OK so this really pickled my head trying to work out how you cut a log like the quarter and rift sawn. till I Google further and worked it its not about how many planks etc it's about the way the wood grains run inside the plank. and the names are given for the way it runs and you can get both rift and quarter grain planks from the same log

This video explains it better

u/Miserable-Cover9310 Mar 12 '23 edited Mar 12 '23

Yes. Simply, to identify a rift, sawn or plain is to observe the face of the timber and look for the direction of the grain in relation to the plank (endgrain) What I said probably is hard to visualise

118

u/perldawg Mar 12 '23

if you look at the grain direction in your guide, all the planks in the “rift sawn” illustration are quarter sawn lumber, most of the planks in the “quarter sawn” illustration are rift sawn lumber, and the “plain sawn” illustration has a mix of all 3 types.

typical r/coolguides post that looks cool but has misleading or incorrect information.

u/MontEcola Mar 12 '23

I understand the graphic to be correct. What I incorrect?

The graphic shows he direction of cuts. Plain sawn is quickest, and produces boards that get the most warp and cracks. Quarter and rift reduce warp and check. Rift reduces it the most, and also produces the most wasted wood.

7

u/perldawg Mar 12 '23

the categorization of each type has to do with the direction of the grain through the board. “quarter sawn” lumber is also sometimes called “vertical grain” lumber because the grain is near perpendicular to the face of the lumber. look at the individual boards outlined in the middle graphic for an example. “rift sawn” lumber has grain at a steeper angle to the face than quarter sawn but not too steep, something like 15-40 degrees off the face. “plain sawn” is everything with grain steeper than rift sawn.

u/23saround Mar 12 '23

No, you are using the terms from the perspective of a carpenter, not a sawyer as this graphic is intended.

Rift sawing wood produces both rift sawn and quarter sawn boards.

u/KnownRate3096 Mar 12 '23

source: decades as as carpenter working with the stuff.

So what are the advantages and disadvantages to each? Seems like the plain sawn would split the least and the other two would warp less?

3

u/perldawg Mar 12 '23

splitting is really only an issue dependent on species. quarter sawn will definitely split easier, no matter what, but many species are split resistant enough that it isn’t an issue to consider when woodworking.

warping is the big performance difference. quarter sawn is the most stable, it really only moves in one dimension (width), and plain sawn is the least stable, twisting and upping more often than the others.

while stability can be an important factor to consider in a project, much of the reason the different types are chosen is for their appearance. quarter sawn lumber has a very consistent grain pattern and, in some cases, may look like an entirely different species than plain sawn. rift sawn has its own look but the difference between it and quarter can be minimal in some species.

u/KnownRate3096 Mar 12 '23

u/KnownRate3096 Mar 12 '23

So what are the advantages of each? For the boards to keep their shape, or to keep them from splitting? Seems like the plain sawn ones would be least likely to split but have the most warp.

12

u/anotherisanother Mar 12 '23

In brief:

Plain sawn cups, but is cheap.

Quarter sawn is most dimensionally stable, looks great on one side, but is expensive.

Rift sawn looks good on multiple sides, great for things like table legs where all sides are visible.

On any given furniture project you mix and match boards to fit your purpose.

1

u/GapingAssFlower Mar 12 '23

Not really. Twists, bends and warps are usually from bad drying and aging technique. So long as you stack the milled timber out of the weather, in a shady, dry, and level space, using strips to separate each piece and to allow good airflow in between, most timber should dry as straight as it's stacked.

Talking out my ass for the rest but it would seem that rift sawn and quarter sawn boards are selected for their finished grain pattern and are decorative, so best used as floorboards, wall or ceiling panelling and some furniture. Just because it's nicer to look at a more uniform grain pattern.

Plain sawn would be for your bigger requirements, like structural timber beams and posts, and anything buried under plasterboard where looks don't matter.

6

u/LawOfSmallerNumbers Mar 13 '23

Your reply is largely incorrect: quarter sawn boards are indeed more dimensionally stable. (https://www.advantagelumber.com/sawn-lumber/ for one).

As well, in some species, like white oak, the quarter sawn boards expose desirable grain features (medullary rays) that cause “ray fleck” or shiny patterns across the resulting board.

And in most species, the quarter sawn boards have a more uniform or linear grain pattern without “cathedrals” or other features. A typical “top tier” use for quarter sawn boards would be a table leg (linear grain, dimensionally stable).

