I agree with getting rid of the gingko.
If the table is using belt drive, consider three Still Points under the table, four Vibrapods under the motor. If using rim drive, get a good shelf system and place the motor / drive assembly on a separate sliding platform. The table and rim drive need to have a solid and stable point of contact. The table MUST sit on a solid platform that won't move. The rim drive must be on a surface that will only slide horizontally but yet have a solid, unwavering contact point with the platter.
