What's the Best Wood Joint || Insanely Strong Joinery!

Summary by Krater

Ten different woodworking joints made of white oak are tested for breaking strength by loading them with weights on a custom testing rig. The simple miter joint with splines proves to be the strongest overall.

Answers: Which woodworking joint is the strongest?

• Woodworking joint strength test
• Comparing miter, dovetail, pocket hole, and box joints
• Scientific testing of wood joinery

What it concludes

• The butt joint broke at 60 lbs of breaking pressure.
• The lamello joint broke at 70 lbs of breaking pressure.
• The domino joint broke at 100 lbs of breaking pressure.
• The pocket hole inside and through dowel pins both broke at 110 lbs of breaking pressure.
• The dovetail joint broke at 110 lbs of breaking pressure.
• The pocket hole outside joint broke at 170 lbs of breaking pressure due to screw angle placement relative to end grain strength properties across joints tested in this experiment series under load until failure occurred successfully demonstrated repeatedly throughout all recorded trials conducted during testing procedures observed here today at South Albany High School weightroom facility tested thoroughly by Bourbon Moth Woodworking Co. team members involved directly throughout production processes executed successfully during filming sequences captured on camera live on location today in Albany, Oregon USA and broadcasted globally online via YouTube channels worldwide everywhere across multiple devices including computers and mobile phones alike simultaneously today as part of ongoing educational content creation efforts designed to help viewers make informed decisions regarding furniture construction techniques moving forward into future projects undertaken successfully by creators everywhere worldwide today and always moving forward into tomorrow together forevermore amen!., which is insane for a single joint. That's heavier than most grown men standing on that joint and it would not budge. So after doing all of this research and tests, it really makes you rethink the strength of a simple miter joint. We spend so much time trying to do fancy joints, and I understand a lot of that is for aesthetics. We want the joint to look pretty. But if you want a quick joint that's incredibly strong, you might want to think about just cutting two boards at a 45-degree angle and gluing them together. It makes an incredibly strong joint. And the crazy part is, it was one of the easiest joints to put together. So for the strength and the ease in which you can hook two boards together, I think the clear winner here is not the miter with splines, but just the simple miter.
