nice test, though the answer was obvious to me, by doing screenprinting by hand, I started to have that classic inflamation on my elbows, not like a lot, I realized early enough, so what I did was attaching two thick metal plates to the ratchet-..?..donnou in english... for adding weight, so I wouldn´t have to push so hard, what a difference, I always do it so now. The test is as I expected, if instead of a paralel movement, is a spinning powered movement...yyyyup´h, and yes I think the fact that weight is very stiff as much closed to the source of spin, much more effective, if one is to make a cheaper casting of the socket, that can be the "short" way, in the case of your grandpa´s. When it comes about this powered spinning machines, the fact of the alignment makes a huge difference, on this tests of internet with drillers and stuff, often they say tha the user does not realy matter...hmmhh, in real daily life work, I see terrible things done to machines screws fasteners and users themselves, just by not trying it as straight as possible, relying most of the work to the strength of the motor. It is essential concentrating all the strengh and different forces involved as much possible aligned. Well similar to martial arts, categories by weight... good to see this concept of motion improved in such a way interesting channel, youtube is infinte ;)

[@Lucas12v]

@@blockbertus i always assumed they flex (twist) within their elastic range which limits the power. Then they spring back between impacts. Thicker ones are stiffer and transmit more torque. they wont work with a ratchet or breaker bar because they never get a chance to spring back so they'll eventually exceed their torque spec and then get damaged. You also need to use a gun with a certain power range for them to be accurate. The ones i have seem to do a decent job but i still don't trust them for some reason. I use them for stuff that isn't too critical though.

[@dafirnz]

@@blockbertus Think of them as a 'best guess'. To get them any kind of accurate you need to calibrate the stick to the gun, to the air system.

I thought the same. But I think the power sockets are meant for gaining power in a specific job that comes up often (and didn't exist when the shop was setup). So these are sold as individual sockets and if a set of them is needed then its worth it to upgrade the wrench.

[@drister007]

Yeahh true, BUT you can make that weighted power socket yourself out of normal socket and a little bit of metal for maybe $5. Then it is MORE THAN worth it. :) So based od the results DIY weighted power socked DOES make sense.

[@TorqueTestChannel]

Lisle doesn't make a weighted socket that would fit this rig (anymore). We need 15/16" or 24mm, if we made the drive size and therefore thread size any smaller we would be stretching threads with these impacts, which means data becomes useless. This is because we're tightening the bolt more and more with the test, not loosening something stuck like you likely are. If you have a 15/16" or 24mm weighted socket, or want to make one and send it to use let us know!

There is something imho to the spring rate that ir refers to as anyone whose run an impact for a living (30+ years as a heavy duty mechanic) will tell you. If you wrap your hand around the socket on a stubborn fastener soaking up the vibration you will increase the breakaway torque and get carpal tunnel.

If you only need one or two sizes…. I can see it for a shop that has multiple mechanics, multiple impact wrenches, but keeps 1-4 common sizes of the power socket to be used by any tech as needed.

[@scottedwards3403]

Def makes a difference to the fastener lol

[@oldscratch3535]

I would imagine it does as the tool itself can move from the impacts instead of the impacts transferring its energy into the fastener. That's lost energy. Also, you can make some semi-auto handguns malfunction by limp wristing them. The entire gun moves backwards which robs the energy transfer needed to cycle the slide.

[@land_yoter]

I would say it definitely affects torque. It's likely just like letting a wheel spin while torquing on lugnuts, just from the other side. That energy that goes into your wrist is not going into the fastener.

[@michaelovitch]

It's all about rebound harmonic looks like,different impact speeds can be heard during tests,like different hardness on material The "flywheel" socket mass and inertia is tuned for lower frequencies obtainable with air impact. It reduces rebound,and is less efficient higher in frequencies. The thin wall chromed deep socket is harder material and has more mass ,but very close to the axis of rotation,so a small inertia,wich reduces parasitic rebound. You should try to eliminate the play in the square with shims,you would reduce or eliminate rebound,and find out different results.

