| Putting a barrel on an AR using a standard barrel nut wrench on a tapco armorers tool. But I don't have a torque wrench. Its recommended that you go to 35 lbs, how do I judge that and how important is it. |

Quoted:
Stand on a scale as you torque the nut. Torque=force (amt your weight goes down on the scale) x distance Problem is, that force is modified by a lever rotating radially around a fixed point. You'll actually get more mechanical advantage at certain points in the swing as well as modifying your body position in ways that might give false readings on the scale (Like leaning back to gain leverage on the arm). |
