The only other breakdown diagram of a torque wrench I find is the
Harbor Freight 1/2" clicker. Hand drawn and not properly named parts.
The operations aren't as smooth as the Danaher, but the last time I
checked it was very close. Really not bad for a $14 on sale torque
wrench. Guess it's time to borrow a beam type.
