So now that I managed to make a bearing idler for my DARwIn-OP robot clone, I have to produce enough for a whole robot.
I am starting with the Bearing Cap which is the easiest part to machine on a lathe.
15 Caps is enough for a basic DARwIn-OP robot.

Updated: The gcode cut programs are in the Code Section and zipped in File Section in sourceforge repository for cloning the DARwIn-OP Robot.
