I've discovered that my torque wrench only goes up to 160 ft lbs. I need another 50 ft lbs to lock up the rear drive shafts into the wheel bearing hub.
I have an angle gauge and was wondering if it is possible to convert the remaining 50 ft lbs into degrees for the angle gauge? |

In the Machinist Handbook, page 1406 there is a method to determine torque via "turn-of-nut" or angle method. However you would need to be able to measure the elongation of the shaft.
According to the book, even using a calibrated torque wrench, the accuracy is +/- 24% Turn-of-nut or angle method is better at +/- 15% , numbers are better with a computer controlled torque wrench as used by modern factories. By feel is +/- 35% according to the book. |