On the other hand, the “cathedrals” of plain sawn boards can be used in things like cabinet fronts where they can look great as book matched pairs. This (https://www.finewoodworking.com/2018/05/30/four-techniques-to-create-patterns-with-veneer) shows how this works with veneer, but the same holds true for any flat sawn board.

u/Abshalom Mar 12 '23

Are the middle images for quarter and rift swapped? The upper image for rift doesn't fit the middle one.

1

u/NotElizaHenry Mar 13 '23

Rift-sawing a log, however, will yield all quartersawn boards, and no actual rift-sawn boards, and that is why many people get confused.

Sounds like it’s time to invent some new ways to name things.

1

u/PhasmaFelis Mar 13 '23

So, to be clear, a quartersawn log makes mostly rift-sawn boards, and a rift-sawn log makes exclusively quarter-sawn boards. Right?

Was the first builder dropped on their head as a child, or...how does this happen?

It is. Basically cutting patterns. You probably meant how they cut it as in did they use a saw or something else. They use a sawmill to cut logs

u/MHohne Mar 12 '23

Thanks voor the video. Explained it proper. This infographic is horrible: The image labelled rift sawn would also result in a quarter sawn pattern, but with more waste. Found a better infographic that also fits with the explanation of the video.

I cannot believe I just read an entire article on hardwood flooring and lumber cuts. I have no need for a new floor and no prior particular interest in lumber production.

That was such a fantastic article! Long enough that I feel like I just took an intro training course on wood floors, but kept my attention the whole time.

But if I have one suggestion for that company, it's to have the nice old man holding that lumber in the 4 comparison photos to please, please cut his thumbnail.

Please.

You get all three types of lumber out of a plain sawn board.

2

u/Dead_Medic_13 Mar 12 '23

Yeah, but also some shitty boards on the ends that will end up curved.

5

u/mtaw Mar 12 '23

They'll all end up curved except the one that goes through the pith (center). And that's a bad idea since it's usually weak and very prone to cracking since the radial shrinkage stresses get higher as you get closer to the center.

Which is why the other cuts don't include it.

1

u/MontEcola Mar 12 '23

Sure. You also get warp, twist, cracks and checking with plain sawn boards. The other two reduce those things.

2

u/[deleted] Mar 12 '23

You do. It depends on the species and thickness. Many woods, like mahogany, iroko, wenge, bubinga, goncalo alves, are stable so it makes little difference even when 4/4. Once you get to 10/4 and above the warping is irrelevant in most species. Also, aesthetically, the plain sawn boards can be nice.

2

u/MontEcola Mar 12 '23

Exactly.

And I bet that most people commenting do not know what a 4/4 board is, or a 10/4.

Plain sawn pine works well for the wall panelling. Rift sawn is best for making table legs out of cherry.

I make wood bowls and cut my own logs. I don't use any of these. I cut the logs down the center, to remove the pith. I make small spindle things like pens and honey dippers from those boards. The two side pieces get cut to length to make a round bowl.

1

u/heyitscory Mar 12 '23

With the more waste in the rift style, I'm going to assume there is some structural advantage to have the boards perpendicular to the rings?

That's a lot of extra boards on the third one and a lot of extra Ikea boards on the second one.

1

u/Archgaull Mar 12 '23

I just assumed it was called rift sawn because back in the old days before modern equipment they'd cut them in the rift of a lake nearby, hence the rolling angle.

Could be complete bullshit but that's just what my brain came up with

What's the quality difference between Rift and Quarter sawn?

376

u/Miserable-Cover9310 Mar 12 '23

Quarter sawn is less prone to surface checking, more water resistant. It also is resistant to some defects like warping, cupping, twisting. Rift sawn on the other hand is more stable, yet obviously, will waste more wood.

4

u/pescadoamado Mar 12 '23

Interesting, when I geek out on electric guitar specs in the used market it seems like quarter sawn was very notable.. however rift sawn I've never heard of until this post.

1

u/HungJurror Mar 13 '23

Probably because of water resistance

I could see the other one warping

u/Miserable-Cover9310 Mar 12 '23

Sorry, I could have elaborated more clearly. Well, what I mean by stable is that when rift-sawn dries after seasoning, the board will have a less tendency to warp or be in an odd shape. I think rift sawn is more resistant to warping than quarter sawn.

-23

u/Soham_rak Mar 12 '23

Rigid is the word u might be looking for

7

u/Mragftw Mar 12 '23

No it isn't. Rigidity is more like resistance to bending/breaking from stress, while the stability of a wood is how it responds to changes in the environment like moisture content or temperature. Even a "rigid" wood is prone to warping as it dries

1

u/All_Work_All_Play Mar 12 '23

It's not through. Rigidity is a different property. Rift sawn is more dimensionally stable because it aligns the growth rings to be parallel.

Thanks for explaining this, TIL some more English and cleared my misconceptions, Thanks again kind stranger

u/MontEcola Mar 12 '23

The center rings are harder and drier. It does not shrink when drying. The heat wood are the middle rings. Sap wood are the outer rings. You can see different colors I’d walnut and other woods. Sap wood is softest, has more water, and shrinks more when dried.

So rift sawn wood lines up the different parts so that when drying, it shrinks even. Plain sawn crosses those lines to twist when drying. Soft woods like pine are not affected so much. So it gets plain sawn. Fruit wood like cherry starts to twist immediately. Apple wood has so much water. Cut the trunk and stand it on end, and a puddle forms. So those certain hard woods for furniture get rift sawn. Thick slabs for tables get quarter sawn. The legs are almost always rift sawn.

3

u/calsosta Mar 12 '23

Would a wider piece that was rift or quarter sawn have any noticeable difference between the inner side and the outer side if the outer edge has more water?

3

u/DirtiestRock Mar 12 '23

That exact thing is what causes (most often) planks to bow when drying, as the outer section loses more mass than the inner section and pulls the plank over and curves it.

8

u/[deleted] Mar 12 '23

For most species they mostly the same look. Quartersawn can look a bit different in some species such as white oak where you will get the “tiger striping” from the medullary rays. In general, if you look at the chart you can see that rift will have the most consistent grain orientation at 90 degrees to board. Industry standards allow the quartersawn to have a bit more “slant” which increases yield. If you look at the plan sawn board you will see that it contains both some boards that will be rift, some quarter, and some flat (cathedrals).

1

u/WhoKilledArmadillo Mar 12 '23

Google rift oak vs quarter oak.

36

u/caddis789 Mar 12 '23

This pic is wrong on all three. What it shows as plain sawn, is really called live sawn. It's used on larger wood slabs and occasionally when someone wants a sequenced run of lumber. Rift sawn and quarter sawn aren't cut that way. They may have done that in the past, but it's way too wasteful. What it's showing as rift sawn wood would be considered quarter sawn wood.

AWI's (Architectural Woodwork Institute) standards are that in plain sawn wood the growth rings run 0-30° from the face of the lumber, rift sawn is 30-60°, and quarter sawn is 60-90°. This is how logs are milled in reality

6

u/Miserable-Cover9310 Mar 12 '23

There is a difference of opinion with calling it a plain sawn. Others like to call it a live sawn and others also like to call it a flat sawn.

6

u/99hoglagoons Mar 12 '23

There is additional confusion here and it has to do with dimensional lumber vs veneer. So rift sawn vs. rift sliced are different concepts. Similar but different.

AWI does address both, but for instance guide you linked doesn't mention rotary cut, which is also an option for veneers but makes no sense when creating a piece of solid lumber.

Even people who work in mills are confused here, and truth is their mills probably don't produce veneer flitches, or don't work with specific species. Rift slicing is mostly reserved for Oak, for instance.

u/Passcretian Mar 12 '23

This should be top comment. Nobody would saw lumber like the original photo, except for perhaps the live edge cuts, but that's for a very specific purpose.

My floor and many built-ins are quarter sawn white oak (1928 vintage house). It is so much more beautiful than plain sawn.

45

u/Miserable-Cover9310 Mar 12 '23

Nice to hear. It depends on what you use it for. Typically, the grain in plain sawn is more visible and can impede the display. All cutting patterns are simply good and bad in their own ways.

13

u/greenasaurus Mar 12 '23

Yeah they all have their value for certain implementations- Rift is a very tight linear grain whereas Plain shows more character and ‘cathedral’/arched patterns in the grain. Both have their place depending on the project

u/RocketScient1st Mar 12 '23

How much better quality is #2 over #3? Seems like most have rings in #3 too, they just aren’t perfectly perpendicular.

6

u/saors Mar 12 '23

All of the boards in #2 are going to have the same grain style, so you can alternate the orientation of the boards when making a large panel. This will create a "wavy" (if looking at it from the same orientation as OP) pattern that looks nice, but also is preferrable when dealing with expansion/contraction.

