December 12, 2020 Update: This week, at long last, I finished my CNC mini-router! The spindle motor is a little under-powered, and the machine is not as rigid as I would have hoped, so its actual usefulness is going to be rather limited, but it actually works! Really, the point of this project was mostly just to see if I could build a CNC machine from scratch, so in that regard it was a success. I also managed to edit the video about the CNC router today, so that accounted for most of what I did this week. This weekend, though, I think I will upload a video I made a while back about an interesting shotgun slug that I attempted to make.
