Great Job Sir. I'm highly intrigued to see this... I helped someone who was on the side of the road... so he already had the wheel off, which kinda made me think "Really?????" But, whatever, we threw the spare on, hammered it down, and I told him "Follow me to my house, we will recheck everything..." At the house, I was shocked to see the lug nuts were over spec.... when you hold them, and run them, they feel like they are made out of processed compressed scam nuggets.... but for no good reason, they seem to work....
Honestly for and older lady or man this is perfect, some people are fully capable of changing a wheel but lack the strength they once had. This is perfect for them
After this review, it gained a lot more credibility, atleast for me. It's the kind of tool that you don't use very often but you'll be glad you have. Would be a good idea to put one on the wife's car.
lol except for the garbage clickbait videos showing these piles of junk beating Milwaukee and dewalt impacts breaking away nuts but they have them set to forward lol more garbage clickbait junk!
I've got one similar but it's much bigger and quite heavy for its size and has the handle on the back like a small jackhammer. Quite powerful as it takes a 30A fuse inline with the battery clamps. It will loosen nuts and bolts that my air impact won't come close to moving,great for those 4x4 wheel nuts that the shop does up with a million pound impact every time i get new tyres.
Great video, once again. I'd love to see a mid-grade shop impact like this, ~$120 that takes an M18 battery with max torque rivaling big 3/4" impacts. I don't need the big guns very often, but would be glad to have something like that sitting on the shelf.
I’d imagine just like any centrifugal clutch that adding spring pressure will delay engagement to a higher rpm and doing so should see some gains! Especially if combined with a better motor or just over voltage
I have had one of those for over 10yrs. I hadn't used it in a while, and it froze up. I took it apart, and it works good as new. They are definitely a big help especially if you go to a shop that uses an impact and over torques the lug nuts.
Once again thanks for the awesome content! a modified version of this impact with a stronger motor, heavier "flywheel" that releases the "hammer blow" at higher rpm would be really interesting to see. I imagine we are starting to enter the wrist breaking territory, so a better handle is recommended :P
Fascinating! I bought this type of lugnut removal tool back in like 2005 and sung it's praises for many years as I was able to help multiple people with flat tires, including myself once. The Achilles heel, however, seemed to be the cold. I noticed it worked a lot less - or not at all - when it was very cold out, which unfortunately is fairly common in Minnesota. But it served me for more than a decade before it stopped working one day.
These impacts first appeared about 20 years ago - the Shentai. I bought one ($AU70) and it got me out of a huge problem in the outback. I blew a diff pinion seal and needed to replace it. The impact easily removed the pinion nut, and enabled me to replace it plus about + 1/64th turn. Worth it's weight in gold. It will also undo rusted exhaust flange nuts that need 2 long extension bars to reach, where the bars absorb all the torque of a normal wrench. This was before the days of the Li battery powered tools we now love.
One of my cars came with a similar impact wrench, though it's a bit more "gun shaped". The previous owner was a bit older so he used it to help with the winter tire changes :D Don't have the car anymore but I did keep the little gun. It came with a nice combination sized impact socket and damn if it doesn't work...
I bought a 12V impact beater gun from Harbor Freight about 20 years ago and yes it did remove that Honda crank bolt without breaking a sweat. I paid $27 back then and included 4 lugnut sockets. This thing works better than any air impact that I've owned Including an 18V impact gun from Bosch. Bosch is not the beast, the impact beater gun is for a fraction of the cost.
i have one of these "single use" 12v tools, but its an air compressor for tires. i've actually used it quite a few times over the years, and i've careful not to let it overheat. if you let these things run wild though, they will hit pretty hard and then melt into slag lol
The more decent quality ones can go on a bit longer, but they still end up burning hot after a while. It's also a good idea to take them apart every now and again and grease the bearings and cylinder so that it has a fighting chance (rubber safe grease of course)
That does seem pretty uniquely suited to emergency and junkyard duty if you don't have big cordless tools. Seems pretty creative. I was initially guessing it was tightening some kind of spring until it couldn't anymore.
Bought the Harbor Freight version of this back in 2006 and its still going. Ive used it a couple hundred times, paired with alligator leads, going to a 18v lithium battery. The oem plug used a low amp fuse, which I replaced. This was the only issue I had.
