I finished casting all the required parts mid-July and moving onto finishing & painting. So far it's been a month of finishing all the cast parts by using metal filler and modeling primer to sand over imperfections, as well as using a rotary tool to clean up tiny details. I expect much less effort to be required for machined parts. No idea how much time painting will actually take after all the parts are primed & polished.

In other news, I presented this project to high school students at the Pacific Northwest College of Arts:
