<div dir="ltr">DIY, the adjustment is simple and the process is not too complicated. There should be a plastic cap on the handle end of your torque wrench. Pull this off any you will find the adjust nut. Tighten to increase the amount of torque applied before the click, loosen to decrease. Now to calibrate, all you need is a known weight on a lever of known length. I use a 3' piece of heavy angle iron with a slot cut in it that is 1/2 wide. Next put a weight on the other end. 10 pounds at 3 feet and your torque wrench should click at 30ft-lbs. 20 pounds at 3' and your wrench should click at 60 ft-lbs. Just make sure the bar is horizontal, you need the force of gravity to be pulling straight down. The best practice is to calibrate at the high end of the range your wrench is capable of. This is not a lab method and the results will be off a little based on the weight of the bar and altitude at your location, etc, etc. But it is close enough for just about anything you are ever going to use it for.<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Thu, Aug 16, 2018 at 4:12 PM, Andrew Uprichard <span dir="ltr"><<a href="mailto:auprichard@uprichard.net" target="_blank">auprichard@uprichard.net</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div link="blue" vlink="purple" lang="EN-US"><div class="m_-3532130127784335801WordSection1"><p class="MsoNormal"><span style="font-family:"Times New Roman","serif"">Some time ago I bought 2 Craftsman torque wrenches at my local Sears.
