the sound during Matt's demo. I'm learning heaps today.

[@l.clevelandmajor9931]

Excellent advice, my friend. What we woodworkers use to practice our trade is a large amount of very dangerous power tools. Jointer Planers, Table saws, Band Saws, Radial Arm Saws, Chop Saws, Router Tables, Sanders of various types, Wood Lathes, etc. are all very dangerous tools. Number one rule about learning to use any of them is learn all the safety rules first. Then learn how to operate it. Safety rules for each tool should include what each one is not to be used to do,the proper amount of clearance from the blades or abrasives of all your body parts, the purpose and proper use of all safety equipment that is needed for a particular tool, The proper conduct of other people that are in the work environment (like never do or say anything that can distract the tool operator from what he or she is doing). I've been in the woodworking business for 45 years, and I still have all of my fingers. This is because I always make safety the most important part of any job I do. I've seen first hand what not practicing safety can do.

[@ryszardjacekrusniak7993]

@@l.clevelandmajor9931 Right... AND the proper clothing when working with this machinery, rather tide than loose, no long hairs hanging down.

[@l.clevelandmajor9931]

@@ryszardjacekrusniak7993 Indeed, you are quite correct. Loose clothing and long hair not properly restrained can lead to serious injury or even death; not just in woodworking, but also in many other trades in which heavy power equipment is used. As the supervisor of a cabinet shop I once worked in, if any of my team were not adhering to even the tiniest safety rule, I'd reprimand them, on their first offense, on their second offense they were suspended without pay, and on their third offense I would terminate their employment with the company we worked for. No exceptions would be tolerated. As a result, my shop got the highest safety ratings in the company on a consistent basis.

I know this video is years old but I still want to put up a note of appreciation. 44 years ago I took high school wood shop from cranky old Ed Matilla. My dad was a finish carpenter and cabinet maker and Mr Matilla knew my dad. Cranky ol Matilla would never explain ANYTHING but he was darn good at screaming “You start with the jointer!” At the 2nd why, he threw a board. “Ask your dad” was the most I could get from him. Sorry Ed, my dad’s dying of cancer, we don’t talk much. All these years, I kinda knew but not really. Now I know because of you. All these guys want to give you crap about coplanar - I knew what you meant. And now I know what and why about a jointer, too. Thank you. You are a much better teacher than cranky old Ed Matilla ever was.

But you get a Jointer, planer, table saw Router, sliding table saw, Shaper all kinds of stuff in one machine. Buy each one of them tools separate its going to cost a lot this thing was 12k and takes up a lot less room. you can automatically eliminate 6 or 7 tools in your shop , that's a lot of floor space.

Hey Matthew. I'm really happy to see your video and wanted to say thank you. I've been taking woodwork courses for the past 4 months. Lately I've been surfing video to see if I could spot mistakes in their woodworking video and yours is (IMO) perfect. I really appreciate that you take time to explain everything and the why of it. My teacher did the same and now I'm starting to build furniture with high quality build. Jointer is the key to all this. Thx again for your, in detail, explanation.

[@PatrickPoet]

Did you know that in the UK a jointer is called a planer and a planer is called a thicknesser? The infeed and outfeed table of a jointer aren't coplanar, or in the _same plane,_ they form _parallel planes._ To be the same plane they'd have to be the same height. A jillion years ago we couldn't use any of the power tools in junior high (middle school), until we were able to make a board square on all sides and flat with hand tools. I think it might help people understand the power tools. We were kids and everybody got it pretty quickly, so it isn't that hard. The people that got it quicker helped the ones that struggled more. Sometimes another student might have a different way of explaining from the teacher that another kid might click with.

