Friction Welding Hammers with a Lathe

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.

A Finn, with a Russian lathe, and a German toolpost design, speaking English, posting on an American website. Truly an international video.

Finally a tutorial for how to weld two hammers, I had been searching for ages

[iaadsi]

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.

“we decided to weld two hammers together. Because why not?” And thus, the birth of material science.

The YT algorithm must be working 'cause I've never seen this channel before and it's interesting as heck

"so if the hammer flies out, nobody is going to get hit"
*sticks Timo right in front of it*

This is a pretty good example of what happens when you don't change your wheel bearings

I see Timo, I upvote, simple as that. 😀

"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.

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

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

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!

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.

"Don't try this at home..."

No worries. Not everybody has a lathe the size of a pickup truck...
