Bobbielinks, can you send a pic of your carts/shelves? I heard at a long arm guild meeting about using the rolling base of an old office chair that you take the chair off of and slip a PVC pipe over the left-over post, then slip the bat roll over the PVC pipe. That way you can move it and it doesn't take as much space, but I can't figure out how to get the hydraulic assemble off the chair post! Duh! I don't like putting bat on the bat bar under the frame, have to stand on my head to get it.
