I'm setting up my first ring and pinion and I have to set the pinion rotating torque to 10-15 in-lbs. My smallest torque wrench only goes down to 30 in-lbs and I can't find one that goes lower! Also, I assume the torque wrench would be 1/4" drive. Do I just use a couple adapters to get from 1/4" drive wrench to 1/2" drive socket or am I needing a specialty tool?
