Brian, the lathe stand was the creation of Phil Soper. I think he built it from rough sketches and ideas in his head. Unfortunately, no formal plans currently exist. However, I have committed to create the plans in SketchUp in the near future. As soon as they are available, we will place them in the "Download" library on this site, and make an announcement to let everyone know they are available. You are not the first person to ask about the plans, so we definitely want to make them available.
