Interesting that there is no mention of Vicmarc lathes in this discussion. The VL240 with an extension bed would more than meet your expectations. Even the new smaller VL150 lathe which I have purchased will do all that you mention, or perhaps the VL175 is more the target size. Both the VL175 & 240's have rotating headstocks.
