No hobbing or grinding required. It only shrank a little bit but it will be OK. Aluminum works as good as steel doesn't it?

All joking aside, it would make a good desk paperweight. Small lighter duty parts have been made this way for centuries though. Basic sand casting 101. The pattern part would have to be slightly larger to get it to be the size needed. Some patterns are just wood carvings. Charlie Sorenson did pattern work when he was hired by Ford.