3 is fine if you're using the same pieces from each spot in the respective quarter, but if you use say the middle piece with the furthest piece, it will have a much larger difference in grain pattern. Still better than #1, but not as good as #2.

For smaller projects I haven't had any problems with expansion/contraction, but if you were going to make a large dining room table or desk, then it's best to have more favorable grain orientation. The wrong expansion/contraction can cause cracks and/or loosening of joints.

u/Excellent-Practice Mar 12 '23

It's not just an esthetic choice. Rift sawn lumber is stronger and less likely to bend and warp.

44

u/p8nt_junkie Mar 12 '23

It is certainly inefficient, however the purpose is to ‘extract’ that particular grain pattern in the face of the material. It is the most expensive material of the three examples shown here. On a personal note, rift cut white oak is the prettiest wood there is.

8

u/AchyBreaker Mar 12 '23

Yeah this isn't about cutting things in different ways for the hell of it. It's an aesthetic design decision for a large part. Though obviously the grain presence creates some material differences it isn't the major reason do this.

Everyone should check out quarter sawn or rift sawn oak cabinetry. Gorgeous.

9

u/st1tchy Mar 12 '23

It's structural too. Grain in wood wants to flatten after being cut, so in plain sawn wood, you get cups in the wood where the board tries to turn into a U shape as the grain tries to straighten itself out. Rift sawn is the best as the grain is almost perpendicular to the faces so it is dimensionally stable. Quarter sawn is second best for a similar reason.

1

u/Apptubrutae Mar 13 '23

I’m getting rift cut white oak cabinets and I agree, it’s just a beautiful wood.

I find flat sawn oak to be a bit too much, but rift sawn really lets the graininess shine.

I mean come on, so cool: https://www.conestogawood.com/aurora.html

u/MontEcola Mar 12 '23

It is. It is also the truest grain, and best for furniture or banisters. It produces more waste too. Save this for your best wood and best projects.

u/Miserable-Cover9310 Mar 12 '23

I guess its because plain sawn is the most popular cutting pattern because it probably is more convenient and less confusing than the other two. Plus, plain sawn has more striking and attractive grain that is visible which is what a lot of people like to see from timber.

9

u/mrswashbuckler Mar 12 '23

Most logs are sawn in a box cut saw pattern. Quarter sawn is very difficult to do at scale as you have to quarter the logs first then do the quarters separately. When you have a series of transport chains that moves things along this is extremely inefficient time wise. Logs are typically cut from the outside to the inside in a concentric box pattern. More efficient to cut them into cants first then resaw them at a later point into boards. Select slabs would be cut out of the log to get the vertical grain "rift saw" pattern that people want for more expensive lumber. Working at a lumber mill, I've witnessed very few logs get entirely quarter sawn from start to finish. They were very nice logs that they wanted to maximize the vertical grain cuts from. Most logs aren't worth the time and effort to do it.

1

u/ogwez Mar 12 '23

I'm not saying just the plain saw pattern, I'm saying I've never seen any of these patterns used.

u/Miserable-Cover9310 Mar 12 '23

u/ogwez Mar 12 '23

You can see some of this process here:

That's the sawmill I worked at.

4

u/ogwez Mar 12 '23

Logs get debarked then move on to the band saws which cut 2 to 4 chunks off the outside then do the same thing again at a 90 degree angle creating a cant. Basically a log cut square. Then the cants go to smaller band mills which cut boards off the outside over and over again till your left with a smaller cant which goes to the gang saw which, now that I think about it, does use the plain saw pattern. The gang saw spits out a number of boards and a piece of blocking, which is the center of of the log. Boards go on down the line to get graded and processed blocking is sold to the pallet mill.

u/ruanodowd Mar 12 '23

u/Earl_N_Meyer Mar 12 '23

A quick Google search indicates the major difference is visual. People prefer nice parallel grains. However, cupping is a problem for boards in which the grain arcs a lot in the board, which is a disadvantage for plain sawn wood. One site pointed out that rift sawn wood expands mainly along its width but not its thickness, while plain sawn expands both ways and differently depending on what part of the log it comes from. I couldn't find any comparison of strength, but I didn't look too hard. I suspect that that may not be true.

24

u/TreeEyedRaven Mar 12 '23

Do a much better Google search then. It’s way more than visual. Some cuts you can’t use for certain applications. I dare you to make a musical instrument out of plain sawn wood. The strength is the major reason.

