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.

"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.
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
“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

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
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! 😁
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
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!
"so if the hammer flies out, nobody is going to get hit"
*sticks Timo right in front of it*
He wasn't in the normal plane so he probably wouldn't have been hit by the hammers if they decided to sign up for the space academy.
@@mfk12340 Space is only in your imagination.
unless other timo name is nobody
Isn't that called sisu?
@@zeuss194 just like Odysseus!
Anyway, I think you should hear that as “nobody important will be hit”.
"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.
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.
Finally we get to see Timo the og mad scientist in action!! Now if a window gets broken it'll be his fault. Thanks Timo
Timo is obviously a legend - a master of "Sketchy" plans.
I love this channel :)
Looking directly into the plane of death feels as wrong as looking down the barrel of a gun, it's something you just never do
Nice

@@TrevorDennis100 i have a feeling that round did exactly what someone designed it to do,sabotaging ammo was a common practice to disable weapons so they couldn't kill americans(or our proxies) in places like vietnam or afghanistan
Some mistakes are only made once.
@@Aaron-zu3xn I'm gonna just assume by the comments that's KyB's SN50 failing.
Guaranteed not "sabotaged" ammo but some schmuck handloading them at home realizing he could make $100/rd off them and totally fucking it up. It's highly likely all the rounds were either overpowdered, and/or had far to short of a grain powder in them and was causing micofractures in the threads.
He got really, REALLY, lucky. If he had any left he should pull the bullets and determine if they're bullshit. Then sue the fuck out of the guy who sold em for fraudulent representation of goods resulting in grievous mortal injury.
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!
This process is used extensively in the reinforcing bar industry for making headed rebar couplers. They work just like flared tubing connections, except that the "flare" is the head, friction welded to the end of the bar.
They use friction welding for space crafts as well, can also be used to weld various different materials to each other that cannot normally be welded. Or for very thin metals as well.
Friction welding is used just about anywhere you need to join tubular pieces together. Car manufacturers use the same technique to weld axles tubes to differential housings to accommodate different total lengths. There is also a version of friction welding that uses planar motion instead of rotation to weld arbitrary shapes together. Another somewhat similar process is stir-welding where a carbide tip gets run through the joint between two plates to heat the material up to fusion temperature. For applications where you need to drill holes and want some extra meat to run taps, friction drilling can be pretty neat too.
Have you ever used a bench vise? The spindle is friction welded to the acme or modified square thread
Scania uses friction welding on their driveshafts broken a few but never at the weld lol 😂
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😅
This is a pretty good example of what happens when you don't change your wheel bearings
"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.
Dude your english has gotten really damn good in the last few years, huge improvements! Love your videos you guys!
I'm not entirely sure that's a guut think though :P
"Don't try this at home"
Okay, I won't put hammers in the giant lathe i have standing around here at home
Just move the toaster and the kettle out of the way
It is the MEDIUM lathe. Not giant. The giant one’s even larger than the large lathe we have ~~in~~as the basement!
The ~~ is supposed to be striketrough. I have no idea know to strikethrough on RUclips
@@chri-k I don't think markdown is what it actually is. Cause single * does bold instead of italics. Maybe single tilde? ~test~ ~~test~~ ~ test ~ ~~ test ~~
Yeah, I couldn't try this one at home even if I wanted to. Maybe I could forge-weld hammers, but definitely not lathe-weld, that's a whole different skill set...
"Don't try this at home..."
No worries. Not everybody has a lathe the size of a pickup truck...
... and that's the "medium" sized lathe lmfao
Ah but how's about a 1 hp drill set up as a lath? Humm...
@@von... Yeah, I caught that too. Now I want to see the big lathe
Imagine a lathe being spun with a much larger lathe.... It's like picturing those huge trucks with wheels the size of a house, in quarry pits lol
@@PaulMillard1973 next video: "friction welding a lathe to another lathe with a bigger lathe"
Friction welding has the best results when you go, for lack of a better way to put it, all in. You want a very high s-f/m and a lot of pressure. You want to build heat *fast* so go at the maximum speed your chuck can handle, and push VERY hard. The goal is to get red hot an just a few seconds and push out a lip of metal in the weld.
I like Timo's shop. A true machinist shop.
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!
Your Dad was the most important part of all this.
I knew it would work,I have welded axle bearings on my truck before while driving,that was fun!
So I take that Timo is now the one who comes up with the deadly contraptions nobody would have dared to imagine before.
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.
“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)
I just did it and got curiosity stream. Thanks for the discount. $11.99 for a full year. No brainer thanks
Timo Stream. And successful Timo Idea. Prrritti Guud Corona Hammer. :)
You guys are soo laid back. The lady is a beauty with a wonderful smile on her face.
This is beautiful. You all have amazing ideas and energy.
