Another possibility is a device like this one that I've found are reasonably accurate and can be used to check your torque wrench(s). You clamp one end in a vise and put your torque wrench in the other for a good sanity check. I have a different brand, but this one from H-F is very similar and not very expensive: https://www.harborfreight.com/12-in-...ter-63917.html. Also can be used to convert a regular wrench into a torque wrench.
Thank you, Paul! That's great to know and now i won't be trying to rig up that manual torque calibrator anymore - glad to cross that off of my list of to dos! I'll go ahead and buy that torque adapter you mentioned - thanks for the good suggestions, as always!
