Cutting Procedures
The instructions that follow are basic operational procedures. It is assumed that the operator understands lathe operation and it’s capabilities.
1. Rotate Turn Lever (C) counterclockwise to move the saddle outward.
2. Place the workpiece in the chuck, center, and secure with the chuck key.
3. Loosen the Straight Lever (H) and then rotate the Turn Lever (I) clockwise to engage
the Dead Center tool into the end of the workpiece. Tighten Straight Lever (H) again.
4. Select the desired tool set and place it into the tool rest. Align the tool nose to the
spindle centerline, then tighten.
5. Open the Gear Box and verify that the proper
speed is engaged.
Typically, the harder the metal workpiece, the
faster the spindle speed.
6. Set the desired feed amount according to the
type of stock, workpiece dimensions, and the
type of cut.
7. Close the Gear Box.
8. Open the safety cover over the On / Off switch and press the green On button.
Verify that the lathe head and feed amount is correct.
9. Align the tool nose on the workpiece where the cut is to begin.
10. Rotate the Turn Lever (C) clockwise to move the saddle transversely, moving the tool
nose into the workpiece for cutting.
11. When the cut is complete, press the red Off button.

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.
6. When the cut is complete, press the red Off button.
Machining Cones
Manually
This operation is similar to machining cylinders with the following differences.
1. To manually cut a cone, determine the taper requirement and turn the small cutter rest
to the desired slope on the workpiece. Retighten the cutter rest.
2. Press the green On button to start the lathe.
3. Turn the Straight Lever (F) clockwise to make the cut.
Automatically
1. To automatically cut a cone, determine the taper requirement and turn the small cutter
rest to the desired slope on the workpiece. Retighten the cutter rest.
2. Horizontally move the tailstock from the spindle centerline to the required slope on the
far right surface of the work piece.
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.
5. Repeat steps 2 through 4 until the desired cone size is cut.
6. When the cut is complete, press the red Off button.
Machining Threads
The Gear Box is composed of the change gears, shaft bolt, fixing shaft bolt, and square
nut. The change gear box is fixed on the left support of the leadscrew (101). To cut threads,
select the proper change gears for the desired thread type (see Thread Formula Table), and
engage with approximately 0.1 mm tolerance. Tighten Screw (835).
SKU 44859
Page 7
The Fixed Shaft Bolt (825) under the spindle is used for right hand cutting and threading.
The set of Fixed Shaft Bolts in the accessory kit is used in combination with the original set
of Shaft Bolts to reverse the rotation of the long leadscrew for left-handed threading and
cutting.
The change gear for metric or inch threading is selected according to the Thread to Gear
formula and table. The feed amount depends on the material to be cut, the surface roughness, and finish requirements. If the two settings “0.1 and 0.2”, of the Gear table do not
meet the requirement, you can add or change gears. The same is true if the number of
teeth listed in the Gear table do not coincide with the calculated number of teeth. In this
case, use gears with similar number of teeth. In doing so, however, the following relationship of the driving shaft must be met: Z3+Z4+>Z2+Z5. Otherwise, the addendum of circles A2
and Z5 will hit each other.
The left formula below is an example of 0.3 mm spindle round. The right formula is an example for 8 threads per inch.
The Thread to Gear settings table on the following page allows you to select the number of
threads per inch or millimeter, and which gears need to be used.

Rest Accessories
The Follow Rest (not supplied) is mainly used for cutting long and thin shaft pieces to ensure no bending takes place during cutting. It also provides a better finish surface as a
result of less vibration. The Steady Rest (not supplied) provides a similar function as with
the Follow Rest. The difference being that the Steady Rest is fixed on the bed guides, and
does not follow the movement of the cutting tool. Both rests can be purchased from Harbor
Freight Tools.
