Abstract: A system is disclosed for simultaneously and more efficiently setting the stroke position of a crankshaft on a crankshaft lathe and a method of using the system in combination with the lathe for regrinding, building-up by welding or other machining of journals of the crankshaft. The system includes slide blocks and slides in operable combination with rack and pinion gears means for simultaneously positioning the crankshaft from a zero loading position to an offset position transverse to the longitudinal axis of the lathe.

Abstract: There is disclosed a machine for successively applying weld metal to the journals and crankpins of an automotive crankshaft, by rotating the crankshaft on its axis, and employing a means for causing a weld metal feeding torch to follow the crankpin around its circular or planetary path travel, depositing a bead of weld metal on the crankpin. The torch is also translated along the crankpin, and a bead or beads of molten metal is or are then wrapped around the crankpin, preferably in a succession of adjacent circles, and welds thereto. The layer of weld metal thus added is subsequently machined to its proper dimensions.
