Pottery Wheel Maintenance
It came to my attention that many people probably land on this page looking for a REAL pottery wheel maintenance guide. I myself from time to time run into wheel problem too. There are cases where the wheel pedal is too sensitive; the speed is not consistence; the wheel is making loud noise at high speed; and at one time, the electric cord seemed to leak power, and I got a mild electric shock while turning the wheel off (luckily, I didn't die from that...) I found some simple guidance regarding taking care of your pottery wheel from eHow.com. Here it is:
Clean up well, after every session, as clay gets everywhere. Clay is easiest to clean up while still wet, so try to make wheel cleaning a part of your normal maintenance routine. Pay special attention to the small space between your wheel mount and the spinning tray.
Wipe excess clay from the pedal of your pottery wheel when you notice that it is building up. A dirty pedal can be difficult to control and can lead to the destruction of your projects.
Listen to the motor of your pottery wheel; it should be almost silent. If you begin to hear humming noises, it's time for a good cleaning and oiling. Clay dust can build up inside the motor after a long period of use. Your local pottery supply shop should be able to tune up and maintain your motor for a reasonable price.
Cover your pottery wheel with a sheet or drop cloth, if you won't be using it for awhile. During prolonged periods of inactivity, you should plug in the wheel and work the pedal a bit, every month or so, to keep the motor maintained.
Unplug your pottery wheel, or turn it off if you have an on/off switch, when it is not being used.
