The capacity of thelathe is from 28 to 42-in. wheels and itprovides for axles having either outsideor inside journals. The driving mechanism is cleverly de-vised. It is really a short lever pivoteda little nearer one end than theother. The pivot casting being carriedon the face plate, can be moved fromor toward the centre of the lathe accord-ing as the diameter of the wheels to beturned, varies.