your welcome matt..after watching your video,i took a piece of claro walnut,to my friend,who has a jointer,and i asked him to run it over his machine,to take out the slight bow,in my wood.the first thing i noticed,was how hard he was pressing on the wood,as it went over the cutters..i mentioned that in your video,how you explained the correct way to do it,so when i asked him,to not put so much pressure downward,he said he has to do that because the wood was bouncing on the cutter as it went across..he said the wood is very hard,so that is why he does it that way...i asked him if maybe the cutter was sticking up too high,and if he could lower it,maybe it would not bounce so much,,he just kinda looked at me,and said,that he has been doing it the same way for years..anyway,i finally left,with the wood still not correct. i make small walnut ammo boxes,and if the box sides,and ends and corners are not parallel,square,and 90 degree's ,in other words,a perfect dimensionally correct box,it is a waste of time,to start drilling the holes,for the shells,in a box,that is out of wack...it was frustrating watch,to say the least..do you think it would of helped the wood to stop bouncing across the cutters,if they were lowered? it seemed like he was just taking off too much,with each pass..i think if he would of just done it,like you described,as far as just enough downward pressure to keep the wood on the table,and use more pushing motion to move the wood across the cutters...please let me know what you think,would of helped ...,,by the way,the piece of walnut is apprx 8-9 inches long,and apprx 2.5 inches thick...thanks again, i appreciate your videos..jb

Hey Matthew Cremona Love the vids and your work, dont have a jointer myself but looking into handtools. Just wanted to help out your definition at 4:00 about "Coplanar" (meaning in the exact same plane). I believe the 2 tables of a jointer are parallel but not coplanar. the difference is the few mm for blade (cutting) depth. Does that make sense? or am i off on how jointers work? Thanks for sharing so generously and love how you generous and humble you are. Thanks again!

+Majid Al Qassimi is correct. Further, many jointers use a parallelogram design to ensure the surface(s) remain parallel, but they are most definitely not co-planar.

Matt, it is good to see people your age who know how to work wood. I am third generation on my Pop's side of the family, and at least 5th generation on my Mom's side in woodworking. I have a nephew who is getting into the business now because of me. I'm pushing 62, and I don't ever want to stop doing this type of work! It is so satisfying to see pieces I turn out in my shop getting great compliments on the workmanship. But the real reason I do this work is because I love it. I can see that you do too, just from the way you talk about it!

[@echarters]

The jointer's outfeed and infeed beds are in parallel planes. This is true geometrically because planes have infinite extents. They are not the same plane. Minor grammatical quibble. Adjusting these beds to being "co planar" so to speak, or the two planes to be parallel is a nightmare as we know. It should be made easier. Good explanation of the difference between the two machines and developing the inferences we need in order to understand how to use the two machines. In fact the two planes of a jointer are NOT coplanar mathematically. I don't care if the company making them says so. I don't care if 10,000 expert woodworkers say they are. They are not mathematicians. The infeed and outfeed are (normally) in two distinct non intersecting planes. Coplanarity is a word. It just does not apply to jointers.

[@justinkinter8651]

Okay, beginner here, and I need a jointer now. Had no idea what these were used for, but I would always find myself thinking out loud, “I wish every piece of stock I purchased was just completely square and flat, it would save me sooooooooooooo much time, money, sweat, and tears” as I worked on a project, and now I have the answer.

Yeah I’d say parallel planes too. Two planes that are parallel but offset from one another. Same level would be the same plane and that’s not what he means here. To be fair, he did say co-planar which I would interpret as being on the same level but I think he used that incorrectly.

[@gerardvila4685]

@@link_7164 You're right. Parallel planes, not the same plane. Co-planar means "in the same plane" - it's most often used for a set of points, with more than 3 points - so the two tables of this thing are not co-planar (unless you adjust them to zero offset).

Mike 61 your probably gonna get the same response as i do every time i stop by lol

[@Mike-uj1wr]

***** Haha :)

[@jamesfulghum6189]

Holy crap. I have been waisting wood due to excessive pressure for many years now. Things video is gold for me. Thank you this information.

[@MRrwmac]

Coplanarity coercion of compatible woods for cohesive copulation to a single board.

[@mcremona]

MRrwmac oh wow. Nice one Mac!

