The rules of the Sign Challenge competition require that our pieces be shipped in a two foot by two foot box and then be pulled out and displayed on top. Rather than drape the box I decided to make it a part of the display. To maximize the size of the centre piece it meant the walls of the box needed to be as thin as possible. Steel construction was the obvious answer and with our MultiCam CNC plasma handy the job was easy.
The files for the box were designed using EnRoute. The stars were drawn using the star creator. Nothing could be easier. I decided to use quarter sections of pipe for the corners with the radius to the inside. The cutting of the steel plate took less than a half an hour. To weld all of the pieces together and grind it all smooth took about sixteen hours. It looked great already but the magic was yet to come.
