    Sheraton 9A Headstock Lapping

    The Sheraton 9A is close cousin of a Southbend 9A, and a close copy of the Hercus 9A both built in Australia. My 9A #1167 was purchased in 2007 and operated successfully for a couple of years. I read all the books and diligently kept a good supply of oil up to the headstock bearings. I taught...

    Centering With Low Tailstock

    Hi, My lathe has a significantly low tailstock, perhaps 0.15 mm close to the spindle with minimum tailstock extension. I intend to correct it 'one day', but in the interim I would like to progress a few jobs requiring centres (like 5 inch gauge axles). It seems to me that the orientation of...

    South Bend Class Lathe Spindle Bearing

    Hi, First post by a new member. I have (in Sydney Australia) a close relative of a South Bend 9A lathe with bad bearings in the spindle. It is a Sheraton, made in Melbourne, with spindle running in the cast iron housing. Housing is single bolt closure onto a solid aluminium shim. Spindle not...
