Decent wood glue was only invented during the industrial revolution. The best glue available historically was literally gelatin, subject to decay and water damage, and almost uselessly weak by modern standards (it holds on in niche uses where a glued joint needs to be able to be taken apart later without damage to the wood). So woodworkers developed fancy joinery to get strong, stable joints with little or no need for glue.

Nowadays, it's mostly for the sake of matching traditional styles. The availability of cheap and strong adhesives and mechanical fasteners means that an engineer won't specify a fancy joint unless the client wants that particular style.

Yes they did, and no it isn't. It can be used as a sticky binder / sealer for fibrous things that actually carry the load, but it doesn't do much as a structural adhesive. Animal glues are made by cooking connective tissue to turn the collagen into a gel that can be used a a glue. Properly prepared on a tight joint with enough contact area to accommodate its lower-than-wood strength, it can make strong bonds that last if it is kept cool and dry. It's still used in stringed instruments like violins, which are periodically taken apart for maintenance, and the weakness of the glue ensures clean separation. Cheap polyvinyl acetate glue like white school glue is much stronger and tougher, and a good modern wood glue like Titebond III is weatherproof and stronger still. A good epoxy can fill gaps and last indefinitely in marine or high-stress applications. Collagen is digestible by humans, let alone environmental bacteria, and it is useless in wet / outside applications, where it just disintegrates. Much of what we take for granted today was invented relatively recently.

It is not as informative as you think and has the engineers screwy view of everything as it is when new.

Modern adhesives means the wood fails instead of the joint when it does break, often times this means it is more or less garbage, almost always considerably more difficult to fix than proper joints and glue selection.

In reality most mass consumption furniture is more screw than glue, some amount of mid grade stuff is glued with no thought to the long term, high quality furniture mostly sticks to those techniques that were worked out the hard way and they tend to fail gracefully and fix easily.

Most engineers make terrible wood workers.

Rope is not good here, the fibers are twisted good and tight so you can not drive it in. Oakum is likely best, cotton next, you can get suitable stuff for caulking from places that sell boat stuff. Do a search for caulking carvel boats, it will teach you how to fill those gaps good and proper.

Depends on what you're doing. If you want no breakage or disassembly over the life of something, you use strong modern glue. Traditional glue is completely unacceptable for wooden boats or aircraft, for example, and it is far inferior for most wooden structures. Note that these are projects where an actual engineer would be involved. As I mentioned, it holds on in niche applications where tradition or the need to disassemble something later takes priority over strength and durability. Also note that "high quality" furniture of the sort you're talking about is largely a status symbol these days, so using more expensive production methods is a feature.

>> No.1512993

>>1512878
There is no such thing as 'no breakage,' generally the cause of failure is a sudden quick force, with hide the glue will give, with PVA or better the wood will give, one is easy to fix, the other is a pain and often the wood is too damaged for reliable repair.

Only disposable boats are just glued, any meant to last are a hybrid construction utilizing fibreglass or the like, you talk about niche uses and you give two of the most niche uses of wood and glue, far smaller of a niche than either instruments or quality furniture.

All cross grain glued joints will break down over time regardless of glue used, expansion and contraction over time either breaks down the glue or the wood, they will generally last about the same amount of time regardless of the glue used.

With the exception of fish glues, hide glue will be stronger than the common woods, strength is not an issue here.

Quality furniture is for anyone who sees the value of buying furniture just once instead of buying over and over. Was not aware that knowing the value of ones money was a status thing. Personally I would rather save up and buy furniture that will outlast me instead of replacing it when shoddy construction causes it to fail.

I was wrong to mistake you for an engineer, any engineer would see sense beyond status in quality well constructed furniture.

No single glue is superior, they each have their use, unfortunately many are unable to see beyond new=improved and we live in a world of disposable goods.

Not, when by "high quality" you mean something that doesnt fall apart within 5 years or smth that isnt a bloated shipboard. American Shakers built "high quality" furniture but it was nothing luxurious, just rediculously durable and well made - it was working class minimalistic in desing - everything dovetail, even the back of drawers.

They do not have anywhere near enough flex to prevent wood from breaking, they would fail as adhesives if they did. They have enough flex to make sure the glued wood fibres do not tear themselves to pieces from seasonal movement and that they can flex with the wood instead of break down when the wood flexes.

