Well, i also just realized that I don't ahve a torque wrench that goes down to 20 in/lbs, lowest I have is 25 in/lbs. So, how critical is it that I use a torque wrench for the base. I obviously don't want to overtorque, but I don't want to undertorque it either, and what about the rings? Critical to torque to exact specs? Sorry about the dumb questions. Thanks.
