3rd Mechanical Iris With Very Thin Leaves!

OK! so today i made a new set of leaves for the iris, this time i made them of a very thin (0,1 mm) copper sheet.
The reason for the thin leaves, is to achieve a complete close of the iris, and the results were amazing!

On the pics you can see:

Pictures 1, 2 and 3 : The finished assembly
Pictures 4 and 5      : You can see the thickness of the copper sheet, 0,1 mm.
Picture 6                   : Fresh cutted leaves.
Picture 7                   : I find this the best way to soldering the leaves.
Picture 8                   : Finished leaves, i must said, these were very difficult to solder, but not impossible!
