      Good tip! You could also extend the handle with a pipe, or make your own tool to hang those weights at specific distances every time you do this. Ie. a two foot pipe with notches for the string at 12 and 18 inches, choose your weights according to the specs on the wrench. Super simple calibration every time. You also don´t need so much weight if you extend the leverage, so that might be a thing too.

    Most cheap high street wrenches are way off and need calibrating.
    I Used to calibrate equipment as a tech support engineer both eletrical from fluke meters to torque wrenches Ultra light 6ft lbs too 500ft lb long bar.
    Good advice for a rough home setting.
    I'll just add to get it spot on you ideally need to check the lowest, the mid & the highest settings as the spring tension accuracy can vary hugely and may show that the tool is no longer accurate on all settings.
    Most common reason is because people dont reset the wrench back to its lowest setting after use and just leave it for months with the internal spring under constant load.

      These clicker type wrenches are typically calibrated for the force applied exactly at the middle of the grip (and it does matter, there are a few videos explaining and clearly demonstrating this), therefore that should be the point you hang your weights from and measure the distance to. Ideally, one should test different hanging positions on the handle with different weights at both ends of the wrench's torque range, find the position that gives the most accurate results throughout the torque range and then only apply force at that exact position during normal use. Whether it's going to be the middle of the handle or closer to either end of it really depends on each specific wrench model.

    Minimum spec on my Torque Wrench was 20 FT Pounds. I didn't do much math and still calibrated it. I though to myself "Foot, pound" Therefor 1 Foot away from the head should required 20pounds of load is what is needed to click it at the 20Foot Pound setting. So i filled up a bucket with 20 pounds worth of water and i was able to perfectly calibrate it. *I was able to verify this theorie with a new one and it clicked right when i was laying down the handle of the bucket on it.

    This is the best DIY demo I've found. The process is not that complicated, although for accuracy the right angle distance and mass need to be accurate. I've often wondered how much ambient temperature affects this clicker style of wrench. In the end, most of the time a variance of 5% is fine. Often it is a comparative tool, so even if it is out a little, all the bolts will have the same torque. These days we tend to go overboard with torque, although the margin for error in aluminum housings can be small.

    • @VintageEngineRepairs
      @VintageEngineRepairs  Před 11 měsíci +6

      Thanks for watching :) I agree, for what we all do 5% even 10% is not a problem. Heck you could be even further out and not have any issues. If it was on a a spaceship then it’s a different ball game. This gets you very close, easy to do at home and will be far more accurate than doing it by hand :) thanks for watching!

    • @IM_I1985
      @IM_I1985 Před 9 měsíci +1

      I agree that this is a clever way for diy calibration. Although not complete. Even though the style of torque wrench you show here is common, there are a lot of different ones. And the method of adjustment also differs. Some do have the screw you show now, but also a lock screw for instance. A lot of professional wrenches also feature an adjustable scale.
      Typically you adjust the screw you show in the video to set max torque, and adjust the scale for minium torque. Most cheaper wrenches have a fixed scale and I would recommend calibrating for the range you use, as it will be hard to get it right all along the scale.
      Most professional torque wrenches are supposed to be within a 3% margin along the full scale. Typical calibration is done at 0% 60% and 100% force. It will be hard to get it to within this spec with this diy solution. But it's definitely better than not checking it at all. The 3% margin is also ludicrous if you ask me, how you hold the wrench, how you apply force, is your bolt dry or lubed, etc will have more effect on the end result the a bit bigger margin on your wrench.
      Bear in mind that the electronic force gauges might also not be accurate. Especially cheap models can have quite some deviation. So you might want to check the force gauge with this method before using it to calibrate.
      In short, good method for approximate calibration with little expense. But not suitable for critical work.
      Just my 2 cents as someone in the tool business, including calibrations.

    • @dubmob151
      @dubmob151 Před 9 měsíci

      The wrench handle should be horizontal; maybe it's the camera angle that makes it look like it's pointed down, which would make it require a higher torque to click off.

