Friction welding two hammers together by using just old russian manual lathe. Big thanks to my dad Timo for getting the idea and using the lathe.
We have finally got some sponsors for this channel and that's going to help a lot so if you are interested on high quality documentaries please check out the curiosity stream. I was using the service already before them reaching out to sponsor the channel and especially the different physics documentaries are really high quality.
can you put the hammers under the press to try to separate them
The price is surprisingly low! Gonna check them out for sure.

The earth is motionless and LEVEL.
I’m glad you got some sponsors. :)
A Finn, with a Russian lathe, and a German toolpost design, speaking English, posting on an American website. Truly an international video.
Welding pot?
And they do their shopping at a Swedish store 😁
@@explorer914 Yeah, but the hammer is probably made in china, So A Finn, a Russian lathe, a German toolpost design, a Chinese hammer bought in a Swedish store, speaking English, posting on an American website,,
@@MattiasMoberg13 Haha ja det är sant
@@MattiasMoberg13 ...they all walk into a bar.
We on occasion weld rods to plates this way. There are a few ways you can improve the result:
- Drill a small center hole on both faces to remove the material there. The center isn't spinning very fast so it produces no heat, only sinks it.
- If possible, add a small through hole on one of the parts to help evacuate the air pocket. We're typically welding rods to faceplates this way so we drill a 4mm hole through the plate.
- Stick the part out of the chuck jaws a bit to reduce the amount of heat the jaws sink.
- Finding the right speed. We've done 55mm rods at almost 2000 RPM on an old Czechoslovak lathe.
Even though the medium lathe they have is fairly sturdy, I wonder how it would behave with such an asymmetric, inbalanced object as the hammer while doing 2000rpm. Shaky in more ways than one. 😅 Interesting info!
@@Saareem no, it wouldn't shake at all
Rub 2 metal sticks together to make metal fire. Finnish Prometheus
lol
Dissimilar metals only
That comment is so...metal!
have u ever watched promethius? or are u playing god of war?
@@michael-dm2bv I am referring to the actual Greek Titan God of Fire named Promethius
“we decided to weld two hammers together. Because why not?” And thus, the birth of material science.
Also: “I’m not sure what we’re gonna do with this, but it’s done” aka the birth of science
@@dromd9498 one scientist says to another; “what happens if we do it the other way?” AKA the end of the world.
Finally a tutorial for how to weld two hammers, I had been searching for ages
🤣
My mate Thor asked me how to do this, now I'll show him who's worthy! 😁
"We shall use our medium sized lathe..."
Lauri walks up to a lathe the size of a school bus.
im scared enough of a regular lathe, ive seen some idiot with long sleeves and gloves get completely sucked into one
Look up a lathe thats used to machine crankshafts for ships
If you've ever seen their large lathe, you'll understand why this is the medium sized one!
"You call that a lathe?"
@@user-tr2dh4xx6uOof. I have seen that on video aswell. I dont feel very secure around lathes anymore.
The YT algorithm must be working 'cause I've never seen this channel before and it's interesting as heck
It's an amazing channel
they’ve been a youtube staple for years, you have a hell of a backlog to play in the background and look over to when you hear the loudest bang of your life
You got some binging to to do. :D
These folks are addictive so watch out!
I've never seen anymore more interesting than heck
This piece of art belongs in a museum
that would be my kind of museum
It's much better than a bucket of shit or a banana duct taped to a wall, I'll tell you that much.
This is a pretty good example of what happens when you don't change your wheel bearings
"This is going to be a great success, do you know why? Because I have planned this." Timo is awesome! I need some of that confidence.
Timo is obviously a legend - a master of "Sketchy" plans.
I love this channel :)
I always thought your father must be annoyed by all the experiments in the workshop, but I think he just enjoys them as much as we all do. Cool video!
I see Timo, I upvote, simple as that. 😀
TImo had a really good idea this time
@Peter Rabbit Some day he will!
@rod rod I think everyone thought he was much older.. great fun channel..👍🇮🇪☘️
@Peter Rabbit i always thought he sounded like goldmember from austin powers😅
Your Dad was the most important part of all this.
Never stand in the Plane of Death. :)
Thats´s the one of the first things that I have learned about lathes :D
@@Beyondthepress True for almost EVERY power tool.
U got a picture in ur name :O
@@Electroneer0 It's a Channel Member icon/badge.
@@Beyondthepress that and no baggy clothes!
Staying out of the "plane of death" does sound like a pretty good idea...
“I don’t know what this is, but we did it” kind of describes the channel in a nutshell 😂😂 (and that’s exactly why I subscribed ;p)
So I take that Timo is now the one who comes up with the deadly contraptions nobody would have dared to imagine before.
Name the two hammers: "Unstoppable" and "Unmovable".
Then tell people this happened when you touched them together.
"No cover gas or protection gas needed. " Very good point. No contaminates getting in.
Does it have equal thermal stress ?
Yes, I felt the jaws of the chuck pulled heat from the turning hammer.