I wonder if you gave the motor more power (18v? 24v?) if it would hammer any harder or will the blows be the same? I'd love to see a video of a suped-up version of this thing (more power to the motor, stronger springs so the mass reaches higher speed before engaging with the shaft) I could see this thing competing with the mid range impact drivers.
It should hammer roughly just as hard since the impact happens at a certain speed, though higher voltage and current will make it reach that speed (and burn out the motor) sooner. Since its already stupid strong but also stupid slow, that'd definitely be a "hell yeah!". Combined with stronger springs for a harder hit, I bet this thing would be an absolute monster until it shatters into a hundred pieces or catches on fire. Worth noting that he's (sort of) undervolting it already. Plug in car tools are generally meant to be used while the engine is running, so it should be a bit faster with the 14-15v that the alternator puts out.
I don't think 18 volts would really be a problem or a benefit, but 24 would put more than needed stress on the windings, it wouldn't hit any harder though as the entire hard hitting action is based on springs and you might gain at max a whole half second between hits
But faster RPM the spring will engage sooner soon may not get as much omph. What if you change the spring tension so that it could spin up even higher RPM before engaging therefore having more momentum hitting on the anvil.
That hammer design is pretty ingenious in its simplicity. I'd love to tinker with something like that. Increasing the anvil weight, increasing spring tension, using a better motor. Also interesting to note, you can see that sometimes the lever rocks backwards and catches on the hammer as it is knocked back, that raises a couple of questions for me if the mechanism could be adjusted to make that controllable that might give some great loosening ability to the mechanism, first off the motor wont have to fight against the reverse inertia in the assembly to spin it back up, secondly, that reversed impact hit could provide a slight wiggling action to the nut/bolt as its going to be wiggled slightly back n forth every hit. Only thing I'm not sure of is how much energy going into the hit in the intended direction, if we're talking like 9:1 that would be acceptable but obviously anything that gets closer to 5:5 is just going to be net neutral.
I saw a video a little while ago featuring that gem. That is interesting seeing what makes it tic. The new camera gear was worth it for sure. Great job
Motor torque is superfluous in this case, you could make it hit a bit faster with a higher RPM motor but given the percentage of time that the reset action takes it would be a minimal improvement. Now if you machined a channel for the tilting mechanism, machined the mechanism to right tolerances, and did very precise calibration on the springs you could probably get significant improvement in blows per minute, but at the cost of massive increase in cost.
@@andrewfidel2220 A more powerful motor would be faster to bring the hammer up to full speed, initiating another hammer blow. If the rate of impacting could be increased from 1 Hz to say 3 Hz without changing the force per blow, it would result in a quite impressive tool.
Awesome you guys put this out, I saw one of these on another channel and I was debating getting one for my dad. Glad to know for the investment, it's good for emergencies. I wouldn't trust my life on it, like it's not a daily driver but for replacing a tire once in a blue moon, sounds like it could be handy.
This is the first time I've seen the egg beater (I'm a welder/fabricator, if something needs beans I open the oxy/acet tanks in my back yard) - I'm really impressed
I picked one of these sets up a few years ago and use it twice a year to switch between summer and winter tires. I live in a apartment and this box is all I need to do it in a parking lot. I am using a torque wrench to tighten though.
I had an older more pistol type of one of these I kept in the trunk as a tool of last resort, slow, but it hit surprisingly hard until it let the smoke out. Took out more than one bolt where jumping on the breaker bar didn't.
What a clever little contraption! You'd obviously never use this in a shop unless you were tragically desperate, but it's nonetheless ideally suited to its intended task and market. Nobody wants to spend a ton of money on a beefy impact wrench just to leave it in the car for years in case you get a flat, but you also need something with enough oomph to loosen a stuck bolt. The downsides (cheap construction, slow overall action, awkward form factor) are simply not relevant for its intended roadside emergency use, and the multi-rotation momentum building trick lets them pack a lot of punch without placing unreasonable demands on the power supply. Smart engineering at its finest!
This was really neat! I might need to chuck one in the trunk of my car, now that I'm getting old and decrepid... not that my car has a place for a spare tire anyway...
