Full maths - measure the length of the spanner and use a spring balance on the end of the spanner. www.convertunits.com/from/1+N-m/to/Kg-mBut you would need a spring balance - and you already have a torque wrench (I know )

Forget all that maths bollox…..set the torque wrench to setting, tighten, then tighten some more….. Until the bolt snaps…… ….

Forget all that maths bollox…..set the torque wrench to setting, tighten, then tighten some more….. Until the bolt snaps…… …. I really only get drawn to using a torque wrench on two counts. 1. It is such a low torque - I am scared of over torquing it and shearing the fixing. 2. It is such a high torque - I too am scared of over torquing it and shearing the fixing. Like every tyre fitter in the land - nothing I have ever touched is knowingly under torqued!There are differing levels of "tight" - going from on the scale of "FT > MT > snapped" ------------ Had to ring what I thought to be an "awkward customer" only this week - bottom crankshaft bolt was "MT" - informed him of the risk. He said and I quote "if you break it - its down to you" - my reply was "we will abort, put it back together and charge you the labour up to this point". Can't be my fault his crankshaft bolt was murdertight - can it? I have never seen the car before!

my reply was "we will abort, put it back together and charge you the labour up to this point" Good call. I have had one or two of these "awkward customers" in the past - they only come to me because I'm cheap & careful. They also know that I'll spend days on end making special fixtures and tools to get around this sort of problem, then not charge them for the time.
Best give them good-riddance.
Don't get bitter (like me).......

I think I'm the only one in the workshop that reports 'this wont come undone, I need more (chargeable) time and it may need further time and parts to resolve' - pretty much everyone else blunders ahead regardless, it costs them time and the workshop parts unless the customer can be coerced into paying, which they mostly can't once it's at the 'broken' stage....

Who am I to "break" a customers car without the "customers authority".

It's the blame culture gradually infesting us from America unfortunately...

I think it is an "educational thing" - people in the UK can't or won't grasp facts when they are presented clearly in front of them. I get the escalating cost issue - but when challanged they just don't grasp the "problem".

At least in the USA, they have a "can-do" attitude to most things in life, even if they live in a litigation-society.
Life is about to become a bit more cruel for the molycoddled Brits that have been brought-up on consumerism and disposibility - they will have to "make do and mend" like generations earlier, if they want the luxuries in life.

Only yesterday - had a three year old BMW in workshop - broken locking wheel nut key (over torqued wheel bolts). Referal from tyre bay. Chap insisted I removed/replace the rear two as he needed two tyres. I asked what about the front two? He refused. I then said - what happens if you get a puncture on the front axle? He still refused based on the labour I would have charged for the extra two. This chap is school teacher - I think he is actually a head of year! Sadly he is in charge of "teaching" one of my grandchildren - nice enough chap - but can you see my point?

Interestingly,
My eldest girl came to visit for 2 new tyres for her Corsa… She forgot the lwn key!….
Unperturbed by this, our local garage, proceeded to fit the tyres….but destroyed one of the wheel nuts and smashed his removal key in the process….I felt bad for him….but thems the breaks I guess…

Go carefully. This is my modus-oparandi at the moment, but one of these can find any play in rear suspension or poor rear tyres, or (in my case on the Disco2) poor design out of the factory for rear-overhang and chassis instability and sway. The particular area of difficulty is in braking, especially downhill, when you are about to enter a corner, as the rear axle is very lightly loaded at that stage. If you have a vehicle with dodgy castor-angles on the frame, this can also increase the chances of a bad jackknife, even at low towing speeds.
Other than that, these are great, and the finish on yours looks fantastic, so it should last for a good few years. Mine is just a paint-finish, and there's no question that it relies on pure gauge of steel-thickness to keep its strength......
