More CNC’d parts

sprockets I have been playing more with my CNC machine and am working on some tiny treads for the GM10 motors. Here is a pick of the drive sprockets that I made. That is 1/4″ square grid paper that they are sitting on. I cut some prototypes out of nylon (yuck) then cut these out of some sample scraps of “Butter-Board“. That stuff cuts nice!
I made a female mold for the treads, but I don’t like it, so I’m going to redesign it. Maybe the sprockets also. I just got a 1/16″ end mill in the mail today so I can probably make them better now anyway. As soon as I tram my mill and get out the backlash, since my circles appear slightly out of round.
