Making new fingers to human proportion

These are the new fingers that I am making for the robot. They are made of 1/4 inch thick plexiglass. I used a penny and a nickel to draw the curve of the plastic on the fingers where the joints are. So far I have completed the two index fingers and I will be working on making more fingers tomorrow. I have tried to base most of the proportions of the robot's hands off of my own and so far everything is coming out very well.
