If you are using it in a workshop, other machines should not interfere with the operation of the lathe. Lighting: Your room or workshop should have adequate lighting. The work area of the lathe should be well lit and there should not be shadows cast upon your work. If possible, locate near a window.
Assembling the Nova Comet II Wood Lathe: Caution: Care must be taken when handling the spindle threads. The spindle threads are sharp and should not be used to lift the lathe, to stop or manually rotate the spindle. Nova Comet II Components after Unpacking Qty.
1. Unpack the lathe and its components from the shipping package. 2. Clean any parts coated with the rust preventative compound with a cloth moistened with a petroleumbased solvent or cleanser, such as Kerosene or Mineral Spirits. After all the parts have been cleaned, coat the lathe bed with paste wax or a dry silicon spray. 3. Insert the Tool Rest into the Tool Slide and secure it with the lock handle. 4. Assemble the Tailstock Handle and quill lock as below. 5.
Adding a Bed Extension: Each cast-iron Bed Extension adds 24.6”/625mm to the lathe's length. 1. Clean the joining ends of both bed sections with a petroleumbased solvent. Make sure there are no dents or burrs on either of the mating surfaces. Remove burrs and high spots with a smooth file. 2. Place the two mating faces together and install the Four M10 cap screws. Note: only install finger tight at this time. ! Warning! Do not use a metal hammer to pound on the Bed Extension.
Using the Nova Comet II Wood Lathe: The Variable-Speed DC (Direct Current) Motor ! The DC motor contains brushes that contact the commutator. It is very important to allow between 30 to 45 minutes of 'run-in' time of these brushes before any turning or significant load is applied. This should be done in the higher rpm range. A clicking or swishing noise in the motor is normal which will reduce as the brushes wear in. During normal operation, 5 minutes of warm-up may also be required on cold weather days.
Direction of Lathe Rotation: The “ON/OFF” toggle switch on the motor controller has three positions. “ON Forward”, “OFF” and “ON Reverse”. To use the lathe, the switch must be in either of the two “ON” positions. Changing Speeds: 1. When starting, set the Variable Speed Knob to about ¼ of the speed range and slowly increase the speed to the desired RPM. 2. Starting the motor at the lowest possible setting may cause it to fail due to loading.
Headstock: The Headstock houses the motor pulley, headstock pulley, bearings, a belt and the spindle. The Headstock Spindle accepts centers and accessories with an No. 2 Morse taper (#2 MT). The thread size or pitch is 1" 8 TPI, RH. Using the Spindle Index: The Spindle Index Lock is located on the back of the Headstock. This locking system works by inserting a pin into one of 12 notches, 30 degrees apart, in the pulley attached to the spindle.
Mounting a Faceplate or Chuck: 1. With the lathe turned “Off” and unplugged, use the Spindle Index Lock to hold the Headstock Spindle in position. 2. Install the Faceplate or Chuck onto the spindle threads. A spindle washer may be used in between the Faceplate or Chuck to make removal easier. ! Warning! The Faceplate or Chuck body must contact the shoulder on the spindle bearing. 3. Disengage the Spindle Index Lock before turning “On” the lathe. 4.
Tailstock: ! Warning! Never loosen the Tailstock Quill or Tailstock while the work piece is turning. 1. To move the Tailstock along the bed, loosen the Tailstock Lock Arm, slide the Tailstock to the desired position, and tighten the Tailstock Lock Arm. 2. To move the Tailstock Quill in or out, loosen the Quill Lock Knob and turn the Hand wheel clockwise or counterclockwise. Lock the Quill in place with the Quill Lock Knob. 3. The Tailstock Quill accepts centers and accessories with a No.
Using a Drive (spur) Center: 1. Mark centers as shown in the adjacent drawings. Mount the Drive (spur) Center to the work piece as shown and then insert the Drive (spur) Center and work piece into the Headstock Spindle. ! Warning! Do not pound work piece onto the Drive (spur) Center while it is mounted in the Headstock as you may damage the Headstock. For hardwoods drill centers and saw diagonals for spur drive center 2.
Maintaining the Nova Comet II Wood Lathe: General Maintenance: Interval Maintenance After each use: Clean the work area and lathe. Vacuum scraps and dust from the inside of the Headstock, between the Lathe Bed Rails, and under the Tool Slide and Tailstock. Do not neglect this especially if the work piece was 'green' with excess moisture. Failure to clean-up after green turning can cause rust marks and pitting of the surfaces of the lathe.
Cleaning the Tool Slide: If the Tool Slide becomes hard to move and adjust, cleaning and lubricating is required. 1. To make the Tool Slide move freely along the bed, make sure the Bed Rails are clean. Apply some paste wax to the Bed Rails. 2. If the Tool Slide is hard to move towards or away from you, remove the Tool Slide from the lathe bed. Clean the Tool Slide Camshaft (round eccentric rod) with a petroleum-based solvent. Lubricate the rod with a light-weight oil or a dry silicone spray. 3.
Belt Replacement Procedure Note: the belt used on the Comet II™ lathe is a Poly-vee belt Overview: 1. Remove all accessories, handwheels, chucks and faceplates etc. 2. Loosen motor mount and take the belt off Pulley 1. Let the belt rest on the outer tracks of Pulley 2. 3. Unscrew the grub screw from the middle track of Pulley 2.
4. Remove Circlip 1 from the Spindle. 5. Knockout tool requirements: The knockout tool can be any round shaft less between 14mm & 24mm (9/16" & 1"). An ideal knock out tool can be turned to dimensions in drawing to right. 6. Using the knock out tool and a small mallet or hammer, tap out the spindle from Spindle end A until Spindle end A is approximately 15 – 20mm (3/4”) from the inside of Bearing 1.
7. Remove the old belt and place the new belt over the Spindle End A and on to Pulley 2. NOTE: Make sure the new Belt and Pulley 2 are all on the spindle. 8. Using a wooden mallet or plastic hammer, start to tap the Spindle back into the headstock. NOTE: Before Spindle end A enters Bearing 1, double check that the new Belt and Pulley 2 are on the spindle. 9. As the Spindle end A starts to enter Bearing 1, move Pulley 2 back along the Spindle.
Troubleshooting Guide: Problem Possible Cause and Solution Excessive vibration. Out of balance, or large work piece. Reduce the lathe speed to the lowest speed possible and turn the work piece to a true circle. Work piece is not held in the center. Check work piece mounting and correct. Work piece is not secure or held tight enough. Check work piece mounting and correct. Lathe incorrectly bolted to stand or bench. Refer to this manual for Lathe Stand recommendations.
Troubleshooting Guide Continued: Problem Possible Cause and Solution Tailstock and headstock center not lining up correctly: Bed incorrectly bolted to stand causing twist. Ensure stand and lathe are correctly assembled. Tailstock base is not flush with bed. Check for debris on both surfaces. Motor doesn't run: Check for compromised electrical cords. Remove plug from power outlet socket. Check an appliance that you know works in the power outlet socket.
