Don't know if this will help. Some years back I did some. Used a metal clothes hanger. Shaped it into my neck size. The ends were two used up prescription drug containers. Drilled the ends and slipped metal and did a loop and then hot glued them in place. Then I just did rusted up painting to have them look like bolts. If you want to have them look more cool as some one suggested to me is I scrape some of the paint off and try putting those led candle setups to make them appear like you still have some spark in you.
