Iterations: A Wooden Pulley

2008 02 15 Construction 008

Today I worked on fabricating another two pulleys out of wood. I finished drilling well-aligned shaft holes in the side pieces and made new pulleys out of particleboard and plywood. The most time-consuming part of this process was cutting the circles out of with the bandsaw. I remembered that there is a jig for cutting circles, but didn’t want to spend time figuring out how to construct it in order to cut six circles. I first started by cutting around the contour of the circle, but ended up just making tangent cuts and then sanding away the excess. I was really trying to have another pulley finished by Saturday so I could test two of them with Wendy and Martha, but that doesn’t seem to be realistic at this point. I still have to make the encoder structure.
