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!
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...:)
That's interesting. I was wondering about that as well, because I've only seen a jointer being used to straighten lumber on the rib side and planer - on the flat side, and so naturally, I thought that's what they're for.
Coplaner means they're in the same plane but joyner table beds are not coplanar unless you adjust them to be so otherwise when you're making a cut they will be parallel not coplanar.
Ahh...I get it now! Finally. Couldn't figure out why you can't just make a straight edge on the planer or why you can't just flip the board over on a jointer...and now I know. I do believe that the vast majority of people who watch youtube videos are doing so for "information or entertainment" and the vast majority of people putting out woodworking videos are so advanced in their skills that the information given is taken in more for entertainment than actual usable information. Point is...keep pointing out some very basic videos like this and you will be leaps and bounds above your competition who is often times much more interested in showing their vast superior knowledge (nothing wrong with this...but not necessarily useful to the masses). Anyway, great job in the explantation and it has helped me understand a very basic concept. Much appreciated.
👍Good stuff Matt. These machines have made it so much easier for a craftsman but not without its horror. I hope you don’t mind the following story. If it’s removed, I understand and all apologies. ✌️ *WARNING, GRAPHIC- /My uncle was a 16 yr old junior in High Sch wood shop class, running boards thru the jointer when his hand slipped & went into the operating knives. I’m sure You can imagine the outcome of his hand. The one day LACK of safety changed his whole life. During his recovery he quit school & has never been the same. Almost a recluse his entire life. Never married, no kids, never a love interest as far as I knew. This was in the early 70’s. Sadly, Not a lot of mental health help back then. He’s now 60, has always been VERY self-conscious of the lack of fingers & many scars. I’m sure it’d be horribly tough to deal with such a life altering blow! Its my opinion, his most troubling scar is within his own heart & mind. Such a shame as he never let it go. My family has always given him our support but he never wanted any of it & chose his own paths. He’s always held a job but always a job in the shadows if you will. I’ve often thought of this horror story while working w/ these machines & i believe it somehow kept me safe. I’m not mentioning this happening for any reason other than to stress PROPER SAFETY. Hope everyone’s projects go well and sorry if I over stepped here 👍 Thx Matt for the lesson. ✌️
6:45] You've also turned the board upside down, the cup should always face *up,* or down? resting on two edges, hump up?- you should mention that soon.
Matt, what if 2 boards that you ran through the jointer and the planer come out to different thicknesses. It would seem like something that would occur if the boards had different levels of warp and twist. And if that happens, when you join them together, the boards wouldn't be flush would they? How does one account for this?
if you want a desired thickness you will need about 1/4 extra thickness stock to achive final thickness..if you want 3/4 you need 4/4 board, if you want 1" you need 5/4 board, if you want 1 1/4 you need 6/4 board and so and and so forth..
I wonder if I had a 12" jointer if I could use it to flatten a 24" wide board by removing the guard and running it through again with the other side against the fence.
Matt, I think the term you were looking for was actually parallel planes, not coplanar. Coplanar would require the infeed and outfeed to be at the exact same level.
well here i was matt ready for a video, very good topic and you covered it very well, i really do like how you change your shirt for different parts of the video, keeps me on my feet matt...and on another topic...the pancakes over the weekend were fantastic, i found some good syrup ..:)>
Robert Putman Glad to hear I was able to keep you on your feet, Bob! Just finished mine. Late breakfast today, been working on getting this video out. Delicious as always :)
I'm here because 24 hours ago I had a 30 second conversation about a jointer with my phone in my shirt pocket. Surprise surprise, it appeared in my suggested videos.
@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?
@@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.
This is probably the most thorough tutorial I've seen on using a jointer... not only did you discuss what it does but you also discussed the biggest question in most people's mind about the relationship of planers to jointers. And to top it all you included proper technique. A+
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.
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
Matt. I really enjoyed your video on the Jointer. It was very well presented and easy to follow. Your explanations were well thought out, and very informative. I am in the process of building my dream shop on paper and a Jointer will most certainly be on my list of wood working machines to have in my shop. Looking forward to watching more of your videos and increasing my knowledge about wood working. Respectfully Maurice Pettiford Budapest Hungary.
