Machining Cylinders

1.Repeat the cutting procedure steps 1 through 8, listed on the previous page.

2.Rotate Turn Lever (D) clockwise and move the saddle to the right of the workpiece.

3.Rotate Turn Lever (C) clockwise until the desired depth of cut is reached on the far right surface of the work piece.

4.Press down on the Straight Lever (G) to engage apron clasp nut over the Gear Shaft. The tool will automatically move from right to left while cutting the workpiece.

5.When the cut is complete, press the red Off button.

Optionally, you can turn the Reverse switch to have the tool go over the same cut in the opposite direction (left-to-right). This will clean and smooth the previous cut.

3.Press the green On button to start the lathe.

4.Press down on the Straight Lever (G) to engage apron clasp nut over the Gear Shaft. The tool will automatically move from right to left while cutting the workpiece.