    Great video. I'm going to try this out myself. One note: I think it is important for the torque wrench handle to be parallel to the ground. If it isn't parallel (or as nearly so as possible) then the effective length is different from the measured length thanks to vector trigonometry.

      Yes sir you’re spot on! I think it’s important to be as accurate as we can, but also remember that even if things aren’t precision perfect - it will still be more than good enough for what we do :) you won’t snap bolts being a bit over nor will it cause an engine to fail being a bit under the specified torque.

      ​@@VintageEngineRepairs Just as a follow up, if you're within 10˚ of horizontal you'll be within 2% of accuracy, which is equivalent to +/- 4mm on your length measurement. Given your string is about 4mm in diameter, that's plenty of precision.
      If you get out to 20˚ you're still within 7% of the calculated value, but it starts to rapidly fall off in accuracy after that.

  • @spelunkerd
    @spelunkerd Před 11 měsíci +23

    One thing not accounted for with this method is the weight of the handle, which is small but not zero. In the big picture it's likely negligible. I suppose one could measure this with a simple experiment. Suspend the wrench with a string looped around the center of the head, then support the handle end with a scale. Multiply the measured scale weight by the right angle distance from scale contact point to string, and you've got baseline torque with no extra weight added.

    • @VintageEngineRepairs
      @VintageEngineRepairs  Před 11 měsíci +5

      Yeah I agree with you, it’s negligible, as mentioned before, for what we do, it’s not going to make a difference. Most torque wrenches come with, from memory, +/- 10% accuracy. Thanks for watching and commenting, it’s always good to hear other people’s opinions and ideas :)

    when you turn the setting handle, you're shortening the length of the torque wrench - you need to compensate for that when positioning your string because the initial measure is now off - should reposition the string at the original measurement of 11" which would require confirming with your measure tape (would shift slightly towards the end of the wrench a bit). small detail.

    When I was taught to use a torque wrench many year ago. We were told that the break in the knurling or the thin band of knurling was where your middle finger was supposed to be placed. The reason given was that this represented the calibrated distance from the drive head to achieve the most accurate torque.

      @@stargazer7644 It does matter where you hold and calibrate the torque wrench. You are meant to apply the force at the groove that all of these torque wrenches have. They all have them for a reason. I know that may be unexpected because a torque is a torque after all, but these click-style torque wrenches complicate things somewhat.
      There are actually two torques in play here: one torque at the head of the torque wrench which is wrenching on some fastener, which is what we want to measure, and another torque at the "elbow" between the head and the handle. The torque wrench actually measure the torque at the elbow, which is where the clicker is, and we use that to stand in for the torque at the head. That works fine if we calibrate things right to give us the right numbers.
      However, the calibration assumes a particular ratio between the handle length and head length.
      To gain an intuition for this, imagine a particular torque wrench that has a particular torque dialed in. In your imagination, apply a torque at the groove and make the wrench click. Now, leaving everything else exactly the same, modify the wrench to lengthen the head and shorten the handle, but let's leave the total length the same as before. Let's say the handle is now half as long as it was, which means that the elbow will now be approximately half way along the wrench. Now, apply the same torque as before. Will it click? No, it won't because the lever arm to the elbow is half as long as it was before. You will have to apply twice the force to make it click now.
      That shows that the ratio between the two lengths does matter. Going back to the original torque wrench now, if you apply the force at a different place, you will be changing the ratio.

    • @dgphi
      @dgphi Před 25 dny

      ​@@stargazer7644 The force from your hand should be applied at the same point that the calibration force was applied. You might as well use the groove that is put there for that purpose in every single click-style torque wrench.
      I know what you are saying. A torque is a torque. But that doesn't apply to click-style torque wrenches, as I explained above, because the "elbow" point, where the clicker is, is not at the same place as the "socket" point.
      The actual measurement point (the "elbow") is not exactly at the same place as the intended torque application point (the "socket").
      For other styles of torque wrench such as a digital one or a deflecting beam one, then yes, it wouldn't matter where you hold it because the measurement point (the transducer in the digital one for instance) is at exactly the same place as the socket.