I was looking at the Hammer by Felder and if I had it to start all over I'd consider a machine like that the only think it wont do is butter my toast. 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. You can use for other stuff.
"Hey wife . . . I was just watching this youtube video and it looks like I'm gonna need to buy another tool. It'll probably cost about a month's worth of income, but it will make nice smooth boards. Just saying." "Hey hubbie . . . yer gonna have to deal with crooked projects. Just saying."
Nah find a used one on craigslist. Jointers are the treadmill of tools. People buy them, and then the wife says she wants to [gasp] "park a car in the garage".
Before today, and getting here from the Jamie Perkins accident, I didn't even know a jointer existed. But I enjoyed this video so much I subscribed. This guy is so natural I just gotta see what else he's got.
Great video. I recently bought a jointer and had a hard time getting the boards flat. But now I know it's because I was applying too much pressure. Thank you!
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.
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.
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.
@@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).
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
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.
Why don’t boards just come planed and jointed? I can’t imagine a project where you’d WANT a board that’s bowed or twisted. I understand wood bends and warps in transit, but as tools like these aren’t reasonable to have in a standard home workshop you’d think at least they’d offer it as a service at Home Depot or Lowe’s.
Mostly happens during the curing process. The moisture content varies drastically at places like homedepot. Next time your getting lumber take a second and you will notice the weight difference in a bundle of boards
@@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.
@@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 ! ?
@738polarbear Not so great explanation when he's talking nonsense and also showing with his hands @ 4:15 about the cut depth being determined by the infeed table set lower (on a different plane) that the outfeed table, which is impossible for coplanar tables ! @Joe Ciccone is right in his comment @ 4:18 he also totally shows parallel planes not coplanar .
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.
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 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.
Another thing is if you don't use a jointer on a warped board,then send it through a non shop planer you'll get significantly more board snipe on the ends,from Hercules to Dewalt the small ones don't have the ability to hold the majority of the board flat so it will lift on and off of the ends as they pass through
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!
You answered my question about using a hand plane first and then running it through the planner so heres my question-does it have to be a #4 or could i use a#5 jack plane?which wood be more sufficien? I just picked up a Stanley # 5 Jack from rockler other day. I have yet to use it .needs to be sharpened. But as always great informative vid. Looking forward to the next vid..have agood one matt!
This isn't news for me but i wish i had this to watch when it was! You did an excellent job, the two glue ups especially tells the tale! I actually ran that experiment many times when i was starting out!!!! lol
Very good, clear explanation. The micro camera placed inside the machines was a great idea. Despite seeing several other vids that attempted to explain jointers, now for the first time, I understand how they work.
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.
You can watch this video or you could've simply time traVEL to public school in Michigan in 1976. Where students aged 12-18 went to Wood Shop Class to learn such remedial things..
Wisconsin, 1991, had a wood shop, a nice one, a machine shop, a basic one that prepared you to enter the 1940's shop running in the 1960's, and an auto shop that was ok if you were interested in learning. Not sure if ANY of that still exists. Up until two years ago there were machining jobs open all over southern WI for ten straight years.
Matthew Cremona Hi Matt, very good video! I have a solution to Dema's comment. You send me the jointer you showed in the video and that will free up space in your shop for a much bigger one. :) lol
You'd think it would be the other way around. That a planer would make a perfectly flat plane, and a jointer would make a parallel surface that could be easily joined.
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.
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.
I always love your videos, i like how much detail you go into. I do have a question if you dont mind. I just got my first jointer and im having trouble flattening stock on it. I just some set up and put some cuts through on a piece of already fairly flat pine and the test piece came out perfectly flat after only minor tweaking. I then tried to flatten some pretty warped walnut (rough sawn, twisted, bowed and cupped) about as rough as it gets. And i just cant get them flat. they're tapered width-wise and still rock back and forth. Some of them are worse even-having a convex hump length-wise. What am I doing wrong? and how can I recover these boards?
this was a super informative video,on why to use a jointer,and planer..in the proper sequance,etc..very easy to understand in his explanation,and it made every aspect easy to understand..excellent video; wish i would of watched this video before..makes all the other videos,a waste of time..this guy is a great teacher of basic wood working skills
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
It's possible that the cut depth was too great but what initially came to mind is the knives could have been dull. The work pieces really shouldn't be jumping around.