First off, love the channel and the work you guys are doing. Secondly, the term 'beans' should be standardized in the industry lol. Imma start using it in my garage. Last, yall show the masses of each socket but not the moment of inertia (MOI) which is what is really providing the extra torque. I know MOI is not a well understood topic, and that it is hard to calculate for every socket, but I just wanted to point that out. Two sockets can have the same mass and different MOIs, it all depends on how far away the mass is from the axis of rotation; like the IR socket having that mass ring located far away from the axis of rotation. I really like how you showed the IR patent. This shows you put a lot of work in to this video, like you do with all of them. Thanks and keep up the great work!

Yea weighted sockets are always used once on a flywheel bolt and then they are forever in the toolbox. Seen this playout so many times myself included.

[@YamWarden]

Spring losses makes sense, but I think the most important factor in minimizing spring losses would actually be the closeness of the fit between the drive and the socket and the torsional rigidity of the tooling. The tighter the fit, the less rebound between drive and driven - as a thought experiment, you could imagine the ideal would be welding the socket onto the drive, resulting in near zero rebound between the drive and the socket (given that the welds don’t fail). I’d be interested to see an analysis of how drive fitment effects torque efficiency. As an addendum, I was racking my brain to figure out why the IR tooling would have such exceptional results when your comment about the flywheel principal not being very applicable due to the fact that the constant is angular acceleration and not angular velocity is spot on imop, and I think it might be thanks to the added rigidity rather than the added mass. The spring in spring losses is the tooling itself, and the wasted energy is stored with the socket acting as a torsion spring. More (or harder) material on the diameter of the tooling would resist twisting much better compared to conventional sockets and lead to a reduction in torsion spring losses.

[@BKD70]

I would never have guessed this outcome... I was thinking that the lighter sockets would fare better, because the gun has to accelerate the mass of the socket before it can transfer the energy into the fastener..... but now as I'm thinking about it, look at the "Newton's Cradle"... perhaps the weighted sockets prevent/absorb the rebound (reflected energy) so that the socket is more "in position" to transfer the next hammer blow... Thank you so much guys for this!!! Learn something new every day!!!!

[@wolvenscout6445]

I work at a tire shop, and I can vouch that those power sockets do work. I could have a stuck lug and sit there with the air impact for well over 15 seconds, and still get nothing. We used to only have one option in that case. Go grab a breaker bar, and potentially hurt yourself, which happened on occasion. But then we got a full set of those power sockets, which included 17mm, 19mm, 21mm, 7/8", and 15/16". They will break that stuck lug loose in under a second. The only downside to them which was briefly mentioned, is that you have to have the room to use them. For example, the 17mm rarely ever gets used, because most Mercedes/BMW wheels have the lug bolts recessed into the wheel, and the power socket is way too thick.

[@wrenchingfool5284]

I have first hand experience with the Lisle style sockets and can say they definitely work. I bought an old Civic with a broken timing belt, and used every tool that I had in my box or could borrow to try unsuccessfully to remove the 17mm crank pulley bolt. I even tried using a 3/4” air impact gun (unfortunately without having a 3/4” drive 17mm socket) and all it did was laugh at my reducer. I was highly dubious of these sockets, but bought a set as a final desperate attempt. The bolt came out within 5 seconds when using the super thicc walled socket. They definitely made me a believer. I’ve used the 17mm and 19mm now multiple times, as well as loaned them out a few times, and they always get the job done. I’ve even been able to use my weak Craftsman electric impact to remove the crank bolts when my IR air impact with a regular socket can’t.

I have "weighted" sockets which I use for removing honda and toyota crankshaft bolts. Makes all the difference in the world. Regular impact sockets many times won't remove the crankshaft bolt, but the heavier sockets work (f=ma).

