How to torque without a torque wrench

Use a scale to find the right torque

[jsprowse]

This is ingenious. Now I just need a breaker bar and a fish scale. *Googles: "How to torque without a breaker bar or fish scale"

This method is more effective on lower torques. For higher torques, things start to slip out of place as you don't have a firm enough grip on the handle of the power bar/ratchet.

Good but important to ensure you are pulling at 90 degrees to the wrench, otherwise you could undertorque the bolt since you will be vectoring the force.

I figured a luggage scale would do the trick, but I didn't take into consideration the distance aspect. Very valuable information. Thank you.

Very interesting and helpful - thank you! Particularly the bit about the distance down the bar from the bolt being important.

this was exactly what I was looking for. great explanation

[migfed]

Beautiful video. About first principles and really useful for a lot of purposes and people. Thank you so much.

Such a handy method! Gonna try this soon on my tappet cover!

[diedonner]

Great video! Thanks for the easy explanation of this.

Brilliant video learnt alot in such short time. Great idea

[duvalpenny]

Awesome! Used this method for inch pounds. Was a little hard holding the tiny Allen wrench on while hanging 15 pounds on the end, but I got it to work!

Thanks. I came here hoping I could estimate 4.4 foot lbs, a bicycle stem install. No torque wrench

This is the more recommended approach for our average infrequent users. A proper torque wrench requires re-calibration every year. Just not worth the money and effort if not using it frequently

thank you this video saved me over 50$ on the tool

Unfortunately you are mistaken. You are adding fastening weight, on the weight of ratchet. Ratched itself, makes a torque value on the bolt, before you start adding weight. Means youre applying over torque. That method can only used horizontally.

I have a cheap torque wrench that starts at 5 I need 6 but I think is already too tight &it doesn’t click I’ll use this trick to make sure

Ryan - This is what Youtube is made for I only need to torque one bolt and definately not worth 330 for a wrench - Thanks for the information and the video - Chris UK

Hi great video and since then I use pretty much any tool that I have for a torque wrench. You have to divide the deemed force by the length of the tool in feet or meters depending on the scale you are using. So that would be kilograms-force required divided by length of the tools IN meters (e.g. 23 cm would be 0.23 meters) -> you get the kilograms that you need to weigh with the scales. That's for kilogram-force meter example. Same for pound-force foot - you divide the required force by the length of the tool IN feet.

One of My cousins who has been an Engineer(Lead Engineer now) at Raytheon for about 25 years saw this video and said this is funny. Yes i realize this is not aerospace parts here, but if helps to make planes as safe as they are…..