This is an excellent video! I had the exact question that you answered which is : "what is it about the mechanics of a planer that prevents it from creating a flat surface" and you were able to answer it by describing the mechanics behind both the jointer and planer as well as demonstrating it by running warped wood through both the planer and jointer. Thank you very much!
The infeed and outfeed tables are only considered parallel. Two parallel surfaces are not coplanar (do not share the same plane) when they are offset in height, they only share an angular orientation.
I went through a similar thing with my mitre saw yesterday. Wasn’t cutting square or at 90*, I hadn’t noticed until I was using oak. A few minutes of adjusting made all the difference to the work and the enjoyment.😊👍🏻 Do you ever go back to hand planing your timber, there is even more enjoyment doing that then with a power tool. I’m new to your channel so if you have posted a video like that I haven’t seen it yet.
Really great explanation and demo. You would make an amazing teacher, you seem so calm, your words are well thought out, and you obviously have great knowledge on the subject!
Great video and well explained. I think increasingly though hobbyists are choosing to use MFC, Plywood or MDF to build furniture. None of those materials require a jointer or planer. Many of the Ikea hacks posted on the Internet were done with nothing more than a drill and a circular saw. Working with solid hardwoods is great. But in many countries it is very expensive to buy.
Matt...As a newbie to woodworking I want to thank you for clarifying the difference between a jointer and a planer! I really liked how you explained everything.
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.
No Matthew Cremona Thank you! You are one of the most down to earth guys on youtube and watching your vids and laughs, im just glad you are sharing so much! cheers and keep it up!
When people put a bead of glue on a board, I always see them spread it. Is it necessary? What if you just run a line of glue, as you did at 11:00 and clamp the boards together without spreading the glue, would that cause any problems? Wouldn't the glue spread on its own from pressure between the boards?
This is not a jointer. It is a planer. It planes wood. It does not matter which way up the wood is, the process is the same- the wood is being planed. What would you call it at 90deg? 89deg? 91deg? A jointer makes joints. The clue is in the name. What you call a planer is a thicknesser. It is cutting wood to a specified thickness. How hard is this?
I was recently cut on my table saw. Now I'm pretty terrified of tools. I am wondering if it's safe to use a jointer. I have the opportunity to buy a nice one, but it looks incredibly dangerous? Are they dangerous?
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.
I wish I had never learned this. Now I want a jointer. I don't even have a shop yet

I do believe that the vast majority of people who watch youtube videos are doing so for "information or entertainment" and the vast majority of people putting out woodworking videos are so advanced in their skills that the information given is taken in more for entertainment than actual usable information.

👍Good stuff Matt. These machines have made it so much easier for a craftsman but not without its horror. I hope you don’t mind the following story. If it’s removed, I understand and all apologies. ✌️
*WARNING, GRAPHIC-
/My uncle was a 16 yr old junior in High Sch wood shop class, running boards thru the jointer when his hand slipped & went into the operating knives. I’m sure You can imagine the outcome of his hand. The one day LACK of safety changed his whole life. During his recovery he quit school & has never been the same. Almost a recluse his entire life. Never married, no kids, never a love interest as far as I knew. This was in the early 70’s. Sadly, Not a lot of mental health help back then. He’s now 60, has always been VERY self-conscious of the lack of fingers & many scars. I’m sure it’d be horribly tough to deal with such a life altering blow! Its my opinion, his most troubling scar is within his own heart & mind. Such a shame as he never let it go. My family has always given him our support but he never wanted any of it & chose his own paths. He’s always held a job but always a job in the shadows if you will.
