Lazy Susan for Lazy Andy

My parents gave us a cool Lazy Susan made from the top of a wine barrel, so it matched our chandelier nicely. Unfortunately it had a small issue. The slab of wood had a bow in it, so the edges would drag when it was rotated, making it a pretty poor Lazy Susan.
The simplest fix was putting a thin spacer under the rotating assembly, so I fished some quarter inch plywood from my collection and cut a circle while my dad supervised.

The next and final step was to reinstall the spinner with some stainless steel screws of the appropriate length. For some reason, it was originally attached with self-tapping sheet metal screws.
