My first Mechanical Iris

Hello Guys, this was my first attempt  into a mechanical iris, it was a very fun project, inspired on "gogglerman" creations.

The outside ring (red ring) is made of 3 mm MDF, it has a 130 mm outside diameter, and, an 75 mm interior diameter.
The ring was cutted with holesaws.

The back plate (silver round plate) is made of 12 mm MDF, the runners on it, were made with a tablesaw. it also has the 130 mm outside diameter.

The leaves are made from aluminized sheetmetal.
Bicycle spoke nipples were used as pins, they were brazed to the sheetmetal.

And finally, the whole assembly was housed in a cd tube case.

Thanks for watch!
