In this video I machine the crankshaft for the 1973 Yamaha GT1 to accept thrust washers. This is done on the Jet Lathe using a homemade turning adapter that performs off center turning operations. Once the material that is required to be removed (.040 per half), then the top of the halves are milled off in the Jet milling machine so the axial measurement can be made at the big end pin location. Then the crankshaft halves are finished with a die grinder to shape the location around the big end pin.