[@soundboy89]

Awesome, I've been watching woodworking videos for months and this is the first time that I fully understand the workings and purpose of a jointer, thank you!

[@thecrazybushman]

Great as always!

[@carinotresvinos4342]

Mark, excellent explanation of what a jointer and planner does for us. Your explanation of how they work is something I needed. Thanks.

[@mcremona]

carino tresvinos Thank you!

[@vashon100]

4:12 planes are parallel, but not coplanar. There are not two planes, if they are coplanar.

[@nathanmorton9656]

Great educational video. I too was confused on the difference between the jointer and planer. This is an awesome example of how and why they both work. Thank you.

[@Jaze2022]

Co planarity... Lol. Parallel my friend. Parallel

[@JamesBonedOO7]

Jaze the tables are parallel and separated by the cut depth

[@crustyoldfart]

No - parallel refers to 2D space, coplanar refers to 3D. A line is defined by 2 points, and 3 non colinear points defines a plane.

[@JeffreyWigington]

@@crustyoldfart Planes can be referred to as parallel in 3D space as well. Co-linear means on the same line, just as co-planar means on the same plane. The "in-feed" and "out-feed" should not be co-planar or the jointer would not be effective. However it is critical that the in-feed and out-feed tables be absolutely parallel planes.

[@crustyoldfart]

@@JeffreyWigington You are of course absolutely correct to point this out. My comment came out not quite as originally intended. I was actually intending to amplify the comment by Jaze who in his turn was making a distinction between parallelism and coplanarity. My first point about a plane is that it is sufficiently defined by three non-colinear points. By extension two parallel planes require six points arranged in two sets. The six points can be determined by first choosing three points randomly, a fourth point is constrained to be not coplanar with the first three ; the fifth and sixth points points must be such that for each its perpendicular distance from the first plane is the same as that of the fourth point. While on the subject of planers we can further assert that the cutting head must revolve about an axis which lies in a third plane which is coplanar with the first two parallel planes. I'm sure that it would also be possible to extend the discussion beyond the axioms of Euclidean geometry by drawing attention to his parallel postulate, but I think that here would be a good place to stop ! ?

[@billtravis523]

I've been using a cabinet saw to help true up box store lumber for my infrequent and rudimentary projects. However, that only "sorta" works when one is searching for precision and it is not perfectly functional on the wide faces of lumber as my saw only cuts 3" deep on each pass. Clearly, it's time to step up my game and get a jointer! Now, on my second day of serious consideration of jointer vs. planer, I appreciated this video very much. A jointer wil also help a lot as I begin utilizing narrow siding boards from the 1920s barn I am reclaiming. I'm now a subscriber, Matt. Good job!

[@abiseid]

Matt... what a pleasure it was to watch your class. Crystal clear explanation and very enjoyable. I will be looking at your other videos.

[@mcremona]

Thank you so much Robert! I hope you like the others as well.

[@abiseid]

I am definitely going to look at all your other videos. I had a man cave built last year...36'x24', acid stained concrete, exposed tubular industrial ac venting. Very vintage because that is what I like. I am setting up all my wood working toys in there so can play. I want to learn from you and I really enjoyed your video and presentation. Straight forward, pleasant, natural and very informative... no fillers :-).

[@mcremona]

Thank you Robert! I hope you enjoy the other videos. Have fun playing in your shop :)

[@mcremona]

+BAdBrAd I bought it new from Grizzly

[@you5711]

Hi, Matthew. Thanks for giving us this great explanation. Is your Grizzly jointer model G0609X: www.grizzly.com/products/12-Jointer-w-Spiral-Cutterhead/G0609X

[@mcremona]

Yes

[@bobbg9041]

@@mcremona Nice Machine.

[@cbock35]

Incredible job explaining and very personable! This was awesome and thorough!

[@kevinitwaru5919]

I don't think they're the same plane, just on parallel planes, right?

[@alansimpson596]

Thank you Matthew. I'm a hobby wood worker and am just about to invest in my first ever planer so this video has given me a greater understanding of jointer/planer. Many thanks, Alan.