They still have to much strength for furniture, puts all the stress on the glue joint instead of spreading the stress acoss the cut joint, which is a major function of these joints that this thread seems to be over looking. Glue and screws can not spread the stress even remotely as well as proper joinery. Flex 's important, but secondary to distributing the load.

Been thinking about this, and assuming the dimensions of the pieces to be joined are the 3/4s or so of the pic then I think dovetailing with a draw bored dowel from top to bottom and wedges into the ends of the dowel would be the strongest for getting a clean corner without any glue. You would have to cut it pretty much perfectly and experiment with the drawbored pins diameter and offset to find the best size for the given woods used, but if cut well, it would last a very long time, likely outlast any glued dovetail.

The drawbored dowel pulls the joint tight and the wedges push everything together top to bottom.

I may have to try this, would need to fashion my own drawbore pin and drilling the holes for it just right would be a bitch to figure out, but it would be damn strong. Never seen such a joint executed.

Im not that familiar with drying, but why is it important for wood to be dry when working with it? In case youll make an outdoor structure that will get wet, shouldnt you work with a wood that has similar moiusture as the setting instead of room setting dried?

Also doesnt the wedged mortisse tennon put too much stress on the tennon? I know that you can break the tennon if over wedging so it might affect it when it stretches with moisture?

>In case youll make an outdoor structure that will get wet, shouldnt you work with a wood that has similar moiusture as the setting instead of room setting dried?

Yes and no, The way the wood is to be joined will dictate if you want your wood green or dry regardless of the setting. There are techniques for making indoor furniture with green wood such as the windsor chair, the drying of the wood in the finished chair makes the joints tight and long lasting despite the lack of glue, making these chairs from dried wood results in a chair which does not last as long regardless of the glue used. Conversely if you made a standard modern wooden deck with all of its screws out of wet wood it will likely start splitting when the dry season comes and the sun cooks all of its moisture out and the wood shrinks, it also means any applied finish will take forever to dry and may not cure properly at all. But we can build long lasting chairs from dry wood and long lasting decks from wet wood, we just need to take that into account in our construction techniques. In the case of the joints talked about here and what OP wants, well dried and well seasoned wood is best since these joints loosen up and loose their strength if the wood shrinks from continued moisture loss after the joint is completed.

I agree, generally speaking dried is better since most builds are done in summer or for room temperatures, but still wouldnt it be risky to use room dried wood for an outdoor project you build in rainy autumn? That way already tight joints might get tighter to the point of braking when wood starts swelling? pic kind of related

The tenon will not break from the wedges, but the sides/ends of the mortise certainly can, if it happens from wood expansion than the joint was not properly sized for the materials or not properly cut. Most common cause is the joint is brought too close to the edge of the board, next the wedges are oversized or the tapers on the ends of the mortise the that wedges displace the tenon into as they are driven, are not matched to the wedges.

Wedged mortise and tenons are not the best for outdoor items but they are used, generally you would want the wood as dry as it will ever get in the areas dry season since if this joint dries out post construction, the wedges get loose and may fall out robbing the joint of its ability to hold against any force that pulls on the tenon. Often times when you see this joint used outdoors, or any wedged joint, the wedge is left proud so it can be knocked in deeper as needed. A draw bored mortise and tenon is far more common in outdoor and green wood items, more robust and no wedge to check, but sometimes the wedge is the best option. When used outdoors both need to be sized properly to not become loose in the dry times or split in the wet, we can do it with either dry or green lumber.

It would be risky if you did not take into account the expansion of the wood in your joinery choices, just as it would be risky if you used green wood and did not take into account the shrinking of the wood as it dries, and yes even outdoor wooden objects made of green wood dry out, if they do not, they rot.

Dovetails handle expansion fine, but are only good for large timbers when used outdoors, such dovetailed log cabins. Mortise and tenon are the classic, with drawbore pins, perhaps glue as well, depends. You just need to size them properly for the conditions, leave enough wood on all sides of the motrise so expansion of the tenon can not split it. Mostly you just keep up on the maintenance, paint or oil every year, store it in a place that gets good airflow and the wood will reach an equilibrium and settle down.

You can do it with either green or dry, if you want a gentleman's sled, use dry and keep up on the maintenance, give it a good cleaning and coat of paint after it has dried out. If aesthetics are not a concern green wood will do, but you will not be able to put any drying finish on it for the first year or two so expect some splitting and checking. Mainly find a tried and true plan that you like and follow it, use the wood it says.