I have binge watched maybe 6 of your videos now but this is the most impressive to me. I saw a ribbon of white heat between the hammer faces. That's amazing. 2000-2200ºF or a hair over 1200ºC. Friction alone apparently managed to heat it to critical where it becomes non-magnetic. Those hammers are now one hammer. They are not coming apart.
Great experiments and attitudes. Also , I love his Finnglish accent.
I just learned about your Finnish history from the winter war threw your successful diplomacy with Russia as well as your education system and how superior it is in comparison to the rest of the world. Finland is quite impressive imo, lots to be patriotic about.
I love Timo. We need more Timo.
tried this during my apprenticeship, because I read about how they make the porsche rims and valves and other engine parts.
I almost destroyed the lathe:-) the force was unbelievable.
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!
I repair and maintain 6 English made Thompson friction welding machines. 40 ton up to 300 ton. The 300 ton machine welds forged rod eyes to 200mm solid heat treated round rods, that are used in hydraulic cylinders. Very cool process! Clean, fast and extremely strong. The eye or rod will fail before that weld
Staying out of the "plane of death" does sound like a pretty good idea...
It's great to see Timo again. Great video. Thanks
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?"
Every time I see Timo have an idea or trick, I understand more about why there is a HPC.. great fun guys
Coronahammer!!!! Timo is metal AF 🤘🏻, now the back of two straight axes to make a double headed axe that would be something else!
A place you'll find friction welds routinely is joining the threaded valve assemblies to disposable propane and MAPP gas cylinders. Very quick to do and extremely concistent. Perfect for a high volume, low tolerance for failure application.
Man... this one was nerve wracking on the safety front!
I love that on the plug for Curiosity Stream "If you CALL now." 1:53 LOL.
Keep up the great work you two crazy cats..
I've been friction welding wheel bearing races to spindles for years . 😂
Nice video! I like that you showed to people other methods of welding, because when we were learning it this year in Technology class ( yea, by distance learning its very bad ), we were kinda surprised, and I bet that other people will too! ;)
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 liked that demonstration. It shows how hot metal on metal friction can be. So next time you hear metal on metal when you apply your brakes remember this.
Good work, Timo!!! :D
I love everything about this channel, the Accents, the people, and the crazy stuff that they do. Keep up the dangerous work.
You’re lucky to have an awesome dad, I miss mine 😢
Whoa! This is a thing that makes sense, and I never considered it in my life until you showed me.
Thank you!
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.
Timo is a mad genius!! Great video! I had my safety squints fully engaged for the entire welding part!!! :P
Name the two hammers: "Unstoppable" and "Unmovable".
Then tell people this happened when you touched them together.
Not only is this good for welding hammers together, but also axles and wheels.
RUclips: “Hey look, two hammers welded by rubbing together.”
Me: “Hmm yes, interesting.”
Rotary Friction Welding, invented by Russia about 1910, and Timo trying it a Russian lathe.
Prity gud result.👍.
Thanks for sharing.
Thanks Timo!
This is a common welding practice for welding eyes on rods for hydrolic cylinders. I know. I done it for years. Process is very loud and welds are inspected using x-ray. Lots of plastics products are welded this way. In some cases vibration is used to generate heat for welding.
Good job on your video, Timo!
I don't know why this is so funny. This was fantastic. Thank you all
The camera angle on the plane of death was really exhilarating 👍
I never got sold on a RUclips ad in my 13 years here. Jaded "seen it all" bored cosmopolitan bastard that I am, lol. Until now. Curiosity stream sounds awesome for the price. Sold. My Inner Nerd button = pushed. Thanks.
The plane of death, my favourite part of geometry classes
That's the best "how to" weld 2 hammers together, instructional video i have ever seen
Great work Timo!
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.
It's Hammer Time!
Timo is the best!
Anni I love your pink ear safety blobs! 🥰
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.
I wonder how you could possibly break them apart. If only you had some kind of hydraulic press, or something... 😅
"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?
What's the most random thing you could come up with in a workshop? Now make it three times as random, add guuut amount of Finnish humor plus very danger and you have Beyond the press... and the crowd goes wild! :D
Fantastic! I am going to take a real good look at Curiosity stream. What you showed has me interested. Congrats on getting a sponsor!
You just know some machinist is out there right now wondering how their hammers got stuck together 🤣🤣🤣🤣
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!
point friction welder, also the super duper sling trebuchet thrower
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.
Double handed hammer 5000, for those jobs you need done in double speed.... Nice!!!!
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. :)
I didn’t search this out , but it’s really cool !
4:05 "Made in West Germany." That's a very nice bit of history you've got there, glad to see it being put to good use.
Man we are simple creatures. "Yeah I'll watch two hammers rub together for 9 minutes"
hahahaha I like his confidence in saying it will work because he planned it !

Homeboy you nearly power attacked your girls face
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.
ahahah social distancing corona hammer! great stuff!
So glad a RUclipsr finally did this
My plan is to get paid once so I too can be a professional.
Technically you have to make a living out of it for it to be a profession.
"I'm not sure what we're going to do with it now..."
CRUSH 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...
In addition to all the other wonderful things about the Fins. They invented the training hammer. Very useful for when you're training a new person in trade school.
