Rotating batting plate

Spring is in the air & baseball season is upon us! My son needed an aid to help him load & rotate his back foot for baseball! I designed this to be used indoor or outdoor it has spikes designed to go into grass or softer dirt a baseball diamond will probably to compact & hard. Assembly: You will need 6mm air soft bbs - insert them into the turning top while its flat on a table.Once your have done this place the base over top of the rotating top.then flip it over while carefully holding the top tight to the base to keep the bbs in place,once flipped over make sure everything turns back and forth smoothly its is kind of noisy you could use a touch of grease on the bbs but i didn't. not needed in my eyes.once happy with the top is turning push in retaining pin in the center. (this will push pretty hard its made to go in and not come out)then your all set!!