I’ve often thought of this horror story while working w/ these machines & i believe it somehow kept me safe.
I’m not mentioning this happening for any reason other than to stress PROPER SAFETY.
Hope everyone’s projects go well and sorry if I over stepped here 👍
Thx Matt for the lesson. ✌️
Great video. Cleared up a lot of questions.
I liked your video and subscribed to your channel, great quality. I'm just starting and learning.
6:45] You've also turned the board upside down, the cup should always face *up,* or down? resting on two edges, hump up?- you should mention that soon.
This was perfect to understand!
Matt, what if 2 boards that you ran through the jointer and the planer come out to different thicknesses. It would seem like something that would occur if the boards had different levels of warp and twist. And if that happens, when you join them together, the boards wouldn't be flush would they? How does one account for this?
if you want a desired thickness you will need about 1/4 extra thickness stock to achive final thickness..if you want 3/4 you need 4/4 board, if you want 1" you need 5/4 board, if you want 1 1/4 you need 6/4 board and so and and so forth..
I wonder if I had a 12" jointer if I could use it to flatten a 24" wide board by removing the guard and running it through again with the other side against the fence.
Thanks
Matt, I think the term you were looking for was actually parallel planes, not coplanar. Coplanar would require the infeed and outfeed to be at the exact same level.
Jared Shaffer That's correct. I misspoke about that. I was thinking about them when they were level when they were being aligned. Thanks! :)
3:49 precise parallel planes would also probably work.
couldnt you joint both sides and avoid even using a planer?
Exactly what I needed to know, thanks!
+Pier Wouda Excellent! Thank you!
I'm sorry if I missed something you said, but it sounds like a jointer is a fix all tool. So if you have a jointer, why have a planer?
Haha never mind. I asked the question too early. I was a few minutes from the end when I posted the question.
haha just as I sit down to answer questions :)
Love this channel, subbed!
That's a nice looking piece of walnut
Tell me please, is the red device just a blade safety guard?
+niklar55 yes it's a safety guard. Thanks!
Matthew Cremona
Thanks.
helps a lot thanks!!!!
Awesome to hear! Thanks!
well here i was matt ready for a video, very good topic and you covered it very well, i really do like how you change your shirt for different parts of the video, keeps me on my feet matt...and on another topic...the pancakes over the weekend were fantastic, i found some good syrup ..:)>
Robert Putman Glad to hear I was able to keep you on your feet, Bob! Just finished mine. Late breakfast today, been working on getting this video out. Delicious as always :)
My planer is a jointer too.. and for the longest time i thought it's true for all planers
I'm here because 24 hours ago I had a 30 second conversation about a jointer with my phone in my shirt pocket. Surprise surprise, it appeared in my suggested videos.
I know what you mean. We're being watched by big brother "do no harm" Google
.40 S&W Fan a good service perhaps?
Similar situation here: I was talking about smoking a joint to relieve the pain in my joints so I could go dancing at a local juke joint.
@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?
@@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.
This is probably the most thorough tutorial I've seen on using a jointer... not only did you discuss what it does but you also discussed the biggest question in most people's mind about the relationship of planers to jointers. And to top it all you included proper technique. A+
Thanks!
Great lesson! I'm blown away at the effort given to properly explain the purpose and use of these tools. Thank You
Thank you for this great explanation. Jointer always seemed pointless to me if planers exist. You really set me straight!
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.
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
time for me to invent an automatic jointer
Matt.
I really enjoyed your video on the Jointer. It was very well presented and easy to follow. Your explanations were well thought out, and very informative. I am in the process of building my dream shop on paper and a Jointer will most certainly be on my list of wood working machines to have in my shop. Looking forward to watching more of your videos and increasing my knowledge about wood working. Respectfully Maurice Pettiford Budapest Hungary.
Thank you so much, Maurice! Have fun putting together your shop :)
I was looking at the Hammer by Felder and if I had it to start all over I'd consider a machine like that the only think it wont do is butter my toast. 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.
You can use for other stuff.
@@bobbg9041 which of the Hammer machines were you looking at?