I saw one with what looked like a V8 and a hand lever that made it interfere after you spun up the engine. I dunno about high quality but it seems to slap
@@TorqueTestChannel I'd imagine that one with even more mass, and/or perhaps somehow adjustable max RPM before the hammer tilts would be able to overcome any fastener.
I’ve actually mod mine when I was in college I had no money to buy a 18v branded impact but still want to work on my car/bikes So I got a old car starter motor swap out the original motor in the tool use it with a adjustable power supply set to 14v and it works great It only takes one hit to crack loose a normal car wheel nuts (tq to 120nm)
Thanks for covering the egg beater. I have the same scissor jack but I modded it to take my impact wrench. Zips the car up or down fast. Good for working on cars if u need to support weight quickly for engine or trans. It's not very strong, not for hd trucks. I think their motorized jack is ok 🤔 impact is much faster 😆 yea I think the egg beater will remain a curiosity. It is capable and surprisingly so. But I think I'd get a lot more mileage from a regular cordless impact.
Cool! I figured it had to be some sort of centrifugal clutch to account for its sound & behavior. Not sure if I want one of these per car, or if I should just loosen & retorque the lug nuts every so often to make sure they can be removed with the usual wrench should the need arise.
My senior citizen father had one of those, it actually saved his bacon more than once. I recommend them to older folks that can still physically lift the tire.
Loved the video! TylerTube kinda tested this thing, and now it’s been truly tested! Keep finding more oddball tools to test, maybe we’ll find a odd gem like this again. 👍
I have one that the principle is the same, but milder like a traditional impact driver. One thing to consider is those will perform even better by a wide margin if the car is running. With 14+ volts the speed of the hammering is quite faster vs on a regular 12 volts not being charged.
Yeah, wasn't a fair test if only 12V was being provided (might even be less under load). Should be 14V. Having said that, it's likely not very reliable and I'd expect it to break when needed most. Might be the motor that dies, might be some gear teeth...
"centripetal force pushes the heavier side out" Nitpick: centripetal means center seeking. Centripetal force pushes things in, not out. The word you're looking for is the one people love to claim isn't real because their 9th grade science teacher said so, centrifugal.
That always rubbed me the wrong way. Maybe there's no such thing as "centrifugal force," but it's a word that accurately describes angular momentum. It's like saying an ant isn't a bug, it's an insect. Bug is just the word people use
Right? Can't we all just agree that when there is a centrifugal (center fleeing) acceleration, it's fine to be a bit lazy and attribute that to centrifugal force? At the very least, stop attributing outward acceleration to centripetal force, because that's simply wrong.
The centripetal force is actually at the pivot, preventing the rocker from flying to infinity from the axis of rotation. The pin also has a tangential component that is making it he rocker go around.
It would be neat to see one of these things modified via gear reduction to a hand crank. A hand powered impact wrench. For you know, replacing carriage wheels after the EMP event hits and there's no more electricity.
I've got a 50 year old Milwaukee generator that will withstand an EMP attack. It's like a cockroach with a 5hp Briggs and Scrapiron flathead. I've also got an old corded impact. I'll be all set for buggy wheel changes, even in the dark.
The high current draw that blew the fuse is an issue on many import 12v “car” tools. Lots of cars only have 10A on those cigarette lighters some have 15A. I have a HF “compresssor” with this issue, I put a current clamp on and measured 12A under load though it has a 15A fuse in the plug. Going straight to the battery is the solution as long as you add an appropriate fuse. That little pump is a beast.
I mostly have owned pre-1990s cars, presently a 1979 Subaru DL wagon, a 1967 Chrysler Newport, and a 1978 Chevy C10. Due to the port being an actual cigarette lighter port, they often have super high amp fuses and thick wiring from the factory. I've seen 20 or 25 in GM cars fairly often, 20 or 30 in Chryslers, and I've seen anywhere between 15 and 40 in Japanese cars. My Subaru as an example, the cigarette lighter port is ceramic on the inside, and has 10 gauge wiring and a 30 amp fuse. On the other hand I've seen as low as a 5 amp fuse on newer cars. My mom's Jetta has only 5 amps for the front 12v socket. And of course fuse box diagrams are not even available since they seem to have changed it at least 5 times during that generation of Jetta.
