I've been a fan of the circuit board pen blanks since I first started making pens. I've made a few and have always been happy with how they have turned out. Now that I've been making pens for a few years it has become hard to come up with gifts to make for family members. One day while making another circuit board pen the idea of making a circuit board yo-yo came to me. I wasn't sure if I would be able to cut the circuit board with out them shattering. I started by removing most the components from the circuit board, and then I cut two circles on the bandsaw trying to keep the details of the board and some of the components that were flat to the board.
Next it was time to cast the boards into clear acrylic. I went with Amazing Clear Cast by Alumilite because it has a long open time which I hoped would allow for a blank with fewer air bubbles.
I made a video explaning how I made the yo-yo.
