A got a hold of a torque wrench ... at flea market some years ago, I think. I brought it to some auto parts stores, and the clerks had never seen one like this. One guy said, "My grandpa had one of those.." ( Yeah, I feel old... ) Anyway, it reads in pound per inch, not pounds per foot as manual specs follow. So to use it, take the manual specs in feet, multiply by twelve ( 12 inches = 1 foot ), and use that number with this particular wrench. Example: the torque specifications in Haynes Manual for a 20 R "Thermostatic Valve Bolt" is 15 lbs per foot. So in using this torque wrench, multiply 15x12 = 180. Is this correct? I understand that the numbers on this gauge wheel are so large that accuracy might not be the best method. So what are your perspectives?
