Method for checking torque wrench accuracy?
I bought a real nice snap on 1/2" drive torque wrench (30-150lbs), and am thinking of getting a 3/8" (5-75lbs) one as well. I've been told that recalibration runs about $50 ea., but that with careful, casual use, that that won't be neccessary for 4-5 yrs by snap on. You all seem very creative, and I was wondering if anyone has a way of testing a torque wrench for accuracy, or a general idea of how accurate. I hesitate picking up the second one because it seems a little extreme to spend $100 every year or two to calibrate a wrench that sees not a lot of use. What do you guys think?
Thanks, David |

For most of us torque wrench recalibration is as useful as bathroom scale recalibration.
I can't imagine these go significatly out of calibration for what your doing. But if you want to do it, make a simple 1 ft bar to hang weights from; something like. . .  . . .the idea being; 60lbs pulling at a right angle (90°) to the 1ft bar will pop the wrench set at 60 ft-lbs. A 2ft bar at 30lbs will also get you 60 ft-lbs. . . .Get it? ------------------ '81 Platinum Metalic SC Coupe [This message has been edited by island911 (edited 06-13-2001).] |
