After coaches lay each row, they mix one bag of ready-mix concrete and fill the concrete blocks openings even with their tops. Between the sixth and seventh rows and the ninth and tenth rows, coaches place four eight inch long one-half inch diameter electrical conduit pipe eight inches in from both sides of the rebound wall. Rebound Boards Coaches need to attach boards to their rebound walls to absorb the force of the thrown iron balls. Next, coaches align the rebound board's bottom edge with the fifth row's top edge and clamp the rebound board to the rebound wall. Then, coaches gently push the threaded rods through the drilled holes.
Coaches tighten the nuts flush with the threaded rod front side ends.
Coaches place the rebound wall return ramp against the rebound board. The table of contents for this eBook provide an easy to use navigation tool for Dr. Marshall's superb text.
