You are 100% correct! The friction between the boards forces glue into the pores of the wood, forcing the air out. That creates a vacuum when pulled on the boards resisting loosening. I was taught this method by my grandpa when I was 10 yrs old, it never failed me. I love it when these old techniques prove their value time and again! (62 yr old woodworker)

That’s so awesome to hear that the lessons your grandfather taught you are still being applied to your work. As a former wood shop teacher, that made me smile, my friend 🙂

Grandpa knew what he was doing.

That is fascinating. I've been woodworking for 25 years and never saw this before. Thanks for sharing this!

Love the sound of sharp fine tuned plane...

I’ve done rub joints in the past it always makes me smile and works just so well

I have been woodworking for years and never considered this. Thanks. I will use it now too.

That's great! Thanks for sharing!

I've used this a lot for gluing segments into rings for segmented bowls. Works a treat. Much faster and easier than trying to fuss with clamping odd angles.

Bravo my guy. I've always known about this technique, but rarely do I think of using it. I have a buncha boxes that I want to make soon in an attempt to use up scrap material and I feel this will significantly simplify things for me.

Very nice technique! I have done similar things in the shop without realizing that this is a known, standard approach. Love it! Thank you!

I learn something new everytime I watch one of your videos. The rub joint is going into my bag of tricks right at the top. I make a lot of thin panels right now. This is going to save me some time for sure. If you ever put together any kind of in person woodworking training/classes, I would pay handsomely.

Thank you for the video. I made my first rub joint today, and it worked wonderfully!

One of the best joints for small stuff. Stays flat too if your planing both joint edges together. Great video. Like your style. Jamie

I was taught that in school when I was 14, I am 55 now, living in the UK. It really works well on face grain too

1) Love the Chanel and the content! 2) The rub joint was a cool trick. 3) DAMN, I need to know more about that plane stop! That is the coolest little thing I have seen in a long time!

That was very cool, mate. I'm always interested to find out about how things were done in the past no matter how simple it may seem. Thanks😁👍

Love the simplicity of this joint. Can’t wait to see more of that silver maple box!

I just used that technique because I was gluing up two different thickness of wood, also some what thin, and to clamp it was proving very difficult so I glued just like you did, rubbed the edges together, laid on a flat surface, left it for an hour, came back, and darned if it didn’t work, I was feeling pretty smart about it, then I came across your video, and well, so much for being original.😂 Thanks for the video.

I think metal machinists experience a similar effect when two metal surfaces are so flat and even that they stick to each other. I think it's called wringing. People are not sure why it happens. With wood it must just be glue suction?

Struggled today to glue up two 12 mm boards, I just could not clamp them without them cupping. I'm going to try this tomorrow. Edit: after leaving the shed despondent yesterday I gave the rub joint a go. On my first attempt the boards did not stick together. Could it be something peculiar to Tasmanian silver wattle? Don't be an idiot, I say to myself, then try it with just a little more glue...AND....right there like pure magic those two boards bond together. This is going to be my go to technique for making the panel in frame and panel doors. I CAN'T THANK YOU ENOUGH! (When you used the term "bloody" I thought, has he been hanging out with Aussies? Then you mentioned crotchety old English woodworkers and it all made sense 😂).

Years ago, there was an ad for a glue "one drop holds a tonne". In the ad, an elephant (circa 5 or 6 tonnes) was in a harness with a machined metal block (with a machined surface) at the end of the lifting lines, which was glued to a similar block on a telescopic crane... yeah, the crane lifted the elephant, but (because of the machine mirror-finished surfaces on the metal) the same lift (with transverse movement preventers) could have been done using water. Physics is fun, and "nerding out", leads to new knowledge.

Your planing stop system is so nice! Might use that idea in my new workbench

Wish I'd seen this last week when I glued two thin boards together to make a box bottom. I did manage to clamp them, and I also clamped three cauls across them, all clamped down to a slab of quartz countertop. They came out flat. I had never heard of a rub joint.

i did one of these yesterday, Try using tite bond quick and thick that stuff works great.

Something else I did not know. Cheers.

Funny I seen this. I do this all the time. Never knew it had a name. I always thought the friction just made some of the glue set up faster. It definitely works.

Not a new concept, but this refresher is welcomed. As a previous responder mentioned, a test of the strength would be of interest. What did planning the face have to do with making the edge joint? Thank you for sharing. Have a great 2023 and stay safe.🙂🙂

Nothing really. I just enjoy a sharp plane 😂 a strength test would be interesting though…

You have such a pleasant style of explaining what you're doing! Why distract the listener with the jangly music track? That may work when you are just doing something, but it makes it harder to pay attention to what you are saying (which is very informative). Also, the incidental sounds of planing wood or using hand tools can be very satisfying/relaxing. Thanks for sharing your video!

I'm gonna try that in the next day or two

I was taught this is called surface tension. Like when you spill water on a table and go to pick up your glass and it kind of sticks….and that’s just water. Works great for reinforcing skirts or aprons with a corner block. Cheers

Hi, at the point when the two parts of the piece become hard to move and you stop, friction has caused heat to speed the glue set and the wood surface has absorbed much of that thin layer of glue..

Some sort of shear thickening, perhaps rheopecty. Attaching a term to it doesn't explain anything, but you then look even more cool.

The same thing happens when I flatten two very very flat whetstones together and as a result they are super difficult to separate.

Kia Ora & Good Evening from Auckland, New Zealand ...great video bro.

It's the same as putting together two mirrors, same vacuum effect, so if you have haters just laugh of them. Wood friend from Sweden ⭐⭐⭐

Always loved the rub joint. See too many people putting 100 clamps on a peice that doesn't need it 😆

Rub joint would be a great name for a rib restaurant.

Would this work for larger/thicker boards? I really want to glue up a coffee table top but I can't afford to buy the big clamps at the moment!

Where did you find those plane stops?? Did you make them?

👍👍👍👍

Brill haven't seen that one until now

I took a semesters of fluid dynamics so I should be an expert right? I’ll have to give the rub joint a try and set up a lab report to see if matches up with your hypothesis.

Clamps allow multi panel glue ups. Quicker. This is slower and for big enough panels it would be too hard to shift them back and forth to come together

Clamp it so the two top faces are either on the inside or outside of the sandwich. Unfold it like an upside-down book once finished. The inside edges of both boards (the planed surface) remain touching when unfolded and glued up. That way, the edge doesn't need to be square to the top surface, but it does still need to be flat.

@ENCurtis

Fade to face or back to back. Doesn’t much matter so long as you open them back up the same way. Any angle planed in will offset that way and the board will stay nice and flat

It's basically capilirstion. Take 2 sheets of glass and drop some water on 1 surface and press together. Now try to pull apart. It ain't coming unless you slide it

there's the rub

OR…You can rub them WITHOUT GLUE to start a fire😂

Tbh….this ‘rub joint’ isn’t a special ‘technique’, its something we all do in spreading glue and aligning pieces as a matter of course…At least I think so huh! I guess if there is someone out there has only ever slathered everything in gop and clamped it up, this might be news!

@Dirkthrustxxx

Жыл бұрын

You clearly haven't grasped the point of the video - this isn't about spreading glue in a joint, it's about using the spreading of that glue in order to create a vacuum type bond between the boards, which negates the need for clamping, while the glue dries (cures). Not sure if it was the mention "English" woodworkers that threw you, but this is one of the oldest known and therefore special techniques, because English woodworking, which traditionally only (used) uses hand tools, has been around for hundreds of years and their techniques have been passed on worldwide.
