EXACTLY my point , Sigma !
Now , if you're using a "dogbone" , then the torque reading WILL change .

The longer handle just reduces the amount of force you have to apply to reach a given torque setting. The longer handle gives you more leverage, allowing you to do the same amount of work with less effort.

I have to disagree with you on this thought. The formula for torque is T = F x L. T = Torque, F = Force, L = Length. The length is the distance from the center of the socket to the end or grip of the handle. Therefore solving for T and leaving everything the same but changing L will give you different answers.
Example 1. F = 15, L = 16
T = 15*16
T = 240
Example 2. F = 15, L = 8
T = 15*8
T = 120
Example 3. F = 15, L = 24
T = 15*24
T = 360
Yes, but that's not how a torque wrench works. The torque wrench stops torquing whenever the torque exerted at the head exceeds whatever is dialed in. Put a 10' extension on it if you want, it will still stop at the same torque spec, it'll just be really easy for you to exert that force.
I stand corrected. But if you extend the length from the pivot point, will it change the torque? That is what the manual refers to in recalulating.

If you were to apply the same amount of force to the long handle that you did to the short handle, and if there were no mechanism in the head of the wrench to regulate that torque, then yes, you would have more torque applied at the head. Just remember that that equasion is probably assuming a simple pivot point and lever, not a torque wrench with its regulating internals.

bingo. That's the answer right there folks! If it was a wrench extended, then applied torque would be greater as proportional to length of extension and also the direction of applied torque. CCW=+, CW=- torque. Keep in mind also that if your line of action is perpendicular to your pivot, then you apply zero torque, just force. That has nothing to do with this, but it's nice to flex our brain muscles on the internet to increase our net-egos from time to time!

Er... what exactly is a "dogbone"? A regular crescent (box)wrench?

Um, guys, if I'm reading the original post correctly, he wasn't talking about extending the length of the handle, but about adding a standard extension between the torque wrench and the socket.
In this case, yes, you will lose some small amount of the applied torque, because some of the torque will go into the twisting of the extension, because it will basically act like a torsion spring. The general rule of thumb I've always followed is keep the distance from the tq wrench to the fastener as short as possible, and when you must use an extension, raise your applied torque a little bit; usually I'll lean toward the higher end of the spec of whatever I'm tightening when that is the case.

LOL. I missed that too when I read it. Thanks for opening my eyes.

Meh...It was late, I was tired, and it's hard being perfect 100% of the time. I think 99.9% perfect is good enough for me!