I bought a 12 compressor to carry in my work vehicle and it works just fine using the accessory outlet, but there is a big difference in performance with the vehicle shut off compared to the vehicle running. Try it if possible plugged into a 12 volt source with the vehicle running and see if it has more power.
I'm a mechanic in maine and most lug nuts I encounter you'd have to be the hulk to remove with the little lug wrench you get would definitely be good to have in the trunk for many
When i first saw this, i assumed it was gonna function like any other impact but cheaper, but the way this works seems like a slower, but highly effective method of getting things done, and it makes me think of what it would be like if it was fitted with a heavier weight and a better motor so it could be priced similarly to a decent conventional impact. I have a feeling it would become great at removing rusted and very tight nuts. It would probably also become a bolt snapper 5000, but that's besides the point lol
I always assumed these were complete junk. Now you actually have me interested in one. Damn you TTC for making such fantastic content. Also, would be super interested in you guys testing tire inflators like the digital one that Astro makes. I've always used the Astro one, but recently it got broken and I'm back in the market. Matco's $170 price point just doesn't seem worth it, and can't help but wondering if there are better options out there.
Ill stick with my 4 way and my small floor jack. (one of those little 2.5 tons floor jacks that has the 2 foot handle or so) It is however nice to see that this stuff does actually work.. mostly as intended.
I put the rod with the hook on those crappy jacks in my drill and it goes up and down fast. The last one I used actually had a nut the same size as the lugs so I was able to use the impact and just give it the beans!
That's definetly cool! I bet your wrists felt wonderful after testing it all day, so your pain is appreciated. Now... could you by chance upgrade the snot out it please?
What limits this is the motor overheating. Higher power input means higher power output means shorter duration. So I guess the amount of work it can do until it needs to cool down would be about equal.
@@TorqueTestChannel ¿Pero? ¿El cable de alimentación,es de al menos 2 mm?pues saben traer de 0,75 x 2 , entonces hay que medir el voltaje en pleno trabajo y en contra del motor,si llega 11 v hay mucho para mejorar
I use a DCD996 in low gear with a custom drive fitting to do most of my jacking with oem scissor jacks. Other than the safety issues if used stupidly I find I wear them out periodically resulting in a seize up occurring during full beans use. It's not the threads that go, it's the low speed thrust bearings getting too hot at speed. :-)

At the house, I was shocked to see the lug nuts were over spec....
when you hold them, and run them, they feel like they are made out of processed compressed scam nuggets.... but for no good reason, they seem to work....
Honestly for and older lady or man this is perfect, some people are fully capable of changing a wheel but lack the strength they once had. This is perfect for them
After this review, it gained a lot more credibility, atleast for me.
It's the kind of tool that you don't use very often but you'll be glad you have.
Would be a good idea to put one on the wife's car.
Singlecams has great channel! Been watching for quite awhile. Nice to see this impact on the dyno, it's comical but spicy
lol except for the garbage clickbait videos showing these piles of junk beating Milwaukee and dewalt impacts breaking away nuts but they have them set to forward lol more garbage clickbait junk!
@@tylerbaldwin1633 Um no but thanks anyway
I've got one similar but it's much bigger and quite heavy for its size and has the handle on the back like a small jackhammer. Quite powerful as it takes a 30A fuse inline with the battery clamps. It will loosen nuts and bolts that my air impact won't come close to moving,great for those 4x4 wheel nuts that the shop does up with a million pound impact every time i get new tyres.
What’s the name of that one?!? I gotta get one lol
Great video, once again. I'd love to see a mid-grade shop impact like this, ~$120 that takes an M18 battery with max torque rivaling big 3/4" impacts. I don't need the big guns very often, but would be glad to have something like that sitting on the shelf.
I’d imagine just like any centrifugal clutch that adding spring pressure will delay engagement to a higher rpm and doing so should see some gains! Especially if combined with a better motor or just over voltage
If you do this this thing might suffer a RUD
I have had one of those for over 10yrs. I hadn't used it in a while, and it froze up. I took it apart, and it works good as new. They are definitely a big help especially if you go to a shop that uses an impact and over torques the lug nuts.
