I built these for the shop bot challenge if you like them please vote!
From the start I would like to acknowledge Gogglerman for his exceptional work it was the basis for my desire to make these.
The whole process took at least 4 weeks at about 6 hours a day, I will not attempt to show all the work, but hope to explain how I made the super thin Iris in the goggles, the final product has an additional lens and filter which was not needed if you only wanted an Iris pair of glasses.

Signing UpStep 1The Iris construction
These shots show me thinking through the way to set up a thin iris, there are two rings one inside the other, as the outer turns it pushes the posts on the bottom of the shutters. The outer ring must have elongated holes because the pivot points move slightly away from the outside edge as the shutter closes.
I did not use an eight shutter design as I tried in the cardboard test model.
the pictures are proof of concept they are straight in the picture but will end up as circular in the finished product.
you can see from those pics the iris need only be 3 layers of metal thick. about 1/4 inch including the pivot posts.

Thank's for having a look.
Bravo!!!!!
the second pic in this step shows how the shutter action works.
Two protractors glued to a rotatable board greatly improved the accuracy of placing my noches in the rings and getting the shutter over-lap right.
I also used it to determine the 5 hole positions for the base plate.
I tried using dividers going around the circumfrence but could never get an accurate position for all five holes.
a thin sharpie is mandatory for layout, the card board mock up is very helpful in getting your dimensions and feel for the final product.
The way I used the protractor was to place a circular blank of brass sheet with a 3/16 hole in the center, then rotate the blank until I had the desired shutter length.
I will soon be posting a second iris which is simpler to make and easier to adjust.
My moniker is longwinters and it's a massive snow year here, so there was time to sit in the shop and built these monsters, you always wonder when you are building something like these, will other people like it? It is good to hear I got the asthetics pretty close.
Mostly I like the stacked sides that reminds me to the old Lincoln cars and I love that very much.
How did you get that pattern on the wire? Is that the same wire that´s bended around the saw in the picture?
The lower wires are a smaller diameter.
The way I made the pattern was to solder the tubing on a little long then sand them togeather to form the "spirial" looking design , this was repeated with each additional segment.
I chose to mount the exterior cover to the copper outer ring, it should be noted that when you operate the shutters you are actually rotating the interior assembly.
Thanks to all for the kind words!
Take a bow!!!
Absolutely great work. The iris mechanic looks really good. I am still longing for the right idea of my future goggles and you brought me another idea. Great;-))))
Keep up your style!!