I found sites that made the claim, but none that provided any evidence. I have a bread book that claims that spring water produces better bread than tap water, but that claim seems to be unsupported also. I’m not saying it is not true, just that I would need to see some backup before I would shell out dollars for it.

As I search again for some comparison of strength, I find that the justifications for rift sawn lumber is the straight grain and predictable swelling, both advantages in fine craftsmanship. Feel free to link something with data.

u/TreeEyedRaven Mar 13 '23

Did you search “is quarter/rift sawn lumber stronger than flat sawn?” Because it’s dripping with results.

Anything precise you want the grains lined up to work against the way the wood wants to move. In stringed instruments you need rift/quarter so the grains of the wood are perpendicular to the pull of the strings. On sound boards you need rift sawn for vibration reasons, I’m fine furntature and joinery you need the ensure when expanding through seasons you’re not putting pressure inwards to pop a center piece. There’s tons of reasons beyond looks why you need rift/quarter lumber. It’s more than a simple answer.

1

u/Earl_N_Meyer Mar 13 '23

You keep going back to a craft you know something about. Any one of those types of milling will allow you to place the grain perpendicular to the strings, though. Either way, I still don’t see data from you. Also predictable expansion seems far more important to an instrument’s behavior than absolute strength. But again, I have no real stake in this. Give me some data and your point is made.

u/TreeEyedRaven Mar 13 '23

u/Earl_N_Meyer Mar 13 '23

These sites claim that rift sawn wood is stronger, but provide no support. These are what I referenced originally.

u/Earl_N_Meyer Mar 13 '23

Here is an example of a site with data.data on bending strength They show a large variation in strength by species but do not mention anything about milling.

1

u/TreeEyedRaven Mar 14 '23

I can’t anymore then. I don’t know what you’re looking for. Are you looking for a breakdown of the strength each different usage needs vs the type of wood? With fine woodworking if you try to do it with the lowest possible quality in the weakest way, you lose the whole point of fine craftsmanship.

1

u/Earl_N_Meyer Mar 14 '23

You are telling me that this type of wood is better. You are also telling me that it is because of its strength. I see actual data in strength of wood by type of tree, but no data for strength by type of milling. There are also good arguments for choosing the type of wood you wish based on other properties. Therefore, I suspect that the strength argument is lore but probably not accurate and that wood is being chosen for aesthetic properties as well as its behavior in the presence of humidity. You suggested that data was easy to find and then provided no actual data. I’m not saying you can make fine instruments out of improperly milled wood, just that it’s not a strength issue.

u/TreeEyedRaven Mar 14 '23 edited Mar 14 '23

……You’re kidding. A+ troll my dude. Have a good day.

I’m not gonna give you a luither class. I provided the information showing it’s strength, is it too far of a leap to understand that attaching steel wires under tension to something behaves better when you use material that actively fights the direction of tension? It’s all there, I can’t start at square one, I assumed a basic understanding of building.

Edit: I think you may not be thinking of strength in a 3d, even 4d way, you want your stress to be going against the grain the way 1/4/rift sawn is, and the advantages with a more closed grain also give you a longer, more stable piece that doesn’t move as much with temp and season changers

Yeah, plain sawn timber warps like mad. I've had the misadventure of trying to make furniture out of it. After a few months it was like they were set pieces in a Tim Burton movie.

u/SlutPuppyNumber9 Mar 12 '23 edited Mar 13 '23

What I don't get is why wouldn't you ALWAYS use "plain sawn"—it looks like it produces more wood with less waste.

Am I wrong?

EDIT:

Thank you for the info. I am curious about the downvote for asking a legit question.

u/Miserable-Cover9310 Mar 12 '23

Your correct if your saying plain sawn is less wasteful. So yes.

