When dealing with lower torque applications a good quality dial type is my preference. Tightening banjo bolts, injectors, and flare nuts; in some situation it may be impossible to torque without 12-point crowfoot wrenches and flare nut sockets. Remember when using a crowfoot wrench with a torque wench the length of the torque wrench increases so torque setting must be calculated (especially when dealing with in*lb).<br><br>Check out this link for torque wrench info (I’m not affiliated with Snap-on other than spending too much money on their tools). ;D<br>

 

Alpine, my mistake. Somehow couldn't picture what ya had in mind. Now that I got it right, sounds like a dandy and simple method of calibration, so long as the weights are accurate.<br><br>That gets a &quot;two thumbs up&quot; from this corner, I'll probably build one of those.<br><br>

So the weight of the bar doesn't play because it's balanced. I do calibrate torque wrenches for as low as 2Nm .<br>AlpineRAM<br>[/quote]<br><br>AlpineRAM very ingénues, I now have a new project.

 

FWIW Even the most accurate &quot;torque wrench&quot; can produce varied results when tightening similar bolts due to other variables such as bolt condition. Is the bolt new, used, dry, rusty, oiled? Are the threads rolled? The ideal way to &quot;torque&quot; a bolt is to produce a certain amount of stretch in the bolt. There are airtools with built in transducers that actually measure bolt stretch and stop just prior to reaching max. stretch. There are also published charts for each bolt indicating how many flats to turn the nut after the fitting is tight.<br><br>Course, what do I know, I still use the &quot;arm strong&quot; method.<br><br>Gene

I've found one problem with that method.

I've stripped way too many nuts.
Broke way too many bolts.
Stripped way too many screws.
Don't know my own strength sometimes .
Or, I'm putting a bit too much of my &quot;weight into it&quot; :

I definately need a torque wrench.
