ABSTRACT:
A truing lathe has its components mounted on a base. A pair of stands for holding the workpiece are mounted on the base. The stands have a pair of notches where the workpiece rests and is rotatable therein. An electric motor with a pulley head is mounted on one of the stands and below the notches so that the motor drive shaft aligns with the axis of rotation of the workpiece. One loop of a stretchable endless belt is slipped over the midsection of the workpiece while the other loop is stretched to fit around the drive pulley. The cutting bit is mounted on separate longitudinally and transversely moveable blocks so that the bit can be adjusted radially and longitudinally relative to the axis of rotation of the workpiece to machine the workpiece. The mounting stand and the way the workpiece is rotated results in minimal precession of the workpiece on the lathe to allow for a closer and truer machining of the workpiece. The lathe is compactly built and can be powered by batteries under field conditions to repair electric motors used in radio controlled model cars. The type of electric motor used to run the lathe is the same type of electric motor used to power radio controlled model cars. The lathe also can be used in the hobbyist's shop.
