We are happy to provide you with the following diagram of the hot-wire cart.  Click on the diagram to see a larger version that is suitable for printing.  The diagram prints best in MS Internet Explorer.  The drawing was made using "Solid Works" drafting software.  If you need more detailed drawings or better descriptions than is provided here, you may contact Dr. Chuck Gaston at 1031 Edgecomb Avenue, York, PA  17403, who can provide you with additional information (possibly even the drawing file itself).






Notes:  The insulated wires that carry current to the hot wire are fastened to the vertical posts on the cart using large binder clips. It is important that the wires are insulated for obvious reasons, not to mention the fact that the vertical posts are made from metal conduit.  The hot wire is then fastened between two alligator clips on the ends of the insulated wires and is suspended between the two vertical posts.  (You may want to refer to the photos on this website to help you get a better understanding of this arrangement, although wooden dowels were used in the original hot wire support.)  The wheels are lawn mower wheels and most of the rest of the cart is constructed from wood, except for the hardware and the diagonal metal struts made from adjustable shelving strips.  The base of the cart is constructed such that stackable, plastic milk crates (commonly available) can nest in the base.  That way the cart can double as a 2-wheel hand truck to cart around your Tarzan Swing equipment when not in use.  For added convenience, the cart can be constructed to fold nearly flat so that it can slip under the seats of a minivan.  To do this, the bottom piece of wood that the vertical posts are fastened to is not permanently fastened to the base of the cart.  Then this piece and the vertical posts can swing forward (toward the diagonal struts) such that the diagonal struts and posts fold down to lay nearly flat.
