So a johnson bar multiplies torque by magic? Note I said it wouldst amount to much with a crow foot, just use some caution not to go too far and break it. Changing the anger of the wrench shifts some of the force from radial to axial and so reduces accuracy of the torque wrench. (Don't know about you but a little explanation helps me understand and remember.)

Which explains a lot.