[@jake9705]

Really fascinating result! In a linear system, the total kinetic energy increases linearly with mass if velocity is constant (KE=0.5mv²). Increasing velocity is more efficient however which is why we've seen a trend in reducing bullet weights in the military in favor of faster bullets. The equation does not exactly apply to your test since your test involves a rotating element but the principle is the same: with velocity constant, increasing mass should increase total kinetic energy (beans). Which it clearly did. But considering that the "super socket" costs $100, that implies a set of ten "super sockets" would cost... $1000!!! The cost for even ONE "super socket" makes you ask yourself: why not loosen all the lug nuts with a normal, $5 socket and a $25 cheater bar, then follow behind that with the normal socket on a normal impact gun to quickly remove all the lug nuts? I mean unless you're working in the pit stop of a Formula One race then the "super socket" seems like an overpriced luxury.

[@G5Hohn]

BPM is a critical variable because each of these tools and drive systems have some kind of natural frequency. They will spring back in some amount of time. If you can apply another blow before the spring back has fully returned, then the energy will "pile up" in the driven object. These heavy sockets work by lowering that torsional frequency, making the spring back take significantly more time. Time enough that another blow can be applied before it is fully returned. This time dynamic is also why some impacts simply don't work with torque sticks. Torque sticks also lower the torsional frequency, but they do it not by being heavier, they do it just by reduced stiffness. So a higher BPM impact will apply a blow before the torque stick has unwound from its deflection, thus allowing torque to pile up and far exceed the rating of the torque stick. It would be really great if torque stick makers would put a max BPM rating on their products so that people would use them properly. Finally, this dynamic is why the long extensions lose so much power. The long extensions are less stiff torsionally, and they tend to act a bit like torque sticks. If you repeated the long extension testing with a very high BPM tool and a very low BPM tool, you'd find the higher BPM tool can run a longer extension before the torque level falls off a lot.

I think the key is to match the mass on both sides of the impact, so that all the momentum is transferred. It has nothing to do with spring rate, just the math of where the energy ends up in a collision. So you want the bolt, socket, anvil, and hammer to each have the same mass and moment of inertia.

It pulled the bolt out like it was undoing a lug nut, it was almost magic. Needless to say that was one bet I was happy to lose.

This is on the book. I remember years ago I was reading Lincoln tech textbook it stated deep impact socket produces more torque than shallow. I tested it out on a Honda crank bolt, it’s true.

[@TheVexCortex]

I thought the power socket was a scam, good to know it actually does what it says. Do you think you could attach a dumbbell weight to a socket? Maybe machine the ID in a lathe for an interference fit with the socket, then press it on?

[@ShaunHensley]

Why not just weld a weight on it?

[@TheVexCortex]

@@ShaunHensley A lot of weights are cast iron, cast iron is hard to weld and you need special materials. Even if the weights are not cast iron, you would still have an issue trying to weld dissimilar metals. Even if you did manage to weld them together, the socket would be weakened from the heat, making it a potential explosion hazard.

[@z33tanner]

Big fan of weighted sockets for removing crank bolts! I have a 22m lisle and plan on picking up the 19mm too.

[@justinweaver7553]

Thick wall sockets are amazing, the Honda crank bolt I could not get loose even with a 3 foot breaker bat and the proper holding tool was spun off easy borrowing the thick socket. I bought my own after using it.

[@OhioPowerTool]

Great info! Always get this question on how much it actually works. Thank you!

[@TorqueTestChannel]

You bet! The answer is 20-34% across all tools we've tested (when you actually divide top power run vs bottom run to get increase).

[@nickoloes]

If you're going to take off a honda harmonic balancer/crank bolt with a 1/2 impact don't even bother trying without the lisle socket. Maybe it can be done with a standard 3/4" drive socket but I don't have one of those to verify. Good luck to trying hand tools as well; I broke 2 ratchets and a breaker bar before I got power tools and even then struggled until I found someone in the forums saying you need the lilse socket.

