Hi Matthias, I work as an engineer for one of the top 3 adhesive manufacturers. What you measured is the torsional shear strength of the wood glue. One interesting thing that you pointed out is that the different failure mode in each sample. You can see the "adhesive" failure when the bond between wood and glue failed leaving a clean surface. Most appeared "cohesive" meaning that the glue failed in the bulk structure leaving adhesive on both sides. The wood breakage was a substrate failure and these results are typically discarded. A factor to account for when comparing to Wood by Wright's data is that your setup includes leverage from the force applied at the end of the wood block. Also important is each glue's reliability ratings like humidity and temperature that you mentioned. More rigid glues like superglue also might not be able to and the CTE mismatch during temperature swings.

@@BenInSeattle coëfficient of thermal expansion. Most materials expand if temps go up, and contract if temps get lower. The amount of geometric change per unit of temp change is the CTE. So each material has its typical CTE. For joint strength stability it is benificial if CTEs of glue and wood are as similar as possible. If not, then temp change causes internal stresses in the joint, as there is only a small temp range where the geometries closely match. Cyclic stresses can cause microfracturing and debonding within the joint. Leads to strength loss and ultimately to failure of the joint.

Fun fact about wood gluing my late Great Uncle Ralph taught me back when I was a child: (Using plain Elmer's wood glue circa 1986) when applying wood glue, brush it on all surfaces being glued, and let it cure for about a minute, then apply a second coat quickly and then put the pieces together, the extra tack and time for the glue on the wood helps evenly penetrate the surface of all the pores in the woodgrain, also helps the glue to remain wet longer when you reapply, thus giving it a longer more even cure rate in the end, and will not "flash cure" (when the wood wicks away the moisture of the glue too fast) thus weakening the glue's bond into the wood. Moistening with water will only dilute the bonds made on the surface of the wood, so that will not work. I still have the example of this very lesson, a desk I made for college, which underwent no less than 6 moves cross country, and none of the joints have failed to date.

It also helps a lot to apply the glue, brush it onto each piece, let it sit for a minute, apply more glue, then rather than just put the pieces together, SLIDE the pieces against each other a bit until they naturally seize together, then slide them into the correct position. I don't know why, but when this sliding technique is done correctly, it makes the connection much stronger.

I use construction adhesive regularly for, well, construction. What I’ve learned is there are many different kinds for specific purposes. DAP4000 for example has very high PSI ratings for cross-joint strength. So when your subfloor expands and contracts seasonally, you don’t shear the glue off. I imagine that you used one of the glues that’s designed to withstand expansion, and so is weaker (but less brittle). The more brittle stuff might make better furniture joints

Your previous video where you experienced the bridle joint glue failures had me wondering...was it really a glue *failure*, or was it glue *starvation*? With the testing here, you just did a single face joint, which allowed getting a nice even layer of glue between the pieces before clamping. But with a bridle joint, or even more so with a box joint, you have to slide the pieces together during assembly, so it's not really an apples-to-apples comparison. I have often wondered if having a tight-fitting joint before adding glue just ends up scraping all the glue out of the joint during assembly. Your bridle joint tests where it appeared there wasn't any glue applied after they failed seemed to reinforce that theory. What might be an interesting set of tests would be to try bridle joints with varying clearances and use the same glue for each to see if the problem is that you are pushing all the glue out rather than the strength of the glue itself. And if so, what is the optimum clearance before the glue layer becomes too brittle and weak due to thickness?

Looking at your videos of the "glue failures" situations (as opposed to when the wood itself is cracking and splintering), it looks like the specific failure most of the time is in the adhesion of the glue to the wood surfaces. I would conjecture that CA glue is superior because its lower viscosity and thinner nature allows some amount of penetration into the depth of the wood, rather than just staying on the surface, thus forming more of a 3-dimensional bonding zone between the two pieces of wood. Think penetration in metal welds as an analogy. If this is indeed the case then it would be very interesting to see if macroscopically roughing up the mating surfaces, to make the bond zone thicker, could increase bond strength with some of the weaker adhesives.

Just out of interest I'd love to see a dial indicator on that structural post to see how much it flexes when your doing the tests. Obviously wouldn't impact the result but its fascinating to see how much 'solid' things actually move!

this video is awesome, I love how well documented it is. would be cool if you could do a video of different woods to see their durability as well. been wondering durability between domestic and imported birch and the refinished birch, so many options out there.

Thanks for including the dollar store adhesives in your test!

nice and interesting test!! Thanks!!would it make a difference if the test machine was pushing from other directions? for example, from the inside towards the outside (or the other way around) or along the glued piece? are glued pieces commonly stressed along these directions in usual woodwork?

At work we did some material testing and we figured that the adhesives are still curing after 1 week. We saw an increass on performance by ~20% between 24 hours and 14 Days.

I think you cleared up a mystery for me. When gorilla glue first came out, I picked some up because I had been impressed with their duct tape. I had this same experience, it bubbled up like a foam and separated the joint. A year later I mentioned this offhand to another woodworker I know, and he's where he had been using nothing but it for a year. He had no idea what I was talking about when I said it was foamed up. I was completely unaware there was a second type of gorilla glue that was not that horrible stuff. I normally quite agree with this guy so it was one of those things that stuck with me, off putting.

Gorilla is a BRAND of glue, not a type. They make Fast and Slow set Epoxys, Metal-reinforced Epoxy (aka JB-Weld), Contact Adhesives, Super Glues, a full range of glues. The bubbling stuff is Polyurethane glue, and it's also available from many other suppliers (eg: Sika). If you read the instructions, you will see that you MUST clamp that style of Polyurethane glue. You know, RTFM or the label on the bottle.

Any chance for an impact type test next? I feel like most failures of well constructed pieces are going to be sudden shock more than gradual loading

I was thinking the same. In particular, I think this is where super glue would suffer, because it's just so rigid compared to some of the other glues.

Hi Matias. Would the original titebond be very similar to Lapage glue? both are not for outdoors, right?

Great experiment and well done. I'm intrigued by your software. How did you get that sort of foreground window in which ou display the large numbers?

Do you like making those graphs as much as you like performing the tests? They are always so nice, those graphs. It's definitely a highlight of the video.

Great video mate. Very handy to know this.

I use gorilla wood glue for my guitar projects, despite much insistence that I should be using Titebond because it is so superior. I guess I'll stick to my gorilla wood glue and save the few bucks a bottle.

Matthias, great tests. Thanks! Are you going to stay with Lapage for soft woods because it’s cheaper than Tightbond?
