Thanks Guys,
Afraid I can't take all the credit for the box. I cut the ally on a guillotine and used a band saw for the cutouts, cleaned the edges to the scribe marks with a sander, then bent it in a V block on a fly press (thanks to a local machine shop). The TIG work was done by a professional (I am OK on SS but you would not want to see any of my ally TIG work

).
Let you know about the thin foil Dan when the project is finished.
Right on Sam but did you know that CO2 lasers are, apparently, better at burning corneas than they are at retinas because eyeballs are quite opaque at the far infrared (not that it makes that much difference though).

Tweakie.
