Build Your Own Hobbing Machine.

Amazing how some people can find the time to build these things.
Check out the clever way they've solved the differential problem.

Very clever design. However, I can't imagine any logical reason for going through the effort and expense to build your own gear hobbing machine other than to prove to yourself that you could do it. As the website noted, the quality of gears this machine is capable of producing is relatively poor. In our modern era of digital CAD models and 3D direct manufacturing processes, it is quite easy and quick to get a prototype gear of modest quality.

The web site shows herringbone gears and says they were manufactured with this hobbing machine. How can this be true?
