I have always been wanting to do that with some steel wheels, but haven't got Around Twuit yet, LOL
I have welded up and wired 6 of these. These two I have in my house. The other 4 I sold as custom lighting. They are made from dump rake teeth, side chain from tire chains and what ever else I could find. The globes are store bought and they can be mounted to uplite or downlite like these. Ceiling heidth and what the customer wanted determined the final look. It takes 10 teeth to complete the wheel so it looks correct.
