We use FreeCAD’s Part Design Workbench to model a Flanged Pulley shown at the beginning of the video. This video is the same as Tutorial 05 but with a few fixes and with audio added. The index is below (click “Show More”); if you have any questions or comments please post them in the FreeCAD forum, https://forum.freecadweb.org’ Please note that before your first post is actually published it must be approved by a moderator.
This tutorial was done using the FreeCAD version 0.14.2370 for Windows XP. Newer FreeCAD versions have since been released, so your version should have all the tools shown in this tutorial.

In this video I show you how to use a common bolt extractor to remove sheared fasteners from their threaded holes without damaging the threads.
This is a relatively simple process but I outline choosing the proper extractor and hole size, choosing the proper bit, and cautions when dealing with blind and open holes.
The broken fastener is a splash shield fastener on a Honda Accord.
But the techniques shown here will apply to removing broken fasteners from any threaded hole with a broken bolt.
