It took me a year and two machining courses, but it's finally ready. My first motion control project.

I have finished my dolly prototype. Well almost. The shaft/pulley connection needs some attention, but that is under control. This dolly is not perfect; I also use it to test some of the mechanical ideas that I have for future projects.
You can find a very long and detailed description of the dolly on my blog:
