Looking for an open source 3d cad solutions? IO Rodeo designed their water channel project using openscad and their py2scad python scripting plugin for openscad. Tux-Lab has the much simpler task of just machining a few parts. One of them was the pillow block mount.

The gcode was fairly simple and consist of three operations. Lesson learned was that a properl sized drill will be faster than using an endmill to mill the hole to size.

Completed 14 sets of aluminum cylinders for IORodeo's Pendulum sensor kit using the Haas TL-2 cnc lathe. The use of the gang tool allowed for the drilling and tapping operation to be completed with the lathe. A video of the process can be found on youtube.