That was cool.
The original method of friction welding was invented in mid-70s at the Institute of Hydrodynamics of Siberian Branch of the Academy of Sciences of the USSR by the genius inventor, lathe machinist George Fedoseev. I knew him personally! He welded everything with anything using this method. He showed me a pice of copper welded with a piece of oakwood in such a way that the joint did not fail while the copper got bent and the oak part broke. He had solved the primary issue of such kind of welding: the gradual reduction of speed between parts. His back support jig allowed to release the second part and let it instantly rotate along with the part in the chuck.
Another trivia fact: George had suggested a method of making Rubiks cube _using only lathe machine!_ I made one in early 90s and it worked like a charm.
We contracted George to make copper mirrors for our laser project and he managed to create parabolic-concave mirrors with approximate radius of curvature of 5 meters _WITHOUT CNC_ and those mirrors did not require polishing after his machining! True genius.
Thank you for reminding me of him. Cheers!
This is beautiful. You all have amazing ideas and energy.
I repaired and put into service a very old American pipe friction welder. Very satisfying watching it weld the first time with the double bead.
Very Good! But then any video with Timo in it will always be Very Good! When do we get Timo fishing live stream?
I think we are going to do fishing stream to Anni's channel pretty soon ;D
@@Beyondthepress That will be Prrritti Guud.
You’re lucky to have an awesome dad, I miss mine 😢
I know Timo does not speak much English but I would love to see a video where you interview him. He seems very cool and I would to know more! I agree with others, he is the original mad scientist!
The camera angle on the plane of death was really exhilarating 👍
Every time I see Timo have an idea or trick, I understand more about why there is a HPC.. great fun guys
6:30 "It's a double hammer."
"What do you mean?"
"It's a hammer for two people."
"But... why?"
"For when two people want to hammer the same nail, duh. Have you been living under a rock?"
It's great to see Timo again. Great video. Thanks
You guys are awesome, always learn something new from your videos, thanks for all the hard work and effort you put into making these videos👍🏼😎
I love everything about this channel, the Accents, the people, and the crazy stuff that they do. Keep up the dangerous work.
Coronahammer!!!! Timo is metal AF 🤘🏻, now the back of two straight axes to make a double headed axe that would be something else!
That's the best "how to" weld 2 hammers together, instructional video i have ever seen
I wonder how you could possibly break them apart. If only you had some kind of hydraulic press, or something... 😅
Fantastic! I am going to take a real good look at Curiosity stream. What you showed has me interested. Congrats on getting a sponsor!
Whoa! This is a thing that makes sense, and I never considered it in my life until you showed me.
Thank you!
The plane of death, my favourite part of geometry classes
It looked like the hammer faces were not ground flat first, so just a little surface was touching at the start. This must have taken forever!
Fun experiment.
Too much preparing is not the way BTP does things... Some things are planned for long, but not prepared.
Man we are simple creatures. "Yeah I'll watch two hammers rub together for 9 minutes"
Wow! It’s great to see you back in the workshop! 👍🏼
You just know some machinist is out there right now wondering how their hammers got stuck together 🤣🤣🤣🤣
Nice to see Timo involved in video.
Anni I love your pink ear safety blobs! 🥰
"I'm not sure what we're going to do with it now..."
CRUSH IT!
Double handed hammer 5000, for those jobs you need done in double speed.... Nice!!!!
"Our _medium-sized_ lathe"
God I love this channel... really good at making me jealous sometimes though haha.
Also I love how you guys are like somewhere between 8000 and 9000 km away from me and obviously have a different accent but your English vocabulary is pretty much identical to mine. Like we'd probably get kicked out of a church in Kansas or other shitholes like that, eh?
It's Hammer Time!
Fun idea MR. Timo! GJ.
Reminds me of when I was sent with an NCO in my shop to change a C-130 strut. I reckon the contact points of the strut's axle weren't properly serviced, but I never read the final report, if there was one. However, when we removed the wheel, tire, and brakes, not only had some component disintegrated (there were metal shavings all over the wheel, inside the axle, and the wheel itself looked like a grinder was taken to its face in a circular motion), we found the spacer for the brakes had welded itself onto the face of the strut. It was very interesting. We did our job and finished ops checks by the time the other crew chiefs knocked that spacer into 4 pieces and took it off.
So glad a TH-camr finally did this
ahahah social distancing corona hammer! great stuff!
Timo videos are always my favorite!
Rotary Friction Welding, invented by Russia about 1910, and Timo trying it a Russian lathe.
Prity gud result.👍.
Thanks for sharing.
MORE TIMO!!!!!!! Your dad is awesome!
The organization where I work, manufactures friction welded pistons. It's really a neat process.
Nice. Love to see a CT scan of the weld to see just how stuck it got.
You had me at ‘plane of death’…
Also, this is the first time I have seen Anni’s face clearly! She is really pretty! You are a lucky man!
