What does a Hand Baseball Sewer do?
Sews leather covers on baseballs and softballs: Places glue-dipped ball in buck frame and stretches both leather covers over ball. Pulls perforated edges of covers together with pliers and tacks covers into place with brads or staples. Sews covers onto ball with harness needle, using waxed linen thread.
