As a follow up, are the cheap ass torque wrenches you can get at harbor freight worth using for the 10 times in my life I'll need one? Oftentimes, I think of harbor freight tools' shortcomings being that they don't last, but if I'm only going to be using it 10 times, that's not a huge deal. For a beam torque wrench that doesn't get calibrated anyway, are those close enough to be using? I don't tend to use for my crankarms and everything I own is steel or aluminum, but that pretty Thomson stem I just bought has specs printed on it, so I don't know whether I should be more precise than my usual "torque it down until it doesn't move when I put some leverage on the part and then tighten it half a turn or so more" approach.
