ABSTRACT:
A weighted training bat formed of wood and having a handle and a barrel. The barrel has an elongated hollow cavity formed into a distal end thereof and an outer cavity portion having internal threads. Lead which has been poured or cast-in-place into and filling the proximal portion of the cavity, when solidified, adheres to the interior surface of the cavity to resist loosening, the lead adding weight at and evenly astride the sweet spot of the bat. An elongated wooden screw having external threads is tightly engaged into internal threads in the cavity so the screw bears against the lead to further prevent loosening of the lead. The threads are permanently glued and an outer end of the screw is formed to blend with the contour of the end of the barrel.