[@IndependenceIron]

Spring rates can be changed in many ways such as socket wall thickness, socket length, and even local stiffnesses within the socket such as around the anvil, or around where it interfaces with the nut will affect the total spring rate of the socket.. I do believe mass can also play a role. I would say to truely segregate spring rate of the sockets from pure mass would be to test a socket and then attach a mass such as a collar to the socket and retest. Will have to be careful and attach it to an area that already has significant stiffness like around the anvil connection. Also want to limit stiffness increases to the socket to an attachment method like epoxy such as JB Weld might be more suitable instead of pressing on a collar or welding on a collar.

[@JimmyMakingitwork]

Yes.

[@RobertLeBlancPhoto]

Does the weight need to be welded to the socket, or can you simply add a weight fitting between the gun and the socket, so you can just buy the weight and use your existing impact sockets?

[@joebegley3062]

Awesome info, honda crankshaft bolts are notoriously tight

[@RR-fi4oh]

This is superlatively useful info. Thanks!👍👍

[@arthor1212]

I was really surprised by the stubby socket losing out. It makes sense with it being the lightest but I'll usually grab that if the longer socket is too wobbly like you showed, and the stubby would usually do the trick, interesting

[@deflepperdrocks12954]

Interesting video but now I want to see you sleeve a normal socket with some pipe and see what kind of results you get, jbweld or a similar compound would probably be the best way to attach it without potentially impairing the strength of the socket like welding could

[@wingerrrrrrrrr]

I'd like to see high speed photomicrography video of the IR socket in action, showing the outer ring moving like a torsion spring in relation to the central core. That's why the cutouts rather than filling it all in.

[@stinkycheese804]

@@wingerrrrrrrrr No, the cutouts are there to provide the best distortion reduction to weight increase, ratio. Torsion spring action is exactly what you want to avoid because it reduces impact force in order to store energy and gradually dissipate, just as it does in any other application.

[@James3076081]

I have gotten extra torque out of my impact by turning the socket by hand while it's hammering. I assume it's because I'm effectively damping the springyness of the socket. Would be very interested to see you involve this in one of your tests as a cheap alternative to that power socket.

[@kramsey253]

I used to do the same thing it seemed to make a difference.

[@porthole2]

I'm not surprised the 1970's chrome craftsman didn't break. That was a different era for American made quality tools. My first 'set' of tools purchased in 1973 or 74. was a Craftsman tool box full of 1/4, 3/8 and 1/2 inch chrome mostly 12 point sockets, deep and shallow. I still have most of them and put a lot of abuse to them with a 25+ year career in the automotive - truck filed (new car dealers). I only broke a couple.

[@Joe_Blo]

I have a set of those deep 6 point protective sockets and they work well for around $6 each. More than worth buying even if you have other sockets that fit, because they don't beat up the lug nuts or scratch the wheel. BUT! You have to be careful which brand you purchase. Some are cast knockoffs and will shatter according to some reviews.

[@badassbanana100]

I noticed alot of loss in the recoil or violent rattling while bolting up and impacting structural bolts (and disassembly) so to mitigate that i put my hand on the socket and turn it along as i impact. Effectively cutting out the space that the socket is used as an anvil to torque bolt. It seems to work wonders tightening and loostening for me in the feild and gives corded impacts that extra umph needed in a pinch and air the extra umph needed when you really need it 🤣 wouldnt recomend it all the time if you dont want arthritis when your old. But works for me. either way loved the video and just thought id share my experience as to why that flywheel socket thing makes sense as to why it would work in mt head

[@KF1]

A weighted adapter would seem to make more sense than weighting each individual socket. Would also give options depending on adapter length for keeping the extra diameter further back from the fastener, potentially allowing more room than the hoola-hoop socket.

[@peters1821]

I do have the IR 19 mm special socket and it does work. I broke loose probably at least 4 Honda crank bolt with it.

