I don't think people realize that it's a piece of history!! They don't make those in America anymore, and not only that, they don't make 'em to last either!! it would be a pity to scrap it out.
I just found out my lathe was build around 1925, it would be impossible to replace! As for needing 3 phase, get a 5 horse drive, that will convert single phase to 3 phase. here's a picture of my lathe it weighs about 700# i would guess that planer would weigh at lest 1000#
