Spare, but works
Note to users: the units are irrelevant so long as you’re consistent. The units don’t have to be all metric or all English. e.g. : if you use furlongs for both lengths and kg-inches for both torques, you get the right answer. It’s also important to know how to use a torque wrench with an extender: - Always keep the wrench and extension in line. (Not at an angle) - Always push from the center of the torque wrench’s handle (or wherever you measured L1 & L2 from) If you do those, it works great!
