ABSTRACT:
A method for forming a shaft with protrusions applies vertical pressure to the shaft to deformably displace material from the shaft to form one or more protrusions. The protrusions retaangularly spaced on and circumferentially aligned relative to the peripheral surface of the shaft. The shaft may be of any diameter, but typically three-eighths inch with the protrusions forming a larger diameter of typically one-half inch.