Once again thanks for the awesome content! a modified version of this impact with a stronger motor, heavier "flywheel" that releases the "hammer blow" at higher rpm would be really interesting to see.
I imagine we are starting to enter the wrist breaking territory, so a better handle is recommended :P
The hard-hitting science that I come to this channel for!
Fascinating! I bought this type of lugnut removal tool back in like 2005 and sung it's praises for many years as I was able to help multiple people with flat tires, including myself once.
The Achilles heel, however, seemed to be the cold.
I noticed it worked a lot less - or not at all - when it was very cold out, which unfortunately is fairly common in Minnesota.
But it served me for more than a decade before it stopped working one day.
These impacts first appeared about 20 years ago - the Shentai. I bought one ($AU70) and it got me out of a huge problem in the outback. I blew a diff pinion seal and needed to replace it. The impact easily removed the pinion nut, and enabled me to replace it plus about + 1/64th turn. Worth it's weight in gold. It will also undo rusted exhaust flange nuts that need 2 long extension bars to reach, where the bars absorb all the torque of a normal wrench. This was before the days of the Li battery powered tools we now love.
One of my cars came with a similar impact wrench, though it's a bit more "gun shaped". The previous owner was a bit older so he used it to help with the winter tire changes :D
Don't have the car anymore but I did keep the little gun. It came with a nice combination sized impact socket and damn if it doesn't work...
I bought a 12V impact beater gun from Harbor Freight about 20 years ago and yes it did remove that Honda crank bolt without breaking a sweat. I paid $27 back then and included 4 lugnut sockets. This thing works better than any air impact that I've owned Including an 18V impact gun from Bosch. Bosch is not the beast, the impact beater gun is for a fraction of the cost.
i have one of these "single use" 12v tools, but its an air compressor for tires. i've actually used it quite a few times over the years, and i've careful not to let it overheat. if you let these things run wild though, they will hit pretty hard and then melt into slag lol
Yup. I had to wait 5min for my old one to cool FOR HALF EACH TIRE. Thats 8 use/cooldown cycles for one car.
The more decent quality ones can go on a bit longer, but they still end up burning hot after a while. It's also a good idea to take them apart every now and again and grease the bearings and cylinder so that it has a fighting chance (rubber safe grease of course)
That does seem pretty uniquely suited to emergency and junkyard duty if you don't have big cordless tools. Seems pretty creative. I was initially guessing it was tightening some kind of spring until it couldn't anymore.
Love that you grabbed one of these..I'll hang on to my m18 mid torque for now lol..thank TTC
"Because using all this sensitive equipment on a funky 100 dollar Amazon toolkit sounds amazing, really."
This, but unironically
Bought the Harbor Freight version of this back in 2006 and its still going. Ive used it a couple hundred times, paired with alligator leads, going to a 18v lithium battery.
The oem plug used a low amp fuse, which I replaced. This was the only issue I had.
I wonder if you gave the motor more power (18v? 24v?) if it would hammer any harder or will the blows be the same? I'd love to see a video of a suped-up version of this thing (more power to the motor, stronger springs so the mass reaches higher speed before engaging with the shaft) I could see this thing competing with the mid range impact drivers.
It should hammer roughly just as hard since the impact happens at a certain speed, though higher voltage and current will make it reach that speed (and burn out the motor) sooner. Since its already stupid strong but also stupid slow, that'd definitely be a "hell yeah!". Combined with stronger springs for a harder hit, I bet this thing would be an absolute monster until it shatters into a hundred pieces or catches on fire.
Worth noting that he's (sort of) undervolting it already. Plug in car tools are generally meant to be used while the engine is running, so it should be a bit faster with the 14-15v that the alternator puts out.
I don't think 18 volts would really be a problem or a benefit, but 24 would put more than needed stress on the windings, it wouldn't hit any harder though as the entire hard hitting action is based on springs and you might gain at max a whole half second between hits
Use a dc rc motor, high rpms
Mod this thing up!
But faster RPM the spring will engage sooner soon may not get as much omph. What if you change the spring tension so that it could spin up even higher RPM before engaging therefore having more momentum hitting on the anvil.
That hammer design is pretty ingenious in its simplicity. I'd love to tinker with something like that.
Increasing the anvil weight, increasing spring tension, using a better motor.