My gawd you're a fantastic teacher.
FYI: On any jointer larger than 6", I think you're required to write "U.S.S. " on the side.
Kitty hawk
I dont get it? I must be missing something
@@thomasbarlow4223 if it weighs as much as an aircraft carrier - might as well label it like one
WeedMIC I believe it is because the surface of the jointer somewhat reassembles the deck of an aircraft carrier

"Hey wife . . . I was just watching this youtube video and it looks like I'm gonna need to buy another tool. It'll probably cost about a month's worth of income, but it will make nice smooth boards. Just saying."
"Hey hubbie . . . yer gonna have to deal with crooked projects. Just saying."
exactly what i'm dealing with.
Nah find a used one on craigslist. Jointers are the treadmill of tools. People buy them, and then the wife says she wants to [gasp] "park a car in the garage".
nicholas wolford that's a great description, perfect
This is very true. I see 800 dollar machines on there all the time less than 100 dollars.
Just don't tell her. She won't even notice there is a new huge machine in the shop cause *they all look alike* to them anyway.
Before today, and getting here from the Jamie Perkins accident, I didn't even know a jointer existed. But I enjoyed this video so much I subscribed. This guy is so natural I just gotta see what else he's got.
Same, googled "wood Jointer" after watching Jaime's video today and it brought me here.
Same. Small world
Nice demo with a great explanation Matt!
GuysWoodshop Thanks Guy!

Great video. I recently bought a jointer and had a hard time getting the boards flat. But now I know it's because I was applying too much pressure. Thank you!
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.
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.
Of the hundreds of videos I have watched on woodworking, this has been the most helpful. Thank you!!! :)
awesome to hear! Thanks!
The same “level” perhaps?
Because you’re a craftsman you like precision
nope, just Parallel Planes.
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.
@@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).
II'm new to wood working, and I ran bowed wood through the planer and to my surprise, it didn't come out flat. I'm getting a jointer now.
+BAdBrAd I bought it new from Grizzly
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
Yes
@@mcremona Nice Machine.
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.
Michael Perkins Thank you so much for the topic suggestion. This was much easier than trying to explain it by email too:)
Matthew Cremona Definitely! Keep it up man!
the surfaces on jointer are not actually coplanar, they're simply parallel.
+Piotr R ...jointer
ur rite!!
I think he was trying to use "trivially collinear" since two points determine a line.
@@browntrout3994 they aren't 2 points in a line. They are parallel to each other, but not in line. 1 is offset to account for the cut.
To be parallel you must be coplanar
Why don’t boards just come planed and jointed? I can’t imagine a project where you’d WANT a board that’s bowed or twisted. I understand wood bends and warps in transit, but as tools like these aren’t reasonable to have in a standard home workshop you’d think at least they’d offer it as a service at Home Depot or Lowe’s.
Mostly happens during the curing process. The moisture content varies drastically at places like homedepot. Next time your getting lumber take a second and you will notice the weight difference in a bundle of boards
Co planarity... Lol. Parallel my friend. Parallel
Jaze the tables are parallel and separated by the cut depth
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.
@@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.
@@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 ! ?
@738polarbear Not so great explanation when he's talking nonsense and also showing with his hands @ 4:15 about the cut depth being determined by the infeed table set lower (on a different plane) that the outfeed table, which is impossible for coplanar tables ! @Joe Ciccone is right in his comment @ 4:18 he also totally shows parallel planes not coplanar .
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.
Good additional comment. I actually noticed and noted the difference in the sound during Matt's demo.
I'm learning heaps today.
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.
@@l.clevelandmajor9931 Right... AND the proper clothing when working with this machinery, rather tide than loose, no long hairs hanging down.
@@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.
Another thing is if you don't use a jointer on a warped board,then send it through a non shop planer you'll get significantly more board snipe on the ends,from Hercules to Dewalt the small ones don't have the ability to hold the majority of the board flat so it will lift on and off of the ends as they pass through
Love your candidness and to the point style. Quite refreshing in a UA-cam world filled with polish and fluff.