>how about pic rel? In summer but not entirely dried out? isnt that a kind of dovetail?

There are dovetailed log cabins, that would not be one. Log cabins just use green wood, takes far to long for such hunks of wood to dry and it is expensive to buy them dry. So you build green and let the wood dry out in their finished form, gaps open and you shove in the gunk of your choice as needed. Within a decade things are more or less dry and equilibrium is reached, gaps cease opening up.

Wood shrinks as it dries out, the windsor exploits that. The spindle ends are driven into into holes which compress them and the ends are wedged, this holds them tight as things dry, As the seat dries those holes the spindles are driven into also shrink tightening up on the spindles.

Generally the spindles are a different type of wood than the seat and the seat is a much large hunk of wood that holds its moisture through the working, the spindles are quite small and will be fairly dry by the time the chair is assembled, especially the ends which dry out the fastest. So the spindles do not shrink much and the seat does so it's hold on the spindles just increases as the wood dries.

Any wood furniture can self destruct being brought to a new climate, windsors are fairly robust, they are from the times before climate control and take most things gracefully, better than most. There is a reason the basic mechanics of the chair has not changed in over 300 years and it has remained in use and construction for that entire time. There are a fair number of cheap manufactured ones though, they are garbage and do not last long at all, rely completely on glue and are made from poorly dried wood, more windsor style than a windsor chair.

that is the trick then. thank you for your post, it was very informative.

also, is there a method in big build log cabins on determining the workable moisture not to end in castrophy? How cautious do you have to be regarding wood dryness and time of the year?

I can not see that a log is going to shrink enough to cause problems with the standard log building techniques. Traditionally you would cut your trees in the winter and build in the summer since those are the down times for that life style, so the logs have a good amount of time between cut and build, but I know of cabins that were built with freshly cut a peeled logs, they do just fine. No idea about 'big' though.

Thank you for stating it so well. I am a huge fan of getting quality over "its cheap enough" like my wife was.

Why buy deck chairs every four years when you can get 30+ years out of a quality chair at only 3x the cost?... we will save tons and we will enjoy them better.

Not rope, you need loose fibers that you can pack in, oakum, hemp, or cotton, stuffed in dry with a caulking iron and then puttied over, the putty could contain tar, pine or coal, or in a working boat be pure tar, finer vessels used a putty made up from linseed oil or the like that would not bleed through the paint work.

Not him, but that is a joint really only meant to provide strength in tension/compression, only really meant to support its own weight/forces in any other direction, keeps your roof from pushing apart your walls, but not much else.

Wood Joints In Classical Japanese Architecture

Easy to find free online, but not a very good book in the end, gives very little information on the joints use and how they work together within the structure. Mostly it gives you some decent drawings of the joints and some nice pictures showing how they fail, nothing on laying out and cutting.

Would not really recommend unless you just want something to drool over, if you actually want to put these to use there are better options, but none which you are likely to find for free.

You want something stronger than the wood itself? Bolts or lag screws.
I gotta say though there's nothing wrong with glue.
Glued finger joints are as strong as you could ever want. Structural finger-joined lumber uses phenol-resorcinol glue and is as good as an equivalent single piece of lumber for construction. In other words, with the right glue, they will withstand permanent loads.
(PVA isn't suitable as a construction adhesive where there is constant bending or tension, because PVA creeps under high sustained loads.)

>>1522119
>You want something stronger than the wood itself? Bolts or lag screws.

Bolts and lag screws weaken the wood itself and without the addition of glue weaken the joint by concentrating forces at the screws/bolts, fine when the wood is of suitable dimensions.

Do not think anyone has said there is something wrong with glue, just wanted to know how to do it without glue.

>> No.1522304

>>1509833

The strength for a given joint is dependent on what kinds of stresses it will be subjected to. There is no "best joint," only joints that are good for specific applications.

I can't find the chart that goes over the different kinds of joints to use, but it used to be posted on /diy/ all the time.

Been trying to find the title of the good book, can not remember the title and google just thinks I want what is popular, If I have time I will dig into the box of books it is in and get the title.

The Complete Japanese Joinery is alright, much like a more thorough version of Wood Joints in Classical Japanese Architecture, but still looks at each joint on its own and does not really address how they all work together.

The Genius of Japanese Carpentry: Secrets of an Ancient Craft is pretty good, I remember it being the most practical and does consider the structure as a whole and not just the joints.
