One of the main advantages of morris and tenon joinery was before glue was commonly used. A mortise and tenon can be pegged and will be quite strong with no glue at all. Try that with the other joints.

a lutherie trick: it's better to have slightly rough surfaces in the contact/glue area, especially with woods that are difficult to joint (due to their high oil content). It does not hurt to make small "scratches" in the areas before joining, especially on processed boards (mdf, plywood, etc)

If you are concerned about dry-squeeze then yes. Otherwise there is nothing to be gained with ordinary electrochemical glues as the wood is aready the weakest link. Any thickness above minimum will decrease the strength of the glue part of the joint. For glues that rely on mechanical tack (plastics typically) it is advantageous.
@JohnDlugosz
@JohnDlugosz Ай бұрын
I disagree. Regular wood glue is not gap-filling, and you get the strongest bond with _smooth_ faces in perfect contact with each other. That's why we have jointers. With your technique, you should use certain types of construction adhesive (e.g. Liquid Nails) or epoxy with fillers appropriate to the gap size.

Mortise and Tenon joints were considered the "strongest" for a reason - they last. Lap-joints certainly are stronger but in general they will fail earlier as they are fully reliant (in most configurations) on the strength of the glue. So when seasonal changes in temperature and humidity slowly degrade the glue the Lap-join will just fall apart. Where as the Mortise will still hold together decently even without any glue. Mortise is also stronger against loads in other directions. But the joints that are nearly always the weakest are the butt- and miter-joint. They are just inherently weaker as they do not have a mechanical locking nor a lot of surface nor continuous grain. Of course to everything there are exceptions. If you have something like say a house-frame then one of the best ways to connect a horizontal top-plate to the vertical struts is just ... laying it flat on top - a butt joint. For the loads it will have to withstand this is just the strongest it can get.

And bridle joint is my favourite anyways (together with simple lap-joints). But for both - they will not just fall apart as easily as a lap-joint, but for the bridle it really depends on the load it experiences: Pulling apart or rotating out? Doesn't fair much better once the glue is broken.

Great comment. Years ago I made a garden gate out of 2x4s. (Not pressure treated).. Each corner was a wedged mortise and tennon and I added a diagonal brace that I dovetailed into place. I only used glue to "hold it together ".. the glue failed in the first season or two but that cheesey little gate stayed together and functioning for years till it rotted to pieces.

I appreciate that you hit on the gripe I have about all of these "OMG STRONGEST JOINT" videos, going back to Matthias' seminal video. Use a joint that's strong enough, meets the aesthetics of what you're making, and will last the desired lifespan of the part. I see no problem with some pocket screws and plywood for workbench drawers, but I wouldn't use it for (hopefully) heirloom furniture. There's no one size fits all joinery and that's part of the fun ;)

I think its misleading to say that the bridle and half lap are stronger than the mortise and tenon. They are stronger for a force coming from that specific direction, but a mortise and tenon would do better resisting forces from other directions. Joints are held together by glue strength and mechanical interference and the way you are testing these joints puts the half lap and bridle in the best situation, where they have both the advantage of large glue surface area and mechanical interference. If you were put a force in the opposite direction (pressing down of the levered parted of the joint instead of up) you would lose the mechanical interference and just rely on the glue strength. In fact in the six possible directions (up, down, left, right, towards, away) the half lap only has mechanical interference in two directions (up and towards), a bridle has mechanical interference in three directions (up, towards and away) and a mortise and tenon has mechanical interference in 5 (up, down, towards, away and left). If you put a dowel in your mortise and tenon it has mechanical interference in all six directions. This is why it is a joint you can use even without glue and why it is so popular for pieces of furniture which will experience forces from several different directions. Obviously the bridle and half lap have their place and they will likely stand up fine in a piece of furniture, but you shouldn't think of them as a 1-to-1 improvement over a mortise and tenon.

They also aren’t directly interchangeable. You can’t use all these things in every situation. Sure I guess if you’re making picture frames you have all these options but when you’re making furniture I fail to see how half laps should be used to make table bases, for example. Maybe I’m not that creative or maybe it’s because m&t is simply the right overall choice in that application.

