Introduction: Small Mechanical Iris for a Custom Sonic Screwdriver
I have been constructing a custom sonic screwdriver based upon the 11th (current) Dr. from the T.V. show Dr. Who. I decided to add a mechanical iris embedded in the pommel as a feature. So here are a few pics of the construction and finished pommel for the sonic screwdriver.
The cam is 20mm in diameter with a 10mm aperture. It has eight leaves that close to approximately 2mm
The inspiration was from the timepiece iris.
Thank you for looking.
We have a be nice policy.
Please be positive and constructive.
