CNC Spindle using brushless RC motor

CNC Spindle using brushless RC motor

Originally discovered on buildlog (http://www.buildlog.net/blog/2011/09/new-brushless-dc-router-spindle), I couldn't find source files, so I designed them using openSCAD and incorporated variations based on the materials being used (10mm PE or Delrin/POM). I had the 4 parts milled on a CNC, with the top part needing two passes. It was easier to mill from the side of the bearing inset and then create the bottom pocket for the motor using drills for registration pins. This process took approximately an hour for 2mm layers on my CNC. For a 3D printer, it could take longer. I also refined measurements on lock blocks for tolerances; Heeks file is ideal for milling operations. However, adding gcode files depends on your machine's settings (mm or in) and speed (300-400mm). This project is still a work in progress, with more photos to come of the MXL pulleys assembled. Press fitting bearings can be challenging, and I'm unsure if a wave pressure washer will adequately preload them.
