    FC, I'm a fitter and turner, worked most of my adult life as a diesel fitter or mechanic, I try not to tell people how to suck eggs because most already "know", you seem to want help so this pic is from Norbar, they know a thing or two about torque wrenchs, if your extension is 90° to the wrench use the same setting as what is called for, if it's inline as in the pic use this formula.

    Thanks 408, It actually came with instructions to add 6inch/lbs to the desired setting to allow for the extra length.

    I would have thought that you would have to set it lighter if you were using an extension of some description.

    That is also what 408 reckons Beags!.

    Buchanans, the spoke people who make the tool say add the 6inch/lbs though.
    Find it hard to believe they have put the wrong directions on the tool for so long and not been told of the error.
    Fuckety fuck fuck, now I am doubting things.
    If the workshop manual says torque spokes to 55inch/lbs do I set the wrench to 61 or 49?

    I would be experimenting with it beforehand.  
    You could clamp a nut in the vice and screw in a bolt. Set the torque wrench to 55 inch/lbs and tension it just with the wrench. Then put the extension on and tension it and see if it moves.
    You could then do the same thing in reverse, using the extension first and then the standard wrench. 
    You've went to the trouble of buying the torque wrench so I reckon you probably want to get it right.
    Let us know how you go.

    Could you take a pic of how the extension attaches to the wrench FC ?
    I was thinking of it as a direct extension but it probably isn't.  If it connects to the square drive that would mean you now have two lever points  in the equation and that would complicate matters.
    As you said before,  if the manufacturer has been in the business for a while you would think that they would know what they are doing.

    Don't know how I missed that FC !
    Probably cos I'm using the phone. 
    I can't see Hilly's post properly on the phone either, did you manage to apply the equation he supplied?
    Make sure you tell us how you go with it.