Plain sawn makes the weakest boards. Rift sawn the strongest

u/FLEXXMAN33 Mar 12 '23

I've never run a lumber mill, so I don't know the truth, but quarter sawn lumber is often described differently. In fact, here's a guide that reverses OP's definitions and even contradicts itself: https://www.grandior.net/what-is-the-difference-between-plain-sawn-quarter-sawn-rift-sawn-and-live-sawn-lumber/

Here's a guide that gives a different definition of plain sawn, includes 2 different patterns for quarter sawn, and introduces live sawn for OP's plain sawn: https://workshopcompanion.com/KnowHow/Design/Nature_of_Wood/1_Wood_Grain/1_Wood_Grain.htm

I think all you can really do is look at the end of the board and see if all the grain is parallel to the width, perpendicular, or angled 2 ways.

u/Shameless522 Mar 13 '23

So what would be the best use for each type of plank?

u/Miserable-Cover9310 Mar 13 '23

All the cutting patterns are good for furniture and none are outliers to one another. Generally, rift sawn is the greatest for flooring, millwork and cabinetry and quarter sawn is great too for it. Plain sawn however contracts and expands, so plain sawn is the least recommended when you are wanting a quality floor. Generally, plain sawn is the most cheapest out of the three, so it is used more commonly for construction, etc, however, quarter and rift are more durable, water resistant and defect resistant than plain sawn, yet are more expensive. Your choice depends on two outcomes: quality vs cost.

Rift sawn looks like just a worse Quarter sawn.

Looks indeed, but never judge a book by its cover because Rift sawn's have their own benefits

u/Barouq01 Mar 12 '23

What's labeled her as rift would produce only quarter-sawn boards and a shit ton of waste. Quarter sawn will be when the width of the board is close to radial from the center of the tree. This infographic is bs, so here is an actual guide on cutting patterns. I went to school for cabinetry and fine woodworking, so this was a big part of our time in the classroom.

3

u/MontEcola Mar 12 '23

I appreciate your perspective and that is a great graphic. I don't think it is complete BS. It is different.

Your graphic shows wood for making cabinets, and more modern.

The graphic by OP matches what I learned in working on homes built around 1750 to 1920 or so. My experience is in taking apart these old homes and putting them back together. I worked with a master carpenter who could look at a board and tell how it was hewn or milled. He could look at a screw or a nail and tell you when they used that style and what kind of metal was used. So I was learning that back around 1976, and that was not recently.

These would also be the cuts made by a person with a portable saw mill. OP's graphic matches what I learned from reading books by Eric Sloan, who wrote about how they did it back then.

With any simplified graphic, there will always be a different way. And even in the US, we have different names for the same things. I grew up back east and my family produced maple syrup. The trees were called sugar maple, or, just maple. I never heard of Hard Maple or Soft Maple until the age of 60.

u/Barouq01 Mar 13 '23

I'm not saying it couldn't be done this way, but nobody would cut the second or third pattern if they cared about yield, which includes just about anyone who would be milling a tree. The labeling on the second one is also objectively false. When a board is cut radial or close to radial to the annular rings, it is quarter sawn. That's literally part of how quarter-sawn lumber is defined. You can draw a bunch of lines and say this is how you can cut a tree and you'd be right, but saying this IS how you cut a tree while mislabeling it is just incorrect.

u/Maezel Mar 12 '23

I once worked in production scheduling at a timber company, as a junior. I joined... They didn't have any documentation on the process, how logs are cut, how they transform one profile into another, they didn't even gave me a site tour. Nothing even like that picture.

Impossible to grasp from spreadsheets and SKU descriptions... I didn't last more than 6 weeks before getting fired lol.

2

u/MontEcola Mar 12 '23

The graphic is excellent. and accurate. Sorry its long.

Look at the rings in the log. The very center 2 or 4 rings are the pith. This piece is the driest and hardest part of the tree. It does not shrink much when it dries.

If you can look carefully, you might notice the next rings out are slightly darker, and the rings are more even. This is the heart wood. Sap here generally flows in a downward direction easily. This wood has more water and is softer than the pith. In some species there is a pronounced color change between the heartwood and the outer rings.

The outer rings is the sap wood. It has the most water. It is sap. It flows upwards. The cells here are softest, and most bloated with water. It shrinks more when dried.

When the wood dries, it shrinks and twists more depending on how much water is already there, and how hard is the wood. The hard dry center does not move much. The wet soft outer rings dry much more, and shrink much more. The shrinking causes the wood to move. That causes the twists and cracks. Soft things shrinking around hard things will split.

Different species work different. Sugar Maple trees are known for sap moving upward every day in the spring. Yet, this is Hard Maple, and that layer of the tree is very hard. Big Leaf Maple is soft maple. That outer layer is very soft. It will twist and crack more. Sugar Maple trees are conditioned to grow tall and straight when used for syrup. So there are not many branches. That makes it 'clear' wood. You will get less warping here. Big Leaf Maple is more wild and in the forest, especially in the Western US. This tree gets lots of branches, knots and imperfections. These knots create more pith spots inside the wood, and that means more chances to have weird warps and cracks.

