Re: Using copper sheeting for Island countertop
I would hire an architectural sheetmetal shop to make the top for me. Multiple pieces can be joined with copper solder - not silver/tin as is used for plumbing connections - that way the joints become invisible. The shop can then bend the piece to fit your countertop dimensions and weld the vertical corners and seam the edges.
I would then install the prefab'd sheetmetal onto the countertop with contact cement so that it was solidly adhered to the surface.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
