Question: What number of ft./lbs. Indicated on my torque wrench will give me the Actual ft./lbs. of torque I want on my bolt when I use an Extension ? There's gotta be a formula.
Answer: There is, I=A/(1+E) . I = Number of ft./lbs. indicated on your torque wrench's scale. A = Number of ft./lbs. of torque you want on the bolt. E = Length of extension,center to center,in feet (example: 4 inches = .333 feet or 4/12 = .333 feet).



Ah, this seems to work, Thanks, I new it was simple, just couldn't remember and didn't want to go dig through my notes.

As mentioned earlier there is alot of misinformation on the net, and in my first google search before I posted this thread I found some interesting formulas which added in parameters not necessary for the calculation.

I am personally thankfull this discussion didn't get to way out to get pulled. Hope everyone learned some new stuff along the way. I know my brain received some excercise.
