If you are interested in this see the page with the discussion on the copper aging over time.
Step 1: Tools and materials
Glue (I used TC-20)
Wood for clamping (I used 2 2x4's)
Small piece of flat wood for bending.
Tools you'll need:
Clamps (at least 4)
Sheet metal brake
Sandpaper for metal
Ink/glue roller (optional)
Some people use a common adhesive like Liquid Nails but I used TC-20, a copper adhesive from www.veneersupplies.com. It's more expensive (~$25 w/ shipping) but compared to the cost of the copper it's not much.
