Re: What's da Best TorQue wrench for 140 ft-lb lug nuts?
Organise youself a decent reasonably long handle type wrench (ie. one of those extendable type ones - or else just get a nice long 1/2" breaker bar and suitable socket - I'd guess you need something about 2.5 to 3 feet long) - then work out the maths to calculate what weight is needed on the handle to give you your 140 ft/lb (ie. 140 lbs at 1 foot of leverage, 70 lbs at 2 foot lever etc.).
You need to then organise a way of feeling that weight in your hands. This will give you a good way of making an educated guesstimate of the force needed to get the torque more or less in the ballpark.
I guess you could also simply actually apply that weight directly to the handle (ie. make up a convenient block or something that can be put on / hung off the handle).
Much cheaper than a torque wrench.
