[QUOTE="Huggy, post: 2004883, member: 101145"] As one who used torture wrenches on a daily basis while employed in the aviation industry for decades, I wholeheartedly agree with using a torque wrench for repeatability. That said I want to mention that the typical torque wrench you buy from Sears, Auto Zone or wherever are said to COME setup with a certification of accuracy but wrenches SHOULD be tested on a regular basis. When I was still employed our employer paid to have all of our torque wrenches certified every six months (I had six different kinds of torque wrench gear) and it can be expensive. Point is, even if you store your wrench in a suitable container for travel, they can and WILL lose accuracy and sometimes for no reason at all. But should you drop your wrench it is HIGHLY recommended you refrain from using it again until it has been tested for accuracy. I have seen homemade devices to do a home calibration that seem to be accurate and verifiable, but you need to know how to adjust your wrench to bring it back into specifications, not something familiar to the average DIY'er. Lastly, and to make a point, I have a quality SnapOn torque wrench I happened to not use at all between calibrations and when it went in it was found to be out of spec. Why that happens is anybody's guess. So don't buy a torque wrench and think it is a buy and fly for free forever. You might find out you're under or OVER torquing a widget. At best the widget is a little loose. At worse you stretch the threads and ruin a barrel or (heaven Forbid) your receiver. Buyer beware and educate yourself WRT owning and using a torque wrench. Good Luck in your endeavors, Sir. [/QUOTE]
