Damage to machined surfaces should be repaired with an oil stone. Test by hand to ensure smooth operation of all parts before use. -
Page 15: Lubrication
Lubrication We recommend the use of two lubricants on your lathe. • Where oil is required, we recommend Mobil 1 synthetic motor oil. Mobil 1 far exceeds the lubrication needs of the mini lathe and maintains a good surface film between applications. -
Page 16: Adjustments
Adjustments Keeping your lathe in adjustment is an ongoing process. You should check all the following adjustments when you set up your lathe and then periodically as you use your lathe. Looseness in the carriage retaining plates or the gibs can cause chatter when you are using the lathe. -
Page 17: Cross Slide Gibs
Cross Slide Gibs A gib is a strip of metal placed between the bearing surface of two machine parts to ensure a precision fit and provide adjustment for wear. The mini lathe has gibs in several places, including the cross slide. To adjust the cross slide gibs 1. -
Page 18: Compound Rest Gibs
Compound Rest Gibs The compound rest also incorporates a gib for adjustment. To adjust the compound rest gibs 1. Loosen the three lock nuts on the side of the compound rest. 2. Slightly loosen all three setscrews on the side of the compound rest. 3. -
Page 19: Tailstock Position
Tailstock Position The tailstock is adjustable from front to rear so you can align it with the spindle. To adjust the tailstock position 1. Remove the 3-jaw chuck from the lathe spindle. 2. Put a #3 Morse taper dead center in the spindle. 3. -
Page 20: Half Nuts
Half Nuts There are two adjustments for the half nuts. The half nut gibs take the play out of the half nuts. The half nut closing limit stops the half nuts from closing too tightly on the lead screw. To adjust the half nut gibs: Tighten the three setscrews in the back edge of the apron to remove play from the half nuts. -
Page 21: Overview Of Lathe Operations
Overview of Lathe Operations Basic Turning Before starting the machine as described above, it is check that the setup for the type of work to be carried out is fully checked. The following notes are guidelines as to how to set up the lathe to carry out a simple turning operation. - Page 22 When satisfied, retract the cutting tool, and crank the carriage/saddle away from the headstock, then crank the cutting tool up to the work along the length to be cut while rotating the work by hand using the chuck. Continue to advance the cutting tool slowly until it just touches the surface.
-
Page 23: Manual Turning
Manual Turning Follow these steps to turn the outside diameter of a workpiece. To turn manually: 1. Put a tool bit in the tool holder and adjust the cutting edge to center height. 2. Angle the tool so that the front cutting edge forms an acute angle with the axis of the workpiece, as shown in the illustration below. -
Page 24: Turning With Auto Feed
Turning with Auto Feed The mini lathe incorporates a power carriage feed that can move the carriage either direction. This same power feed is used for turning and threading. For turning, the change gear train is configured with 20 tooth gears in positions A and C, and 80 tooth gears in positions B and D. -
Page 25: Bevel Cutting
Bevel Cutting Bevel cutting involves the use of the compound rest, which is mounted on the cross slide and set at right angles to it (indicated by the zero mark on the body of the cross slide) for all normal cutting operations. To set the compound rest so that the cutting tool will cut a bevel, first retract the slide until the two socket head screws (A) are revealed as shown in Fig. -
Page 26: Facing
Note: Depth of cut is vitally important and may be calculated or obtained from an appropriate reference manual. 3. Take all necessary precautions previously stated and start the machine with the automatic feed lever in its' disengaged position (UP). 4. Engage the auto-feed lever sharply, turn the forward/neutral/reverse lever switch to 'Forward'. -
Page 27: Turning Angles
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. -
Page 28: Changing Chuck Jaws
Changing Chuck Jaws 3-Jaw lathe chucks come with two sets of jaws. The standard set is called the inside jaws, because the stepped side is designed to fit inside of hollow workpieces and hold by an outward force. In many cases, however, these jaws are used to clamp on the outside of smaller objects using the long straight side. -
Page 29: Grinding Tool Bits
Grinding Tool Bits When you purchase a new lathe tool bit, it might have an angle on the end, but it is not properly sharpened for turning. Grinding lathe tool bits is a bit of an art. It takes some practice to get good at it. -
Page 30: How To Grind Tool Bits
How to Grind Tool Bits Use a bench grinder to sharpen your tool bits. Even an inexpensive bench grinder can do a good job grinding lathe tool bits. In some cases, you might want to purchase a higher quality fine grit wheel. Keep a small cup of water near your grinder. -
Page 31: Tool Post
Tool Post The tool bits are held securely by the tool post. This mini lathe comes with a four sided tool post that can be rotated so that more than one tool can be secured for use and you can change between cutting tools as needed by loosening and then retightening the top lever. -
Page 32: Changing Gears For Cutting Threads
Changing Gears for Cutting Threads The lathe gears drive the lead screw by a gear on the spindle. The gear ratio will determine the rotational speed of the lead screw with relation to the spindle, i.e., one turn of the spindle will turn the lead screw an amount determined by the gear ratio. The series of gears that drive the lead screw are called change gears because you change them to achieve different ratios, impacting the leadscrew, resulting in different possible thread pitches when cutting. - Page 33 The change gear charts (see below) shows the thread sizes that may be cut using different gear configurations shown in corresponding columns. The actual thread produced will be totally dependent upon the profile of the cutting tool. It is not within the scope of this manual to provide detailed information regarding types of cutting tool, cutting speeds, and working with various types of material etc., and it is strongly advised that you consult appropriate handbooks or seek advice from a qualified person.

Gear Threads Per Inch Gear Chart for Cutting Metric Threads (mm) With a lead screw designed for TPI threading, you can also cut American Standard Metric Threads. -
Page 35: Threading Dial
Threading Dial When cutting screw threads on a lathe, you must make multiple cutting passes to cut the threads to full depth. The threading dial helps you align the cutting tool with the emerging thread before you start a cutting pass. The gear on the bottom of the threading dial's shaft engages the lead screw. -
Page 36: Threading Process
Threading Process It takes several passes to cut a thread to full depth. You must follow the correct procedure during each pass to ensure the thread is cut correctly. Use the power feed forward/neutral/reverse lever to engage the lead screw drive. The carriage should move from right to left (toward the headstock) to cut right-hand threads, or from left to right (away from the headstock) to cut left-hand threads. -
Page 37: Compound Angle
Compound Angle Set the compound rest at a 29.5° angle from a line perpendicular to the axis of the lathe. This allows you to advance the tool with the compound rest. At this angle the tool cuts only on the left side of the thread form. -