"Don't try this at home"
Bro I don't even own two hammers let alone a giant finnish lathe
Russian lathe because because it needs to be very stronk.
Only you guys could make an interesting video about sticking two hammers together!
We knew this would work because when high performance machinery has bearing failures and similar catastrophic failures the rotary components will friction weld into the stationary components
Next up: Friction weld two submarines together. :)
Dad an son projects . are the best. good job .
I remember seeing some excellent video of locomotive axles/wheels being friction welded together and friction stir welding is also used on spacecraft!!! Think Smarter Every Day got a tour of a factory where it's done.
I don't know why this is so funny. This was fantastic. Thank you all
i used to do this at a metal shop. supper sweet to watch we spun at 3000 rpm and slammed the piece to the one on the lathe.
And, that is why you keep the oil and filter in your engine up-to-date!
That awesome there is a series on just how electricity was "invented". I always discover new things about this that blows my mind. Did you know that the guy that designed the CSS Hunley actually had original blueprints for it to be the worlds first electric submarine?? The original sub was going to be longer to have space to house the batteries and electric motor. When I was reading this story, I didnt even know they had access to batteries in the 1860s. When the civil war started and the CSA navy found of someone was making a submarine in the south, they seized it and told the engineer to just hurry things along and dont worry about the electric power. Had this been better funded and more resources poured into it and the southern officers didnt have to worry about keeping it a secret, the world could have had electric submarines in the 1860s, probably even electric/steam hybrid vehicles.
hahahaha I like his confidence in saying it will work because he planned it !
Timo off screen whispers to the fused hammer.... “Whosoever holds this hammer, if they be worthy, shall possess the power of Thor.”
Timo is Odin, Lauri is thor. Think Lauri would be happy with that, though he is lacking in the hair department to look like Thor
I wonder if just for the sake of it, Lauri will make a video of how to do Thor wig BTP style...
That lathe is enormous
'I'm not sure what we are going to do with this... But it's done.'.
Words to live by
I would try this again but with a thick-walled Pipe/Tubing. It should weld much faster and with better penetration.
I think the Chuck is also a huge Heat Sink which removes heat to fast while trying to friction weld the hammers together.
So I hope you will give it a try with some tubing to see how well that works.
“Don’t try this at home.” Woo... that was close! Powering down the gigantic lathe I have in my house down right now. Keep it in the guest bedroom. Love the stuff you guys come up with.
*medium sized
@@kevinpham8693 That was medium sized???? I’m going to need a bigger house.
Ima get that curiosity streaming service exactly what I’m looking for 🙏🏽🔥🔥
Now this is a different video. I like it!
Looks like a wonderful hammer for an Ambidextrous Blacksmith! Good stuff Mate.
John, Australia.
A perfect example of hammer forging
This was a really cool idea
I actually found the curiosity App on my Samsung TV. It is an absolute steal at the price they’re offering.
Nice one with the sponsor! I'm actually interested in the electricity series! And the price is peanuts! Also nice vid on friction welding. Maybe try with something else and test the strength / breaking point somehow?
That's a piece of art now.
You should do this again - so you can place them into a press and see if the hammer bends or it breaks at your friction weld.
I first learned of “Friction Stir Welding” with the development of the Airbus A380 airliner in which they were joining large body panels together using Friction Stir Welding. A lot of aerospace companies are using this method.
This is not the same technique. FSW uses a tool with a nib that physically stirs the two metals together without significant heating, it's purely a physical process. This is more commonly called spin welding and uses the friction of the mating parts to heat the metals to a temperature where they bond.
I've watched 20 seconds and I love you guys!
You two are fantastic!!!
Instant Subscribed!!!!
This is their second channel where they do random things :D
You might also wanna check the main crushing channel.
that could make really cool handlebars for some bicycle!
try it again with a copper sleeve around the two ends you're attempting to mate together...will keep them aligned better and will also cool it quicker once it has reached critical temperature
"We are going to stay out of this plane of death." Best phrase I've heard in a long time. Possibly stealing.
It's nice to watch the 3 of you do these videos together. Say where is Mrs Timo? Also if you had a tailstock or tool post fixture that would let the hammer spin once the weld was hot enough help? Instead of waiting for the chuck to slow down?
Congratulations! It worked!
TIMO ROCKS!!!!! Thanks TIMO!!
This guys just makes my day
I think real friction welders use several thousand rpm and a few tons of force (to where the metal deforms when hot and needs ground off when done welding and cooling off). Does it in about 5 seconds.
Love this channel! Thanks for the most interesting content on the Tube.
As far as I understand, friction welding needs a lot of speed to create enough heat and the higher pressure to weld is only used in the end when already glowing hot
I like how this dude sounds italian sometimes. "I don't want to break these two spicy meat hammers!"
That is just awesome. Well done.
Maximum speed light pressure it’s pretty easy to do if you have a big enough lathe just remember to not stop until it’s glowing yellow
Subscribed and following! Fantastic news on sponsorships!
More Timo!
