Cleaning up mono-tube lathe
A friend gave me his Craftsman mono tube lathe to pass onto another friend. The lathe has been replaced by a NOVA DVR XP.
My friend mentioned the lathe was noisy and the tailstock difficult to move. I think some of this was a lack of maintenance.
Before sending this on I decided to cleanup the decades of dust, and see what else may need tuning up.
The tube had not been lubricated for awhile, it had small dings and scratches. No wonder the original owner friend complained of difficulty in moving the tail stock.
WD40 and some wet-dry paper to the rescue. In a few seconds all was working smoothly again.
Removed the tailstock and cleaned up the threads. Another part of the lathe which was overdue for lubrication.
Lots of old dust to remove, especially in the motor. An open drip induction motor is going to collect dust from a lathe. A consequence of the inexpensive price point of the lathe.
The pulleys had slipped over time. I had to use a pulley extractor to get them off The lathe pulley had slipped off sufficient the locking screw was not engaging in the machined flat section. It was now on the round section of the shaft.
After re-aligning the pulleys, I re-mounted the motor, attached the belt, and powered up. It is now running as good as new.
The original owner friend commented the lathe was noisy and vibrated a lot. I am not going to try any turning, but I do not feel the no load sound is noisy. I can just hear the hum of the motor.
Perhaps my friend needed to have cleaned this more often.
Good luck with your lathe. I would not want to use my friends lathe even though now running smoothly. The handles are too small.
