What Does a Jointer Do? - Ask Matt #13

A jointer is a very important tool in a woodworking shop. Its job is to set the foundation for all future work you will be doing with a board. Being able to properly mill a board flat and true is a fundamental task in woodworking because flat work pieces lead to more precise and consistent joinery in your projects.

@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.

[@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.

[@smashedagain420]

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

[@johndrennanjr594]

Simple explanations, very informative ...Great job Matt .

[@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.

[@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.

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.

[@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.

[@duncan4735]

Thank you very much. I have often seen people used joiners, but never understood their purpose. I love that you compared it to a planer, both explaining and showing the difference and how to use them in conjunction with each other.

[@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.

[@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!

[@trick58]

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.

Hey Matt, I haven't watched your stuff for a little while, not for any reason, just been busy. It was really awesome to watch this. Thanks for the great advice

[@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.

[@jbrisby]

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.

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!

[@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 ! ?

[@DemasShopforEverything]

The guy who gave you the thumbs down thinks you jointer is too small. Lol great vid

[@mcremona]

***** The only logical explanation! Thanks Dema!

[@KSFWG]

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...

[@Mike-uj1wr]

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

[@DemasShopforEverything]

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

[@Mike-uj1wr]

***** Haha :)

[@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!

[@evelyn_r]

I had an idea what a planer did but thank you for taking the time to explain it, as a lot of people skip it as they assume we newbies automatically know. Great vid 👍

[@kevinitwaru5919]

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

[@Visigoth_]

I Care!

[@mcremona]

Nathan Stoddard hahaha!! Thanks Nathan!

[@jcarey65]

This was the best explanation I have seen! Thank you so much!!

[@ForrestHuff-ni6dz]

I just scored a vintage jointer on OfferUp! This was extremely helpful. After watching some restoration videos, this was helpful to see what is the most important aspects to focus on.

[@vashon100]

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

[@ericmatthews3307]

When did Demetri Martin get his own woodworking show?

[@joshuamiller4108]

xD

[@alovemetropolis]

The information in this video is exactly what I needed to learn. Thank you.

[@7shameik]

Excellent delivery and information

[@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.

[@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...

[@mantaship]

This is the best, the clearest, and most straightforward answer to jointer vs planer with clear demonstrations I have seen. Thank you! Demystified...

[@mcremona]

Thanks Will!

[@mariewood8267]

That is so wild. It took a bit to wrap my mind around what you were saying. Thanks for the explanation!

[@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 😂😂😂

[@cheekychapman1]

Such a helpful overview of these two items - thank you

[@s85593]

Great video. Cleared up a lot of questions.

[@ovaldobraun4464]

this is an extremely helpful video. you have a real natural knack at making things easy to understand. I was wondering why my planer wasn't doing a jointers job. thanks for posting

[@mcremona]

Thank you! Glad it was helpful!

[@petertse6900]

You are a very good instructor and teacher
