Drill a 1/4 inch hole. Fill with silica sand. I got the sand from Johh (Free).
At first we used a cake decorating tip, a plastic cup and a little funnel to start filling. Nuh-uh. Then I figured out that if I indented the ball and poured sand in the dent it acted as its own funnel. Then John came up with the brilliant idea to put his skill-saw under the little bench to vibrate the sand into the hole.
after 2.5 hours we went from 1.8 pounds of sand to an 8lb ball. It's only about 1/3 full. My goal is 15-20 lb ball for slamming.
After it's full we'll patch it with a really good tire patch kit (4.88) and fill with a little air through the fill valve.
