Dead blow hammer
Two hammers are dropped at the same time, one bounces up and down continuously, while the other hardly oscillates. This seemingly magical hammer is called a dead blow hammer.
Cutting open this special hammer, we can see inside there are many small iron balls or sometimes layers of steel coins stacked on top of each other. They are placed inside the hammer head in just the right amount and leave an empty space inside. When the hammer is struck down and collides with a hard surface, these internal components falling down will create a force counteracting the recoil generated by the hammer. The remaining kinetic energy will continue to be transmitted to the balls and steel layers, causing them to bounce inside. This means that all the kinetic energy has been distributed and the hammer cannot bounce back anymore.
Thanks to this feature, the dead blow hammer can control the impact force with minimal rebound, reducing damage to the surface. This is especially important for delicate work on structures that require high precision, such as jewelry making or assembling electronic components.

Windings on transformer / inductor cores are the only things that i can think of. If i’m going to be honest, electrical engineering is an invalid point to bring up. It’s a white collar job that purely prioritises designing systems and a huge ally is physics and mathematics. In corporations some of the engineers design entire motherboards or multi voltage constant current power supplies with active PFC, synchronous rectifiers on the secondary purely from scratch with absolute zero suggestions from electronics they may ever take apart which is a black magic in itself. Some may fall outside the realms of white collar engineering. The electrician is more likely to work with a hammer and after a complex interplay of a bad narrator i can see where they went wrong.

Dead blow hammers are also good for machinists. The workpieces are typically hit with a hammer so that they're bottomed and falt in the vice or on the supports (parallels) in the vice. Typically it's a dead blow hammer, but at simplest it can even be just a piece of round brass bar dropped on the workpiece. While it doesn't have to be a dead blow hammer, it makes it easier, because sometimes the bounce somehow causes the workpiece to kinda jump back up by a small distance in the vice ruining the piece if you don't notice it.
So basically it's the opposite of what a blacksmith would use.
@TheOneAndOnlySame
9 күн бұрын
Yes but not for the reason you may think. Metals that are hit when they are at forge temperature do not rebound anyway. When you see a blacksmith make his hammer rebound on his anvil it only tells you that the anvil face is hardened steel, and the hammer head is hardened steel, and that is what is necessary for forging. If one of the element wasn't proprer (too soft) then there will be minimal rebound and thus telltale sign that the gear isn't of good quality /in good condition Blacksmiths don't use rebound, because forging does not rebound.
Actually it is to protect the person who uses the hammer

Wow, so now we got recoil free hammer before gta 6😂
It’s good for freeing seized components without denting the surface on things that need a little percussive maintenance
Back in the days, when I was working in a mechanical workshop, we only had these hammers at the manufacturing machines. Steel hammers just do damaging workpieces and are sucky in general. To put a nail into a plank, yes, but for metal work, mostly no. The damped hammers are just way better to handle
Been making jewelry for 10 years and never thought to use a dead blow hammer. You don't need that much force often
Mechanics use these alot; specifically the plastic wrapped ones
So it’s a force pair by the way. Not some magic force in the same direction downwards. The recoil is directed opposite the surface it strikes.
As a mechanic we only use these hammers on aluminum.. or when driving kingpins in and you don't want to mushroom them..
It hits softer than a regular hammer. Is because F = mA. And if you reduce the density of the hammer, by makeing it hollow. The mass will be less, and so the force
“Reducing damage” Yeah ignore the fact this is actually adding impact force to counteract and overcome bounce back force which means it does more impact than a regular hammer on top of typically more mass and weight
Bro survived milim's death training but so did ranga
Finally, a fun informative utube short.. I told you it could be done ✅️
That's not how hammers work. The recoil is ALL the energy put into what it hit, but some gets reflected back. Absorbing the rebounded energy doesn't change the force of impact. AT ALL.
Посадка подшипника молотком это, конечно, шедевр...))

a very useful tool to help reduce fatigue. that said, that bearing at the end was not even close to being straight
I've used a dead blow to put bearings into place on small engines like the video shows. Not metal head though, great way to wreck a bearing. Ideally you would press the bearing into place.
Its the damned vector, they put the vector’s recoil mitigation on a hammer

You do kinda want some recoil on hammers sometimes. It helps lift the hammer allowing less energy consumption on long jobs. Imagine forging without any recoil 😂
You can also make a makeshift dead blow by holding a block of wood in between the hammer and the surface. And tapping on the wood.
It's quite akin to what happens to a human body in the old car without deformation areas - human body takes most of impact instead of a car.

Why is recoil bounce bad? The force is still the same, it exist... Just because the hammer doesn't bounce has NO BEARING on the object being impacted
