Turning 

 

The lathe can be used to reduce the diameter of a part to a 
desired dimension.  

 

First, clamp the workpiece securely in the lathe chuck. The part 
should not extend more that three times its diameter.  

 

Then install a turning tool (whichever is appropriate for the 
material). 

 

If you're feeding the saddle toward the headstock, use a right-
hand turning tool. Move the tool off the part by backing the 
carriage up with the carriage hand wheel, then use the cross 
feed to set the desired depth of cut.
