Then comes the time when a plastic piece will surely leave you high & dry, especially where high heat is expected weather inside & outside at the same Time is a malfunction ready to take place. But to make our own parts better & which will make our things last a whole lot longer is a good way of knowing if we can do this, we can make our own. Not that my comment will mean much, but I think plastic use has outlived it’s purpose, especially when using metal with plastic is a failure that these makers of products enjoy failing at to profit in our failure to hold them responsible. Posted in News, Repair Hacks Tagged freecad, gears, plastic gears Post navigationĬan’t wait for the day plastic gets replaced for good! If some other material other than plastic was used for making 3-D parts, I’d be more into this more. We’ve placed all three videos below the break, and we think you might want to make yourself a cup of tea or something and work through them. You might ask why not machine it, to which he responds that tooling for non-standard gear profiles is prohibitively expensive. He shows how this software removes the complexity of creating a gear, and shows the process on his screen as he creates the custom shredder part.įinally, the process of 3D printing the gear is explained. His tool of choice is FreeCAD, and while he explains that FreeCAD has the ability to make gears from scratch the tool employed in the videos is the Gear Workbench plugin. How to measure the parameters of a given gear, explaining mysteries such as pitch angle or beta, he breaks everything down in easy to understand steps. While the principles of a gear are readily apparent to most observers their intricacies hide significant complexity which he does a great job of explaining. He’s posted a video series over three parts that while ostensibly about fixing his shredder, is in reality a three-part tutorial on how to create custom gears using FreeCAD. has a shredder with a gear that has, well, shredded. This is a problem particularly with plastic gears, which shed teeth faster than a child who has discovered the financial returns of the Tooth Fairy. It’s very likely that a majority of readers will have had a gear fail in a piece of equipment, causing it to be unrepairable.
