Abstract
A rotatable member is adapted for dynamic balancing by the addition of balancing weights in the form of high speed projectiles fired at the member during rotation in timed relationship with the rotation of the member so as to impact the member at specific circumaxial locations required for balancing the member. The member has an annular groove for receiving the projectiles and securing the same at the desired locations. The groove has a cross sectional configuration slightly smaller than that of the projectile in at least one direction of measurement so as to engage and capture the projectile in retention in the groove.
