Lesson 1Intermediate checks during each step: measuring weight, balance, straightness, and visual inspection pointsHere yuh wi establish a routine of intermediate checks at each stage. Yuh wi measure weight, balance, straightness, an stiffness, record values, an use visual inspection points fi catch problems early before dem become irreversible.