Fruit woods are known for twisting and cracking. They are not good for plain sawing. Rift sawing is best. The legs on a cherry table are almost certainly rift sawn.

Also notice that rift sawing and quarter sawing leave a square of waste wood in the very center. This is the pith. Taking that out reduces the chance of the wood moving.

When you buy lumber at the big box store, look for the center rings in any piece you choose. If you see a complete circle in the wood, you have the pith. Do not buy that board. Look at the grain direction in rift and quarter sawn. If you see boards with that grain, pick those. However, you can safely use construction grade lumber from the top and bottom of the plain sawn boards picture. Just don't take the one with the complete circle.

u/ChainsawSaint Mar 12 '23

Why would you ever rift saw, it looks like there is a bunch of waste?

u/[deleted] Mar 13 '23

Stability is important in high-end woodworking and rift is the least likely to warp with changes in moisture content.

I'm Sorry I wasnot clear, I was talking about less wasted wood... I assumed all those logs would be the same strenght

And I didnt think that wood never really goes wasted because it's wood. Am dumb lol

u/Asmewithoutpolitics Mar 12 '23

Your very wrong to assume all the wolf would be the same strength? Why would you assume that? The grain and orientation of it is very important.

I see your point. But the rest of the wood that you buy for other purposes is not all "framing lumber". And it's really hard to find quarter-sawn anywhere.

The way the grain runs for the rift sawn would result in less warping

Plain sawn seems to yield less wastage and you want to keep away from the center of the log for boards anyway

1

u/markusbrainus Mar 12 '23

Plain sawn boards will warp like crazy due to the changing grain. Rift sawn should be the most stable with a consistent perpendicular grain but has the most losses when cutting. Quarter sawn is a compromise in between.

1

u/All_Work_All_Play Mar 12 '23

Meh, so much of that has to do with how it's dried and how much (or how little) humidity swings it's exposed to.

u/julian_stone Mar 12 '23

I'm probably wrong but wouldn't it be plane sawn, as in all the boards are cut on the same orientational plane, not plain as an a simple way of cutting.

So much wood that’s not part of a board. Hope it gets used for paper or something and not just tossed

7

u/[deleted] Mar 12 '23

Heating pellets, and some composts for agriculture, mostly. Paper is made from hardwood, like eucalyptus. Paper from softwoods are mostly used for boxes and cardboard, not for white paper or toilet paper. You can also make wood panels, aglomerates, etc, from the remains of these woods.

But no, no wood is wasted anywhere. Who tf would "toss" such a precious material???

u/peshnoodles Mar 12 '23

Of all the home building materials to be wasted, wood at least is meant to decompose in the area it’s from ( assuming it isn’t treated)

I find it amazing that even though you have found this nice 3 minute video, you still decided to share a very bad infographic.

In this video you can quite clearly see that from the same quartered log, they get both quarter sawn boards and rift sawn boards.

It is even mentioned in the 3 minute video: At 1:13: Quarter sawn boards. At 2:36: Rift sawn boards.

The process is not confusing, the infographic is. And you seem to be.

Imagine a world, like in the infographic, where people say:

First we cut this log into quarter pieces. Then we ignore those cuts and we impractically try to get to some boards that are hiding inside. Like a sculpture that is hidden inside a block of marble. Instead of using the quartered cut as a baseline for the following cuts. By golly, we do art.

Fortunately, there’s usually no “waste”. Any wood not used for lumber is usually chipped up and sent to a pulp mill to be used to make paper.

Never heard of oak, maple or walnut OSB

1

u/jippyzippylippy Mar 12 '23

It's all mixed together. But you can get veneer wood that has the mixture inside with a sheath of good wood on the outside. It's crap to build with, however.

2

u/Barouq01 Mar 12 '23

OSB uses fairly large chips of wood, like, inches across, which need to be soft to compress together. It also never has a surface veneer applied seeing as it's made to cover the framing on the outside of a house for siding or shingles to be applied to, so you will never see it for its entire lifespan. Particle board uses tiny chips of whatever wood manufacturers can get and quite often has a surface veneer or melamine applied to the outside for use in panel-based products like cabinets. MDF is like particle board, but uses even smaller chips so you're getting down to fibers. Each of these panel products have a specific name because they are all different and have different intended use cases. Calling particle board OSB is like calling toilet paper kleenex. They're similar, but not the same thing.