Also interesting to note, you can see that sometimes the lever rocks backwards and catches on the hammer as it is knocked back, that raises a couple of questions for me if the mechanism could be adjusted to make that controllable that might give some great loosening ability to the mechanism, first off the motor wont have to fight against the reverse inertia in the assembly to spin it back up, secondly, that reversed impact hit could provide a slight wiggling action to the nut/bolt as its going to be wiggled slightly back n forth every hit.
Only thing I'm not sure of is how much energy going into the hit in the intended direction, if we're talking like 9:1 that would be acceptable but obviously anything that gets closer to 5:5 is just going to be net neutral.
I love this channel. The oddball stuff is always exciting to see
That’s actually really cool, super cheap for emergency purposes or just an overall cheap option but it still has its place
i have been waiting a long time for this one :D
I saw a video a little while ago featuring that gem.
That is interesting seeing what makes it tic. The new camera gear was worth it for sure. Great job
Am I the only one who wants to see how effective this hammer assembly could be with a much more powerful motor behind it?
Motor torque is superfluous in this case, you could make it hit a bit faster with a higher RPM motor but given the percentage of time that the reset action takes it would be a minimal improvement. Now if you machined a channel for the tilting mechanism, machined the mechanism to right tolerances, and did very precise calibration on the springs you could probably get significant improvement in blows per minute, but at the cost of massive increase in cost.
@@andrewfidel2220 A more powerful motor would be faster to bring the hammer up to full speed, initiating another hammer blow. If the rate of impacting could be increased from 1 Hz to say 3 Hz without changing the force per blow, it would result in a quite impressive tool.
Awesome you guys put this out, I saw one of these on another channel and I was debating getting one for my dad. Glad to know for the investment, it's good for emergencies. I wouldn't trust my life on it, like it's not a daily driver but for replacing a tire once in a blue moon, sounds like it could be handy.
This is the first time I've seen the egg beater (I'm a welder/fabricator, if something needs beans I open the oxy/acet tanks in my back yard) - I'm really impressed
I picked one of these sets up a few years ago and use it twice a year to switch between summer and winter tires. I live in a apartment and this box is all I need to do it in a parking lot. I am using a torque wrench to tighten though.
I have had one similar for years and I love it have not had one lug nut that it has not been able to undo.
Thanks for testing this kind of tool at last. Long ago I challenged a UA-camr to send his into TTC in the comments, but he declined.
I had an older more pistol type of one of these I kept in the trunk as a tool of last resort, slow, but it hit surprisingly hard until it let the smoke out. Took out more than one bolt where jumping on the breaker bar didn't.
We absolutely appreciate you my brother! 👌
dude the egg beater is impressive lmaooooooooooooooooooo
What a clever little contraption! You'd obviously never use this in a shop unless you were tragically desperate, but it's nonetheless ideally suited to its intended task and market. Nobody wants to spend a ton of money on a beefy impact wrench just to leave it in the car for years in case you get a flat, but you also need something with enough oomph to loosen a stuck bolt. The downsides (cheap construction, slow overall action, awkward form factor) are simply not relevant for its intended roadside emergency use, and the multi-rotation momentum building trick lets them pack a lot of punch without placing unreasonable demands on the power supply. Smart engineering at its finest!
This was really neat! I might need to chuck one in the trunk of my car, now that I'm getting old and decrepid... not that my car has a place for a spare tire anyway...
I used a similar 12 volt floor jack as a outboard motor lift on my old 40 Mercury. Heck of a lot easier than manual lifting it. Nice work guys.
Wow that is interesting. I wonder if there are higher quality or name brand versions of these style impacts.
I saw one with what looked like a V8 and a hand lever that made it interfere after you spun up the engine. I dunno about high quality but it seems to slap
@@TorqueTestChannel I'd imagine that one with even more mass, and/or perhaps somehow adjustable max RPM before the hammer tilts would be able to overcome any fastener.
Thanks for doing my suggestion from last video! These little impacts are strange!
