I hope I didn't already post this project.  I forget.  But if not, here goes.  I built two spark plug wire harness covers after I saw them on a few rods at a show last summer.  I used two flat sheets of stainless steel from an old bar-b-q and cut them to size and shape.  Then I found a style of font I like from the fifties from a site called 'Font Diner'.  I drew them out on Frisket paper to the size I wanted, cut them out with an X-acto knife, used the resulting stencil to ink them onto the metal, removed the Frisket and then finally engraved the letters in. The panels aren't as clean and shiny as new chrome but I think they turned out ok and there was so much fun in the building, I'm ok with the finished product.  On a sunny day, they still gleam.
