Quoted from FiatsRUs:
I just purchased a Time Machine in pretty decent shape, but it had no cover on the right ramp. Here are some pics of one I made from plexiglass. I cut the basic shape with a rotary saw blade mounted on a dremel tool. I then completed the shape using a sanding drum on the dremel. The edges were sanded and then flame polished. I used an electric heat gun to make the bends and put a slight "hump" in it over the ball path so the balls don't get stuck. I saved the template if anyone is interested.
Also, at the far left of the third picture you can see one of the ball gates at the top of the playfield. It was missing the wireform and I couldn't find one at any of the usual sources so I made it out of a bicycle spoke. It worked quite well since a spoke is springy steel that can be bent, with some effort, without breaking.