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!
If Home Depot would buy a planer and a jointer, we wouldn’t need to have this debate.
As I’m working on my table I’m swearing and wishing I had one of these! The jointer would make everything go so smoothly.
You answered my question about using a hand plane first and then running it through the planner so heres my question-does it have to be a #4 or could i use a#5 jack plane?which wood be more sufficien? I just picked up a Stanley # 5 Jack from rockler other day. I have yet to use it .needs to be sharpened. But as always great informative vid. Looking forward to the next vid..have agood one matt!
Joe Walters You can use any plane you want. You're just looking to knock down the high spots so as long as you can do that you'll be set. Thanks Joe!
This isn't news for me but i wish i had this to watch when it was! You did an excellent job, the two glue ups especially tells the tale! I actually ran that experiment many times when i was starting out!!!! lol
lol Thanks!
Very good, clear explanation. The micro camera placed inside the machines was a great idea. Despite seeing several other vids that attempted to explain jointers, now for the first time, I understand how they work.
Thanks for sharing. I did learn something new. Who said you can't teach a old dog new tricks?
Saw Dust Maker I have never said that :)
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.
You can watch this video or you could've simply time traVEL to public school in Michigan in 1976. Where students aged 12-18 went to Wood Shop Class to learn such remedial things..
Wisconsin, 1991, had a wood shop, a nice one, a machine shop, a basic one that prepared you to enter the 1940's shop running in the 1960's, and an auto shop that was ok if you were interested in learning. Not sure if ANY of that still exists. Up until two years ago there were machining jobs open all over southern WI for ten straight years.
Simple explanations, very informative ...Great job Matt .
You know your stuff! New sub unlocked 👌🏽😎
The guy who gave you the thumbs down thinks you jointer is too small. Lol great vid
***** The only logical explanation! Thanks Dema!
Matthew Cremona What I want to know is why you used the small jointer and not the big 48" wide jointer you have. ;) lol just kidding...
Matthew Cremona Hi Matt, very good video! I have a solution to Dema's comment. You send me the jointer you showed in the video and that will free up space in your shop for a much bigger one. :) lol
Mike 61 your probably gonna get the same response as i do every time i stop by lol
***** Haha :)
Thank you, I have asked this very question and you have answered it perfectly
Awesome to hear! Thanks!
4:12 planes are parallel, but not coplanar. There are not two planes, if they are coplanar.
The Ask Matt videos are turning into a good "woodworking 101" series. Great work.
Kelly Burns Thanks Kelly!!
Hey. Great vid. I was trying to find out what a jointer is FOR, and you did an excellent job of explaining it.
Thanks.
Coplanarity coercion of compatible woods for cohesive copulation to a single board.
MRrwmac oh wow. Nice one Mac!
The tables are parallel, not co-planer. The feed table is slightly lower than the exit table; otherwise, nothing would be shaved off the board.
which is the definition of "coplaner"... tables are parallel on two different planes...
You'd think it would be the other way around. That a planer would make a perfectly flat plane, and a jointer would make a parallel surface that could be easily joined.
well... the planer is also called a "thicknesser" or "thickness planer" in some countries. That makes sense
Newbie here. So zero knowledge. Why is it called a jointer if it isn't making a joint?
It's preparing the wood to be put together as joints
They're not in the same plane. They're parallel.
+ophello Yes, one table is lower than the other to remove material. The top of the blade is in Coplane with the outfeed table.
ophello who cares bruh
Yea. He was struggling to find the words but he still explained what was happening correctly.
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.
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.
I always love your videos, i like how much detail you go into. I do have a question if you dont mind. I just got my first jointer and im having trouble flattening stock on it. I just some set up and put some cuts through on a piece of already fairly flat pine and the test piece came out perfectly flat after only minor tweaking. I then tried to flatten some pretty warped walnut (rough sawn, twisted, bowed and cupped) about as rough as it gets. And i just cant get them flat. they're tapered width-wise and still rock back and forth. Some of them are worse even-having a convex hump length-wise. What am I doing wrong? and how can I recover these boards?
