Sorry it took me so long to post. I was wanting to have more done, but......
Anyway, the box is made from wood baseboard, which was simply mitered and glued. The copper top will rest on 3/4" MDF. The holes for the copper top are drilled to size, and the corresponding holes in the MDF will be drilled out much larger for more working room. The copper and MDF will be glued together and will rest on supports that are glued to the inside of the box.......Colin
