Crap, see I'm doing it all wrong. I have the same setup but haven't been charging my riding buddies a damn thing to change their tires. I'm like you and try to use a torque wrench any time I'm working in the shop. A good friend who is a very good mechanic laughs at me and says the last time he used a torque wrench was to pass his test in school. He does use a torque wrench for heads etc.
