The copper is only about 1mm thick so it needed a support to hold it up and also attach it to the frame. I got some 18mm (3/4 inch) plywood and cut a piece 1000mm x 550mm and cut some strips about 75mm (3inch) wide. I glued and screwed these strips around the edge of the top to make the top seem thicker.

Hammered effect

The hammered effect in the copper is simple to achieve, it just takes a lot of stamina in your arm!! You will need a ball pein hammer to get this effect and it is simply a matter of hammering the copper! You will get a feel of how hard you need to hit it after a few goes.

Attaching the copper to the plywood.

After my arm had recovered from all the hammering I stuck the copper to the plywood with some strong silicone. I used Tec7 . After applying the silicone I added some heavy weights to the plywood and copper to ensure any lumps were flattened out and that they bonded together correctly.

Folding the corners:

As I said earlier copper is a soft metal and pliable. The corners need to be cut to fold it properly so I set out some pencil lines of where to cut (see pics and video) and cut these with the tin snips. I then folded it as far as I could by hand and then using the flat side of the ball pien hammer hammered the copper around the corners as neat as possible. When I folded it around the bottom side I used some nails to hold the copper in place.

What finish?

I used a compound paste to clean the copper one last time. In the end I did not put any finish onto the copper as I want it to darken up and colour over time. To keep the shiny polished look a lacquer can be added .
