You have come to the right place for help with your lazy susan. FastJeff can supply a wealth of information on Lazy Susan alignment and, of course, the all-important timing. There are a number of experts who can help you with refinishing your susan and of course with the recommended bottom job - normally an application of sheet cork or felt. Very tricky, you don't want to attempt this without the benefit of experienced advice. I, of course, maintain a database of Generic Lazy Susan Wiring Diagrams, and I should be able to provide a diagram that suits the rework for your susan. And, don't forget to read the sections here on electrolysis, a very important aspect of any kitchen installation.
We wish you the best of luck with your project.
