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!

    I want to design an iris for something. None of the ibles I found actually tell how they designed the leaves etc. they just have a print and cut pattern. Can you show me how to actually design this? especially the shape and size of the leaves and the pin spacing, slot spacing.

    Could you please post a step by step on this? I'd LOVE to learn how to build this for my next Portal themed party!

    I dont have enough pictures of this build for a step by step, but now i will make a 12 leaves iris, and i'll take plenty of pictures for a step by step, so i hope to have the instructable for tomorrow.
