Nice project if you have a mill and a dividing head. 3 phase - converter not included. Included in the sale but not on the pictures - back splash guard, safety guard ( needs new Perspex, going a bit opaque).
NO LEADSCREW - just the nut! (leadscrew only shown in photos 1 and 2 for reference). Tested in a 10tpi, 1/2" OD across thread leadscrew from a 11" lathe, and it was an excellent tight fit. I don't know if it's an original part however - as per first two photos, the hole isn't parallel with the sides.
MODEL L5A (11"). MODEL L5 (9"). PDF COPY of the Harrison Lathe Operation, Installation & Maintenance Manual, including pictorial parts lists. MODEL 140 1400mm (11"). The manual has 79 pages. All geared head.
