I think I remember that post (story).I agree itis a very good tool to have. Learn from my experience and make sure you triple check whether itis ft lbs or in lbs in the spec. Its too painful a story to tell again......
definitely buy one and do as ohiobellboy stated above.And once you buy one,,,, remember to unload the spring in it after you're done using it for that project. Don't store it set at 140# just so you don't have to adjust it next time you rotate your truck tires. When I say unload the spring, I mean to turn the torque back to it's lowest setting.
Picked up a set from there with all 3 sizes for ~$40. May not be the top of the line quality but for occasional use they serve the purposeYou can get torque wrenches for a reasonable cost at Harbor Freight so if you have a store close by check them out. The torque wrenches at HF are not top of the line but they are within +/- 3 in accuracy. Most Harley torque specs have a top and bottom range for example 90 to 120 inch lbs so the +/-3 isn't a big factor.
I do lots of work on my bike and don't use a torque wrench, I do use a torque wrench for some of the more critical engine components. If you are not using a torque wrench just remember that in most cases you are tightening a metal bolt/screw into plastic or aluminum which is easier to strip.