Seeing yall test the swench would awesome
I’ve actually mod mine when I was in college
I had no money to buy a 18v branded impact but still want to work on my car/bikes
So I got a old car starter motor swap out the original motor in the tool use it with a adjustable power supply set to 14v and it works great
It only takes one hit to crack loose a normal car wheel nuts (tq to 120nm)
glad singlecams got a shoutout. great channel
Finally an impact driver for the kitchen, my souffles will never be the same again
The Egg beater icon on the graph and "uggas..... Then duggahs" too funny 😂😂
You should replace the springs with slightly heavier ones to get it to spin up to a higher RPM. More powa!!
This was cool! It would be awesome to see someone make a homemade egg beater impact that’s on a 20v or 24v battery that does double the rpm!
Thanks for covering the egg beater. I have the same scissor jack but I modded it to take my impact wrench. Zips the car up or down fast. Good for working on cars if u need to support weight quickly for engine or trans. It's not very strong, not for hd trucks. I think their motorized jack is ok 🤔 impact is much faster 😆 yea I think the egg beater will remain a curiosity. It is capable and surprisingly so. But I think I'd get a lot more mileage from a regular cordless impact.
The egg batter design makes a lot of sense for its intended purpose.
Cool! I figured it had to be some sort of centrifugal clutch to account for its sound & behavior. Not sure if I want one of these per car, or if I should just loosen & retorque the lug nuts every so often to make sure they can be removed with the usual wrench should the need arise.
My senior citizen father had one of those, it actually saved his bacon more than once. I recommend them to older folks that can still physically lift the tire.
I had a good laugh about not crawling under the car with that jack. Neat video
Loved the video! TylerTube kinda tested this thing, and now it’s been truly tested! Keep finding more oddball tools to test, maybe we’ll find a odd gem like this again. 👍
Okay this is some very clever engineering 🤯
I have one that the principle is the same, but milder like a traditional impact driver. One thing to consider is those will perform even better by a wide margin if the car is running. With 14+ volts the speed of the hammering is quite faster vs on a regular 12 volts not being charged.
Yeah, wasn't a fair test if only 12V was being provided (might even be less under load). Should be 14V. Having said that, it's likely not very reliable and I'd expect it to break when needed most. Might be the motor that dies, might be some gear teeth...
One day I decided to put one of these onto a 14.4v rc car lipo battery and I was amazed how well it did. Now it lives in my car
"centripetal force pushes the heavier side out"
Nitpick: centripetal means center seeking. Centripetal force pushes things in, not out. The word you're looking for is the one people love to claim isn't real because their 9th grade science teacher said so, centrifugal.
That always rubbed me the wrong way. Maybe there's no such thing as "centrifugal force," but it's a word that accurately describes angular momentum. It's like saying an ant isn't a bug, it's an insect. Bug is just the word people use
Right? Can't we all just agree that when there is a centrifugal (center fleeing) acceleration, it's fine to be a bit lazy and attribute that to centrifugal force? At the very least, stop attributing outward acceleration to centripetal force, because that's simply wrong.
The centripetal force is actually at the pivot, preventing the rocker from flying to infinity from the axis of rotation. The pin also has a tangential component that is making it he rocker go around.
You guys are doing gods work
Thanks for doing this. I was really fascinated with it and now I won’t make fun of it anymore.
Totally unexpected.
Nice work!
very interesting design, would be cool to see a premium brand make one of these to see the potential when real money is put into it
Great Vid I have been waiting to see this type of impact reviewed I just didn't know what it was called !
It would be neat to see one of these things modified via gear reduction to a hand crank. A hand powered impact wrench. For you know, replacing carriage wheels after the EMP event hits and there's no more electricity.
The reduction needed... Probably better off getting a cheaper and easier to use cheater bar.
@@jonanderson5137 No that just makes too much sense.
Garage 54 channel made a flywheel starter for a lada 😂 you could maybe bring the size down for just bolts 🤔
I've got a 50 year old Milwaukee generator that will withstand an EMP attack. It's like a cockroach with a 5hp Briggs and Scrapiron flathead. I've also got an old corded impact. I'll be all set for buggy wheel changes, even in the dark.
The high current draw that blew the fuse is an issue on many import 12v “car” tools. Lots of cars only have 10A on those cigarette lighters some have 15A. I have a HF “compresssor” with this issue, I put a current clamp on and measured 12A under load though it has a 15A fuse in the plug. Going straight to the battery is the solution as long as you add an appropriate fuse. That little pump is a beast.