[@mcremona]

Awesome to hear! Thanks Alan!

[@ericmatthews3307]

When did Demetri Martin get his own woodworking show?

[@joshuamiller4108]

xD

[@thomascryer2380]

Thank you for the video!! Wish I would have found this sooner, I've been debating for a few months now on what to get first, planer or joiner! Just starting my woodworking career off, but on a limited budget so this helps not only to explain things but to give me direction. Thank you!!!

[@Visigoth_]

I Care!

[@mcremona]

Nathan Stoddard hahaha!! Thanks Nathan!

[@alfredosalinas3591]

Easy to understand explanation and the demo supports your observations... thanks, although I don’t have the tools I’d wondered about the difference and how these tools were different...

[@ophello]

They're not in the same plane. They're parallel.

[@deeeeeeps]

+ophello Yes, one table is lower than the other to remove material. The top of the blade is in Coplane with the outfeed table.

[@thenewfiejesus5530]

ophello who cares bruh

[@kobayashimaru8114]

Yea. He was struggling to find the words but he still explained what was happening correctly.

[@Zanmiester]

correct me if I'm wrong, but isn't the one just lower on the same plane? they're are both on X plane, for example, just because the one is lower, doesn't mean its on XY plane.

[@gnawlej9163]

Alexander B. If it's lower, then by definition it is a different plane. The tables of a jointer, unless they are set at the exact same height (which would be pointless), are on two separate but parallel planes.

[@mariomartinez4244]

This is by far the best how to video for a jointer. Well done.

[@chester82gtstang]

Just bought a table saw and realized the wood wasn't perfectly straight after cutting. The wife is not going to go for a jointer and planar. sigh...

[@ffuukkyootoobffuukkyootoob1411]

Hey. Great vid. I was trying to find out what a jointer is FOR, and you did an excellent job of explaining it. Thanks.

[@justinlynch6691]

Why demonstrate when ten thousand words will do.

[@MAGAMAN]

He did demonstrate. The ten thousand words were so that people understand exactly how and why it works the way it does. I've seen a lot of people pushing down very hard on Jointers in youtube videos. Just watching him do it, most people would not know that he was not pushing down hard on the board.

[@grandpasgaming5232]

MAGA MAN I am very happy he explained it the way he did!!

[@oceano_drive241]

LMAO 😂😂😂

[@slickfu]

Thank you! As personality profiles go I'm a "thinker" it helps me so much to understand the "why" and the "how."

[@mcremona]

Awesome! Thanks!

[@Loganb611]

i just pulled up this video to figure out what a jointer was, as I just recently heard of one for the first time, and expected to watch just a part of your video. Ended up watching the whole thing, paying more attention than I intended, and you earned another sub. Nice work.

[@mcremona]

Thank you Logan!

[@Gsauce08]

im from the Philippines and 18. i really learn alot from this videos. btw i am making cabinets and what nots with dovetails and so forth and this type of videos help alot in understanding my tools and what they can do. thanks alot!

[@AfricanSouthernCross]

EXCELLENT UPLOAD, ITS AMAZING TO THINK HOW MANY WEEKEND JOINERS, CARPENTERS AND FURNITURE MAKERS THERE ARE AND MOST DONT KNOW EXACTLY WHAT THE DIFFERENCE IS BETWEEN THE JOINTER AND PLANER.

[@mcremona]

thank you, Mark!

[@godbluffvdgg]

AWESOME presentation! Thanks so much...As a carpenter for 30 years, I've used a planer many times but never needed a jointer....I didn't do much cabinetry...I use mostly S4S stuff so it doesn't require much milling...But, you really made me want a jointer...:)

[@mcremona]

thank you!

[@maikay1403]

Matthew, that is one big and very nice jointer. Thank you for takes time making lesson video. I am new to wood working and jointer is the few purchase I really need to make. Have a wonderful day.

[@mcremona]

Thank you so much!
