I have made a master toe from acrylic and some filler, then I sanded it to a smooth finish.
On the right is the finished master toe, then its cast in fast cast resin. And the silicone mould on the left. Later I will cast 4 identical toes, 2 for each foot.
The body was carved out of a medium density foam. Then it was primed various times until a smooth finish was obtained. Later I will cast it in resin, to make strong solid piece.
The lens was made from a clear acrylic, thick rod. Worked on the lathe, sanded to its appropriate concave shape and then polished to a crystal clear glass look.
To make the droid's optical eye, I used a piece of chemi-wood. Here is how I prepared it for the lathe. First I made a square rod, then I sanded away the corners of the rod in the belt sander, enough to fit it on the lathe.
From the square rod, I made a round solid rod.
At this stage I had cut some depth into it, with the same width as the lens too fit it later. I have also made a hole in the centre, and now I will start working from the inside out. Creating various steps looking like an optical lens.
After working on the lathe. At this stage, I have also sanded it to a smooth finish.
Later i'll be using glues and filler to join all bits together.
