Boring a ship's large driveshaft - photo

A couple sizes larger than Frank S's "pencil sharpener". But still far from largest of lathes. Those, you park a chair on the toolpost...not just leaning. That mans a slacker!
I ran a 48" Monarch periodically, for large round compression molds, like O-rings, but shaped like garage door seals, weather seals for some kind of hatch. Not as much fun, stood on the regular ol' floor.

Which one? Note carriage closer to headstock, larger yet, appears same size toolholder. Not QCTP. That bit looks 4" square and 30"+ long. At those dimensions, it weighs ~135 pounds. Not incredibly heavy, but without a good place to stand...

Large lathes, 20" swing and up, depending on the shops work, are best served by bridge or gantry crane. Loading with a forklift and slung material is a small nightmare in coordination. A smaller manual chain fall from main hook [or the rail, even better] is my favored type of manipulator. Powered types don't inch well.
