To face with power feed:
1. Put a tool bit in the tool holder and adjust the cutting edge to center height.
2. Angle the tool so that the side cutting edge forms an acute angle with the face of the work
piece.
3. Move the carriage to the right so that the tool bit is past the right end of the work piece.
4. Turn the lathe on. Adjust the speed to an appropriate speed for the material and diameter you
are working on. The LittleMachineShop.com Web site has a calculator to help you determine
appropriate cutting speeds at

5. Using the compound rest feed handle, slowly advance the tool bit into the work until it just
touches the surface of the work piece.
6. Move the cross slide back so that the tool bit is clear of the diameter of the work piece.
7. Using the compound rest feed handle, advance the tool bit about 0.005".
8. Push left and then up on the power feed lever until the power feed engages. As the tool bit
meets the work piece, it starts cutting.
9. When the cross slide has moved as far as you want, lower the power feed lever to disengage
power feed. The cross slide stops.
Turning Angles
There are several methods of turning angles or tapers.
•
For large angles of short length, such as a chamfer, turn the compound rest to the angle you
want. Advance the tool across the work with the compound rest and advance the tool into the
work with the cross slide or the carriage.
•
You can use the same method for small angles (usually called tapers) of a length less than the
compound rest travel.
•
For longer tapers, the work is usually placed between centers with the tail center offset from
the centerline of the lathe.
Threading
Much of the mechanism of your lathe is provided to allow you to cut threads. Your lathe can cut a
broad range of thread pitches. In fact, with the standard change gears, you can cut many more
thread pitches than those shown on the table on the lathe.