I recently read something about gluing end grain that is claimed to make it much stronger. The issue with gluing the end grain is that the end grain behaves like a glue sponge and wicks the glue down into the wood and away from the joint, with the result is that critical thin glue layer might not be continuous across the entire joint surface, resulting in a weak joint. The solution offered was to let the end grain soak up as much glue as it wants, and then apply additional glue! To do this, slather glue to the piece with end grain and allow it to sit for 5-10 minutes (but not so long that it starts to dry and set). Then apply additional glue and clamp the joint. This should saturate the end grain with glue so the additional glue stays in the joint space rather than being wicked down into the end grain. I would be very curious if you have heard of this, if you have tried it, and, of course, if it actually makes the joint any stronger.

Try a quick double glue application. I glued some red oak with an end grain glue up, as you know, oak is so straight grained porous you can stick an end in water and blow bubbles. I applied glue, let it wick into the grain, applied again, creating a micro "finger joint" with the glue. As glue is typically stronger than wood, the joint is amazingly strong. Try it for fun. I've found the more the glue wicks into the wood, the stronger the butt joint, the caveat being to make sure the second glue application takes place when the first is still tacky. fun experiment.

Great job Scott! Interesting results. I know a preponderance of woodworkers focus on joint strength, but is that because we are only seeing the amateur woodworker side on YT? What about the professional woodworker perspective? The TIME == $$ perspective. Do I really need my drawer joints to support 500 lbs of force? What about a utility curve perspective? Time/effort vs strength or another way to say it would be how fast/cheap can I make the joint that's good enough for the purpose? Looking forward the 2nd part video! (the new shop looks great!)

A while ago i started using half-lap joints in typical 2x4 construction and it's amazing just how much stronger things became. Even without glue (just screws) everything is way more rigid since in something like a T shape (and to an extent a regular 90) the end of one board is kept from splitting by the board it's cut into. I use a radial arm saw with a small dado stack in it since boards are often too big to be safely shaped on a table saw.

Hey Scott, thanks for doing this test. Really solid methodology and I always appreciate these tests that challenge conventional methods. Could you say a bit about your clamping technique for the the mortise and tenon joint? Clearly one has to clamp the half lap joint with pressure perpendicular to the faces, but I'm wondering if you used clamps in that way for the M&T. Since the glue is providing the strength of these joints, clamping pressure is theoretically hugely important.

Thanks for these awesome videos. I’m trying to build a fairly basic shelf, except I need it to fit inside of a closet with a small door, so I need to be able to assemble (and hopefully disassemble it when needed) easily inside the closet. Also, I have limited tools, I do have a miter saw, a circular power saw, some chisels that I’m terrible at using. I’m considering getting a router, as they are fairly affordable and don’t take up much storage space, not sure what bits I’d need (and bits seem pricey). I’m trying to avoid buying a table saw, as I don’t have the space for it, and do as few cuts as possible, so I’ll be getting pre-cut 2x4s for the legs (I think) and pre-cut shelves (48x15.75). Since I want it to be easy to assemble and disassemble, I’m trying to avoid screws and angle brackets as much as I can. I’ve been researching wood joints. Thinking something like a half lap or dovetail to prevent the frame that would hold the shelf from sliding in or out of the legs. Also considering trying to do dadoes in the main legs for the shelves to go into, but I’d still need something to make the whole thing stay together, and to stop the shelves from sliding out. Or maybe just a mortise & tenon with some soft of a peg, to stop it from sliding out for the long way part of the frame, and maybe halved lap joint for the short way to hold it all together. Hopefully this makes sense, any suggestions for joints and tools needed?

3:55 The miter was 2.4 times stronger than the butt. Most of this difference could be explained by the miter joint being 41% longer (=sqrt 2) than a butt joint. Beam bending strength increases with the cube of the beam height. 1.41^3 = 2.7 I suppose the difference could be in the end-edge grain difference and whether the outside corner buckled.

I love the look of the bridle and half lap but the mortise and tenon has another longevity benefit that might not ever actually matter, but m&t holds together on the ends when other joints might pull away from humidity. that's because the m&t has that enclosed wood framing.

