I haven't worked on an iris in a long time but I can tell you there is an order to putting em back in. Some have tips that area bent, those being hte first n last leaves to go in facing oppsing directions, some have larger n odd shaped leaves indicating another order. Trick is to find that order... look at the diagrams very closely for oddities.

Lubricating LF shutters is also tricky. Some shutters have factory coatings that shouldn't be washed n others need the slightest amt of the lightest oil you can find or run completely dry.

So play with it, be carefull n delicate n when you are feeling frustrated, jsut put her aside till tomorrow, answers come to you in dreams.

That is an amzing site. I discovered it by accident n have been exploring for quite some time n each time I find something new.
