Hi, I'm a newcomer who, because of accidental acquisition of a Tree mill, may be seeking advice from members of this forum. I am a retired design engineer and physician who currently invents tools. I've only done a little bit of metal turning but jumped at the chance to buy a lathe and mill that a friend was selling. I intended to keep the lathe and offer the mill, a Tree 2UVR-C tracer, to another friend who wants a full-size mill. He liked the mill but couldn't find space in his garage for it - since his garage is occupied by tablesaw, welder, metal lathe, mill-drill, tool cabinets and a Piper Cub that he's restoring. Therefore, I found myself the owner of a huge milling machine I've never used.
My initial question is: what are those round feet or leveling pads that I've seen in the photos of a few Tree mills. They seem to be inserted in the 3/4" diameter holes at the corners of a mill's thick base. "Stinson Voyager" Bill, for example, shows them in the photo of his installed Tree mill. The feet are not evident, though, in the photos that show him sliding the mill off his trailer and moving it into his garage. I've seen another Tree mill with identical-looking feet on eBay. Most used Tree mills, however, don't seem to come with them. Are these standard feet/leveling pads made just for Tree machines?
