Torque wrench question.

[KUNZ,BOB (HP-Boise,ex1)]

I think everyone agrees that extensions on the handle end don't effect what
the torque wrench does on the drive end. The only issue here is that your
extension has to behave like your hand would have on the handle end. In
general, you'll have two contact points with your extension and that adds a
second order complication to the math.

But... what the original question was about was putting the extension on the
drive side (like the 2079 tool does). In that case, there is a
multiplicative effect. See my other post that runs through the math.
