What Wood Joint is Strongest? Let's Find Out!

When it comes time to join pieces of wood should you reach for a biscuit joiner, 2" screws, pocket hole jig, or is wood glue on its own just as strong. Today we're going to be testing 3/4" pine as well as 3/4" plywood and 16 different methods for joining each of those materials.

The miter joint for the strength and simplicity is the clear winner for me.

[dangkolache]

Wow, I would have guessed the miter would be about the same as a normal butt joint, but since it avoids end grain on both pieces it makes a bit of sense why it's stronger...just didnt realize it would be that different

I also appreciate the heavy influence from PF, the dude is a legend

[gharel]

I really appreciate how non-sketchy the setup you devised here is. I've watched a lot of these videos and most of them have an embarrassing test methodology.

Excellent joint shoot out. Thank you for taking the time to share!

[koyzumie]

Great work! Project farm would be proud

[FishersShop]

That was super cool. I was hoping to see if you'd do a non-glued dovetail joint. I read about how non-glued dovetails CAN be stronger than glued ones because the tails actually slide and compress when they're stressed and they get squeezed by the pins allowing for a more mechanical joint. But nobody does unglued dovetails anymore, so who cares? Great vid!

Hey dude …thanks a million for your pocket hole machine…i built it when your video first aired, probably 5 or 6 years ago…I sent you pics of it when you wanted viewers to show their builds. I’ve built so many kitchens, closets, and fixtures using that thing. I owe you big time🤙

Wasn't expecting PF Todd to make an appearance here, ha ha! Great video, quite an eye opener.

[elliottpeabody]

THAT was an amazing performance! Thank you!!

Love the ProjectFarm sounds. Both the miter and spline were joints on a 45 degree angle, and with this test, it put all of the force on the glue instead of the wood. I wonder how different the results would be if the jig was changed. Really great video.

[davidhorizon]

Good video. Very thorough and surprising.

[sapelesteve]

That was "Very Impressive" testing! Love Project Farm's YT channel. Other than how strong the spline joints are, I also love the way that they look. Nice work & thanks for putting in all of that time to do this testing! 👍👍👏👏

[Tony-Tech]

Nice job. Clearly it was a lot of work, but it was time well spent.

[ifiwooddesigns]

Saw this test on another channel and was shocked at strength of splined mitre joint. You’ve confirmed it is far superior to other joints. I’m assuming that the long grain of the spline helps strengthen it. Awesome video and would love to see more. Keep up the great work.

[namethem]

Splined miter for the win! Probably my favorite as well honestly

[timdoyon]

Great, informative video… I never would’ve guessed that a simple miter joint would fare so well. Learn something new every day!

[Iceman-gmfu]

great video. so it seems the miter is the best joint considering effort to produce/lb. which is exactly what I was looking for. thank you!

[crujones]

well paced video. thanks for the good information.

[davidmiller]

Excellent! Appreciate the effort. Your test rig looks simple, reliable, and repeatable. Good work.

[markvender]

Thank you. I was really hoping to see my favorite. A Lock Miter? I think I will try a lock miter with splines.
