Wood Joint Strength Tests on End Joints.

Testing woodworking joint strength helps us to decide what methods might be more effective when we build things out of wood like tables, kitchen cabinets, benches, book stands any kind of project that requires some sort of framework. The end grain to end grain joint is the hardest to find a strong and effective way of wood joinery and knowing how some wood glue joint options work the best can helps us make better woodworking decisions. In this video, we'll be doing some woodworking joint tests with a hydraulic press.

That "pre-glue" result surprised me!

[BlameItOnGreg]

If you’re doing these sorts of testing type things in the future, I would highly suggest doing at least 3 of each test, so in this case if you had done 3 of each type of joint with same wood and procedures. That can’t help bring to light the variability in the test/materials, which can be surprisingly large sometimes.

Very dramatic replays! I'd always had the idea that biscuits were intended more for alignment than increased strength. Thanks Colin.

[IsaKocoglu]

*AWESOME* test! Thank you very much Colin 😊👍

[rikki]

Brilliant! Always appreciate your videos Colin!

[JamesLibrary]

Great demonstration, Colin! Thanks for sharing your findings with us.

Great video, Colin! Always a pleasure watching

[techman]

Nice practicable vid. Answered my questions nicely. Thanks.

[MrMarkpeggy]

Thanks for the great video Colin 👍 The testing gave some impressive results.

[drawengrave]

Very useful demonstration with important answers to a lot of questions.

Interesting! A few suggestions from others for a sequel. Most valuable: (1) biscuits make the butt joint weaker. Not significant on a long edge joint where there is lots of wood with biscuits spaced for alignment. (2) preglue! I didn’t see any mention of Dominos, but that would be purely academic (for most of us). I would like to see the tests repeated on the face with a caul to spread the pressure. Thanks for an interesting, informative video.

That’s very interesting. Thanks. I always enjoy your stuff and look forward to each episode

[humanityisouressence]

Thank you very much for the great information. I appreciate your effort in this wonderful educational video and wish you success and progress

[stuartscott]

Revealing demo! I will remember what you have shown. Thanks!

[mattmayes]

Very interesting data from that testing... Thanks for doing the experiment 👊👍👍

[miki]

I know you addressed this, but particularly the scarf joint strength would be interesting to see

[kenshores]

Interesting video. I would not have thought that would be what the answers would be.

[TickyMN]

How does this compare to a board that is whole?

[xianshengxu]

When the first board broke, I was scared by the sound of breaking because I didn't have psychological preparation. I hope to see more mortise and tenon tests. Thank you for your video.

Great video, Colin. I do feel you should re-test the biscuit joint.