[@mightyfinejonboy]

how would the results change using an extension or as someone mentioned what about a very heavy diy modified extension having an effect? great video btw and learned a lot!!

[@kenbtheman]

Didn't really need to watch this video to know the answer. I've used weighted sockets for years now. I made my first one about 15 years ago. Pulled the pulley flange of an old water pump. Bored it out and welded it to the center of a 3/4 do impact socket. Worked like a charm. Made a few more after that. Now all the to manufacturers make them.

[@guywithjeep]

Love my weighted balancer socket, works every time.

[@johnmorgan4017]

Very cool. The size of the socket is the biggest issue. The over sized weighted would be more sensible outside of lugnuts. It’s still all subjective. I have a 7yo silver eagle that will out do a new milwaukee. Depending on the application. It’s a speed vs length of throw issue.

[@tellrowland2370]

Don't need to watch to know they 100% do work but I'm still gonna because your videos are awesome 👍

[@beechfox3423]

Doing the lords work. You guys are awesome.

[@600ccgsxr8]

THANK YOU THANK YOU THANK YOU THANK YOU THANK YOU. I asked for this a week or two ago, that's fast service!

[@thomebau895]

Way better idea: A short weighted flywheel extension. You only need buy it once and keep using your existing sockets...

[@georgeg708]

Guys I don’t know anything about what I just watched and yet I watched the whole video which says something about the channel 😂

[@charlespaluha1247]

I've owned some of these Ingersoll Rand sockets for years and tested them in real applications using air and everything else they are badass they remove things that nothing else can

[@wallywest2360]

I'm a bit fuzzy on the physics behind this. A flywheel works by resisting changes in rotational speed. It soaks up engine power as you're accelerating, and then releases it when you aren't. But that shifting of energy from one side of the equation to the other requires a fair amount of rpms to have any real effect. As you can see on the dyno the impact wrench doesn't really spin the socket much at all, so the flywheel effect would be basically nothing. And if you're working on a really stuck bolt it's not rotating at all. So the only other consideration is increased mass. If you think of an impact wrench like using a hammer on a standard wrench to bust loose a stubborn bolt, and when the normal hammer doesn't work you get your mini-sledge out and it does, then you can see the benefit of increased mass. But we're not increasing the mass of the "hammer" in this case, as that's all happening inside the impact wrench. We're effectively adding mass to the thing we're hitting with the hammer, which seems like it wouldn't do too much. IR's claim is that this is reducing a spring effect inherent to the impact wrench design. Going back to the hammer + wrench analogy if you pre-load the wrench by twisting it in the direction you want it to go before hitting it with the hammer you'll have better luck. And if you get a nice solid hit that doesn't bounce off that tends to work better too. So I *think* that's what's happening here. A heavier, stronger socket will tend to absorb the blows without chattering/bouncing as much, which results in more torque being actually delivered where you want it. Another example would be trying to hammer a nail into a piece of wood trim. If the wood is hanging off the edge of your table it's not going to happen, every time you hit the nail the wood flexes and the nail doesn't go through. But lay it on a solid base and the nail goes right in. This could also explain the difference in rated torque output of these tools and the actual measurements seen on this channel. The ratings are just mathematical projections based on the internal design of the tool, but do not take into account any losses from a less than perfect connection between the tool and the thing you're using it on. The less flex, or springiness, you get from the socket the closer to the theoretical max torque the tool can produce. Presumably then some ridiculously massive, 20 pound socket, would get reasonably close to the rated torque output.

[@fredygump5578]

Do the impact driver specific drives like the Milwaukee "Shockwave" ones increase torque? Or do they break less? Break more? Or are they just going for style points?

[@ameunier41]

Project farm did a video on this and they break more. If I remember right they didn't made more torque.

[@longbob9545]

defiantly would of loved to see the super thick honda crank bolt socket
