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. If it fails, check the breaker/fuse in breaker/fuse box 
corresponding to that socket. If socket is operating, then the Control 
Unit of the Comet II Wood Lathe may have failed. Contact your nearest 
service center  for a replacement.   

Tailstock hand wheel 
hard to turn or will not 
turn: 

Quill lock may be  locked. Unlock the Quill Lock.  If necessary, lightly 
tap a block of wood against the Hand wheel Handle.  Tap the handle in 
a clockwise direction as viewed from the Tailstock end. 
Build-up of dust and/or wood resin on the Quill or inside of the Hand 
wheel thread. Remove, clean, and lubricate the Quill and Tailstock as 
described under "Cleaning the Tailstock".   
The Quill has been retracted too far and is locked against the Hand 
wheel.   

Tailstock quill  
hard to move:  

Quill Lock may be  locked.  Unlock the Quill Lock.   
The Quill may be  damaged. Turn the handle to expose the Quill and 
check for marks along the Quill, especially on the edges of the slotted 
keyway.   Remove any high spots with a smooth file and test the Quill 
travel.  Replace the Quill, if necessary. 

Tailstock not sliding 
smoothly on bed ways: 
 

 
Dirty bed ways and underside of Tailstock Body. Clean bed ways and 
underside of Tailstock Body with a petroleum-based solvent. 

Tailstock binds: 

The inside of the bed has a high spot.  File the area with a smooth flat 
file until the Tailstock moves freely. 
The Tailstock Adjustment Plate has a rough spot or a burr.  Remove the 
Tailstock and file the Plate with a smooth flat file. 

Tailstock jumps where 
bed sections join: 

The machined flat surfaces are not flush.  File the area with a smooth 
flat file until the Tailstock moves freely.
