If you use the search feature you will find that there are many discussions about building revolves. I believe some even have some drawings associated with them. If you can't find what you need with a search, then you will have to give us more details for us to be able to help you. Things like what show, how big a
revolve, what your budget constraints are, how long the run is,
etc.
Also, stop by the
New Members forum and introduce yourself, we love new people!