How about the most maligned joint the pocket screw? For case work more than strong enough and quick and easy. I was a little surprised by the strength differences. Thank You

An important point: the solidity of an assembly depend of the proportions: so, if you try with a thicker miter, or if you have a thicker tenon it will be stronger. As you see, the sides of the mortises are 2/3 and tenon is 1/3. The miter you used was perhaps only 1/5 or less. Even, that's widely strong enough to build a furniture.

I wish you showed the breaking in more detail. You have two fundamentally different types of failure: The glue, or somewhere that's not the joined surface. Your first miter joint was interesting in that it opened up gradually as you increased the force, rather than breaking suddenly. Your lap joint broke elsewhere, meaning the glue was the strongest part. The bridle joint improved the strength because you had grain going in two directions at right angles, like plywood. This makes it more difficult to pull the fibers apart in one of the legs. Also, note that you can make a lap joint that looks like a miter, on one side.

Reason you were getting crazy numbers on the box joint was due to the jack being so close to the joint. Double the distance from the jack to the joint, and will break at 1/2 the force. It's like using a torque wrench, longer the handle, the easier it is to turn.

If you're not painting the cabinets (in which case you'd be looking at a lot of painted endgrain whenever you opened a door), and if the client isn't averse to some endgrain in their door joinery, the bridle makes for a highly attractive joint. I know I sent hundreds of such doors (meaning thousands of such joints) out into the world, where they would last a few centuries in the unlikely event they don't get scrapped in about ten years time, which is about as long as kitchens survive before the next remodel, in the U.S at least. Sort of sad to think about it like that. Then there's the thousands of handcut dovetails in the drawers… _Fine Woodworking_ magazine did this test a few years ago (I think they may do it periodically), and I recall the bridle proved to be the strongest. I did a more informal test on my bridle joints: I glued together a rail and stile, stood the stile upright on the floor, and then made a seat of the rail by putting virtually all my weight on the distal end. When the joint didn't budge it was good enough for me.

Isn't the difference between butt and miter joint just due to angle of attack when trying to break it + lenght of glued area being 41% larger?

A nice test of the common flat joints. Since I make a lot of boxes, I'm looking forward to your upright joint tests. Though I will say that since I'm not making wooden strongboxes, I still mostly use the easier to construct splined half-lap upright joints for the corners. Yes, I'm sure finger joints (which I think are ugly) and dovetail joints (way cool, but with high skill & time requirements) are stronger, the modest half-lap, reinforced with structural AND decorative splines, is strong enough for my use. It's also easy to cut rabbets along the top and bottom edges of the side pieces for the inserted lid and bottom. richard -- “Everything that needs to be said has already been said.

Following your conclusion about the lap joint leads me wondering if I should have used a version of that for the Shaker entry table I just made for my wife. Being a novice, I struggled to make good mortis and tenon joints. They'll hold together and look fine from the outside, but I sure ain't proud of the quality- it ended up being a hack job. Seeing this video makes me realize I might have been able to use a lap joint to join the apron to the leg (from the inside of the leg), especially since I was going to add corner blocks anyway. (sigh) Any thoughts on that? Thanks!

This is a glue strength test showing results based on surface area, more surface area more strength. Assemble all these joints using wooden dowel or wedges etc that would be a better way to show joint strength. These results would be different using different glue types.

Not all joints are equal, but "by how much" is tricky to tell. The tests I see treat the joint as a monolithic structure. In fact, it is composed of many micro-elements. So when the splined miter is tested in a mode (compression, or pushing the two ends together; vs. tension, pulling the two ends apart), you have to examine the elements. External compression of a joint creates both compression and tension in the wood; likewise, tension test of a joint also creates both tension and compression elements in the wood, but the locations are different (of course). The role of the spline changes depending on whether the wood at the spline is in tension or compression. A spline doesn't help much when it's in compression; but when in tension, the spline can enlarge the stress area, allowing more stress before failure. The joint is not uniform in its strength direction, and most testing only operates in a single direction, which makes simple conclusions very difficult.

The major difference between butt joints and miters is that end grain allows much greater surface area due to the channels naturally present to accept glue in the end grain, as opposed to the negligible spaces in the surface of the flat of the board.
