I'm always looking for an engine lathe or turret lathe or a lathe that can do engine sized work. A turret lathe has a rotating turret with any number of tools to swing into position. This is mostly for manufacturing where tooling changes would slow down the production line. So a turret could be set up to drill, bore, face and part a piece without a single change. One-off parts don't really require that kind of efficiency, but nobody would complain about not having to change tools all the time.