  • @TornadoCAN99
    @TornadoCAN99 Před 10 měsíci +4

    I prefer using a small luggage or fish scale, cheap to buy and accurate enough for this. Then just keep it at the measured distance on the wrench handle while pulling handle at 90 degree until it clicks...read max "weight" on the display. Adjust wrench calibration accordingly. This keeps the force at 90 degree to handle, no contribution from handle's own weight (as in this example with handle adding small amount to turning downward force applied). And no need for any calculations nor pre-weighed dead weights.

    Great video and so simple to do. I have been told by multiple tool shops that the smooth ring in the handle is the factory point where they test the torque wrench. Not sure if it is true but you might as well use it as a fixed point for future calibrations so you get the same point each time. You'll also notice that the ring is slightly closer the end of the grip, this is because when we pull on a handle at 90 degrees more of the force is concentrated towards the last 3 fingers (middle, ring and pinky) on our hand. This enables us to grip something very tightly while still being able to use our thumb and fore finger for other things. Try it out.

      Yes, I noticed on your last click test by hand you probably without thinking positioned your hand right over where that band is on the handle. Cheers, great video

      Yes, typically the handle is marked for this purpose. Not just for factory calibration, but also for recalibration. Different brands use different marks, but I would expect the clear ring to be the mark in this case.

    Great video for the home DIYer. It is also important to remember that these torque wrenches are more applicable when you're working with multiple bolts that all need to be torqued the same. I.e. car wheel lugs, or a pump head flange, etc. For a single bolt, especially in a sensitive application, these torque wrenches only bring you within a ballpark spec and probably not the best tool to use. But this calibration method is simple, quick and yields acceptable results, so thanks very much for sharing.

    • @VintageEngineRepairs
      @VintageEngineRepairs  Před 9 měsíci

      Thanks for watching and sharing, it’s a great method to set and keep your torque wrenches accurate for what we use them for. It’s not perfect with the small variables, but it’s more than accurate enough and offers anyone the ability to maintain theirs without any money spent.

  • @mrgoodman6620
    @mrgoodman6620 Před 11 měsíci +96

    After you set the torque, you've moved the spot you measured to, so dont you have to re measure from the socket drive because the spot on the handle you choose is now half inch or so up the bar??????

      If I were doing this, I’d just choose one of those grooves in your handle and then always use that. Find a way to measure the “proof weight” and the length as accurately as you can. Still, at the end of the day, the mechanism is only so accurate. You may get it perfectly calibrated, but then repeat the same torque application ten times and still get 1-2% difference in applied torque. Also, it’ll probably be different along the range of torques. It’d be interesting to get a digital torque gauge and then measure a bunch of settings to see how the variation looked along the range. Also, if you use the setup like in the video, you’d need to account for the weight of the torque wrench in addition to the proof mass. 😜

    @pepapu7112 Před měsícem +14

    I see 2 major flaws in your method, 1st: when you twist the handle to adjust the torque setting, the spot you've chosen to hang the weight has moved, now closer to the drive than you've measured before. To mitigate this, choose a torque and adjust wrench beforehand then calculate and measure where to hang the weights along the handle. 2nd: when it clicks, the torque wrench isn't perfectly parallel to the ground, it has sagged, hence the force of the weights acting on it isn't perfectly perpendicular. To mitigate this, let the wrench rest higher so when you put on the weights, it will click at approximately parallel to the ground.

  • @TheLonesometoad
    @TheLonesometoad Před 8 měsíci +3

    Why not hang the weight on it and then turn the screw until it clicks. Then you know you're dead nuts the first time.

      You put a lot of tension on the spring loading and twisting, but I do like that idea! Just not sure it’s going to be quicker.

    Well done Tom, I'd recommend everyone test their wrench at minimum, mid and maximum range. Let's face it, most of us won't have a bunch of torque wrenches where each has a range that overlaps the others in their kit by 50%, I know I can't afford that many. Whatever torque I need to apply, it will always only fit inside the range of one of my wrenches, that might be near the extremes of range. Excellent video, cheers.
