Been cleaning up the 1963 Chipmaster lathe. 60 years of neglect and dirt / crud . Disassembled the headstock - not many parts in it. Complicated front spindle bearing which costs a fortune to replace . A ring of small springs on the rear spindle bearing provides the bearings preload . Evidence of badly leaking O rings and oil seals . Spindle bearings are oiled by a tubular trough high up in the headstock that has tiny holes each end that drip oil onto each spindle bearing - often the holes are clogged with crud . I hope it all goes back together OK !!! There is a Chipmaster Facebook group for anyone neediing assistance . The QCGB assembly is very easy to remove , a 5 minute job. Hex socket head screws are used throughout , these are all UN standard threads which is nice ! Little evidence of wear on everything , the bed is in good shape.