When did Demetri Martin get his own woodworking show?
xD
Thank you Dmitri Martin!
Thanks for explaining this so a newbie like me can understand it.
this was a super informative video,on why to use a jointer,and planer..in the proper sequance,etc..very easy to understand in his explanation,and it made every aspect easy to understand..excellent video; wish i would of watched this video before..makes all the other videos,a waste of time..this guy is a great teacher of basic wood working skills
+jon b. Thank you Jon!
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
It's possible that the cut depth was too great but what initially came to mind is the knives could have been dull. The work pieces really shouldn't be jumping around.
thanks matt...you seem to have the right answer,and good suggestions...i appreciate your help....thanks, jb
This is an excellent video! I had the exact question that you answered which is : "what is it about the mechanics of a planer that prevents it from creating a flat surface" and you were able to answer it by describing the mechanics behind both the jointer and planer as well as demonstrating it by running warped wood through both the planer and jointer. Thank you very much!
The infeed and outfeed tables are only considered parallel. Two parallel surfaces are not coplanar (do not share the same plane) when they are offset in height, they only share an angular orientation.
I went through a similar thing with my mitre saw yesterday. Wasn’t cutting square or at 90*, I hadn’t noticed until I was using oak. A few minutes of adjusting made all the difference to the work and the enjoyment.😊👍🏻
Do you ever go back to hand planing your timber, there is even more enjoyment doing that then with a power tool. I’m new to your channel so if you have posted a video like that I haven’t seen it yet.
Thanks Matt, very helpful to me!
Awesome! Thanks Chris!
Really great explanation and demo. You would make an amazing teacher, you seem so calm, your words are well thought out, and you obviously have great knowledge on the subject!
Exactly what I needed to know. Thank you
Great video and well explained. I think increasingly though hobbyists are choosing to use MFC, Plywood or MDF to build furniture. None of those materials require a jointer or planer. Many of the Ikea hacks posted on the Internet were done with nothing more than a drill and a circular saw. Working with solid hardwoods is great. But in many countries it is very expensive to buy.
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...
I'm gonna take a jointer into my local Home Depot and fix all the "Wonderful" wood. I would be doing a public service.
Exept that when the wood is stored for a long time after using the jointer, it might warp/twist/cup again.
Matt...As a newbie to woodworking I want to thank you for clarifying the difference between a jointer and a planer! I really liked how you explained everything.
We mostly call them buzzers or surface planers here, been using them for almost 40 years.
I don't think they're the same plane, just on parallel planes, right?
Why? Man, I don't even do anything with wood, and i understand.
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.
Majid Al Qassimi You're absolutely right. I misspoke. They are parallel planes. They'd be coplanar if the cut depth was 0 :) Thank you!
No Matthew Cremona Thank you! You are one of the most down to earth guys on youtube and watching your vids and laughs, im just glad you are sharing so much!
cheers and keep it up!
Majid Al Qassimi Thank you!!!!
When people put a bead of glue on a board, I always see them spread it. Is it necessary? What if you just run a line of glue, as you did at 11:00 and clamp the boards together without spreading the glue, would that cause any problems? Wouldn't the glue spread on its own from pressure between the boards?
Great as always!
This is not a jointer. It is a planer. It planes wood. It does not matter which way up the wood is, the process is the same- the wood is being planed. What would you call it at 90deg? 89deg? 91deg? A jointer makes joints. The clue is in the name. What you call a planer is a thicknesser. It is cutting wood to a specified thickness. How hard is this?
A lot of great information on joiners Matt!
AdventuresInDIY Thanks Chris!
I was recently cut on my table saw. Now I'm pretty terrified of tools. I am wondering if it's safe to use a jointer. I have the opportunity to buy a nice one, but it looks incredibly dangerous? Are they dangerous?
Why demonstrate when ten thousand words will do.
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.
MAGA MAN I am very happy he explained it the way he did!!
LMAO 😂😂😂
Why do Americans call a planer a jointer, and a thicknesser a planer? A jointer makes joints! So confusing...
