. . . about the recent threads on torque values got me asking “How many of these guys have a calibrated torque wrench”. I have one – but “calibrated”. NOT lately? I am going to embark on a (near?) total restoration of my SIII in a matter of months.
Hmmm . . … . . got me thinking. I picked up a Snap-On 3/8" torque from eBay years (decades??) ago. It has sat in my toolbox un-used while I finished a stint in the Army and did Def Contracting work in AFG and then some more years.
So I found a test lab in the Springs and dropped off my wrench. Three days and $33.50 later: the Certificate of Calibration says “Calibrated to +/-4% of setting”. I was expecting 2%. So I asked the gal at the counter who said 4% was about as good as it gets. I assume she meant for a torque wrench clunking around in a tool box. I suspect the standards are higher in certain industries with wrenches much more expensive than my eBay purchase.
The cert references a couple Mil Stds and TOs but (and here is my question), also says “Calibrated to at least a 4:1 calibrated ratio.” What is that? I Googled the phrase but am still in the dark. Anyone simplify this for a guy with a Crim Just BS?