I mostly have owned pre-1990s cars, presently a 1979 Subaru DL wagon, a 1967 Chrysler Newport, and a 1978 Chevy C10. Due to the port being an actual cigarette lighter port, they often have super high amp fuses and thick wiring from the factory. I've seen 20 or 25 in GM cars fairly often, 20 or 30 in Chryslers, and I've seen anywhere between 15 and 40 in Japanese cars. My Subaru as an example, the cigarette lighter port is ceramic on the inside, and has 10 gauge wiring and a 30 amp fuse. On the other hand I've seen as low as a 5 amp fuse on newer cars. My mom's Jetta has only 5 amps for the front 12v socket. And of course fuse box diagrams are not even available since they seem to have changed it at least 5 times during that generation of Jetta.
I bought a 12 compressor to carry in my work vehicle and it works just fine using the accessory outlet, but there is a big difference in performance with the vehicle shut off compared to the vehicle running. Try it if possible plugged into a 12 volt source with the vehicle running and see if it has more power.
The way this works reminds me of one of those big electric impact wrenches ("el-max" we call them) used for removing lug nuts on trucks.
I'm a mechanic in maine and most lug nuts I encounter you'd have to be the hulk to remove with the little lug wrench you get
would definitely be good to have in the trunk for many
Great video as always! Thanks.
When i first saw this, i assumed it was gonna function like any other impact but cheaper, but the way this works seems like a slower, but highly effective method of getting things done, and it makes me think of what it would be like if it was fitted with a heavier weight and a better motor so it could be priced similarly to a decent conventional impact. I have a feeling it would become great at removing rusted and very tight nuts. It would probably also become a bolt snapper 5000, but that's besides the point lol
I always assumed these were complete junk. Now you actually have me interested in one. Damn you TTC for making such fantastic content. Also, would be super interested in you guys testing tire inflators like the digital one that Astro makes. I've always used the Astro one, but recently it got broken and I'm back in the market. Matco's $170 price point just doesn't seem worth it, and can't help but wondering if there are better options out there.
Saw this video, had to make some coffee and sit down. It's time to see what this egg beater can do!
Simple and useful design. Imagine what that tech could be when applied by a better company.
Ill stick with my 4 way and my small floor jack. (one of those little 2.5 tons floor jacks that has the 2 foot handle or so) It is however nice to see that this stuff does actually work.. mostly as intended.
I completely forgot about that afront to the car gods 😅
I put the rod with the hook on those crappy jacks in my drill and it goes up and down fast. The last one I used actually had a nut the same size as the lugs so I was able to use the impact and just give it the beans!
That's definetly cool! I bet your wrists felt wonderful after testing it all day, so your pain is appreciated.
Now... could you by chance upgrade the snot out it please?
What if you hooked it to a diesel engine jumper pack on the booster setting (aka more voltage)? More spice?
Since it's for a car, if the engine is running it would be getting 14-15 volts and maybe an interesting test
What limits this is the motor overheating. Higher power input means higher power output means shorter duration.
So I guess the amount of work it can do until it needs to cool down would be about equal.
The real limitation is the low amps available on those car outlets. Not much juice there.
Half the footage is at 14.5V
@@TorqueTestChannel ¿Pero? ¿El cable de alimentación,es de al menos 2 mm?pues saben traer de 0,75 x 2 , entonces hay que medir el voltaje en pleno trabajo y en contra del motor,si llega 11 v hay mucho para mejorar
I bought one of those electric scissor jacks, and yeah it did the infamous sideways tilt after shearing off the teeth at the bottom of the Jack
imagine a sponsor wanted to be anonymous and paid someone to diss on beetro
I use a DCD996 in low gear with a custom drive fitting to do most of my jacking with oem scissor jacks. Other than the safety issues if used stupidly I find I wear them out periodically resulting in a seize up occurring during full beans use. It's not the threads that go, it's the low speed thrust bearings getting too hot at speed. :-)
This kit and a solid booster pack would make one unstoppable at the scrap yard. Geez. I'd be divorced with all the crap I'd be bringing home. 🤣
Idk how I missed this upload because I’ve been hoping you’d test this thing!
