I have turned alabaster on lathe for about 4 years and on the bed side it seems to have developed a slight wobble. Its ok on outboard side. I have put some really heavy stones on lathe, ones that take 2 men to pickup. Was wondering if it could be bearing on bed side. Can't detect and movement. Is possible to get parts for lathe? hope someone can help. I am still turning stone, just have to be careful to not set rpms too high on large stone.
