    Depending upon how adventurous you feel, you might consider driving the lead screw with a stepper motor instead of through the lathe gearing. You may find there's enough room at the right side...

    Just for reference, the thread in the tailstock ram is a left hand thread. Any turnbuckle will have a left hand thread on one end. Left hand threads are not all that uncommon. But cutting a left...

    Proceed with some caution. $1000 isn't a bad price for a 10L that's in good shape. However, from the pictures, the "frosting" that's on the ways does not look anything like the factory frosting. ...

    Oh yes! If those holes have not had screws in them for a number of years, there will be all manner of crud down in there. You will need to figure out a way to clean that out. Carb cleaner with the...

    Be careful because on my 10L (vintage 1940's) the screws and 10-32. Of course, a 10L is not a 13 so yours may still be something different.

    I NEVER use grease anywhere on any of my South Bend lathes. Grease has a tendency to pick up and hold dust, dirt, and metal chips -- not good for moving parts.

    First of all, the 10K bed ways are NOT the same as the 9 Jr. The 9 Jr. is a cousin of the standard 9" lathe from the same time period and a cousin of the Heavy 10 so far as the bed is concerned. ...

    You'd sort of have to say which lathe. My 10L had a South Bend branded chuck on it when I got it but it was worn and couldn't center anything better than .005 - .007 inches. My 1936 9" Workshop...

    Yes there is a significant difference between the two of them. The 10L bed is much wider than the 10K bed so there is no way a 10K tailstock can fit on a 10L bed.
