In 2009 we made a DIY automated 360 turntable with the help of a few close friends. Since then I've used it pretty heavily for my 360º product photography studio. This particular one I made though is more suited for light products, like shoes and backpacks and such, but maybe parts of the design could help you out with building your own rig?
Also, in 2011 we launched www.imajize.com , which is a platform for publishing my 360 views on the web. Before I used it internally with my clients, but now it's open to the public. Feel free to give it a try!
Here are a few shots:
