Famed choreographer, Busby Berkeley, was born on this day in 1895. On Broadway and in motion pictures his high-kicking chorus girls, doing the shimmy, shimmy, shake, made him famous worldwide. Today we're discussing another kind of shim --one that stops shakes and wobbles and helps make minor adjustments of all sorts. They are little strips and wedges made of wood, metal and plastic that go in small spaces and level everything from cabinets and furniture to equipment, machinery and plumbing fixtures. For centuries, shims have been essential in all areas of construction and everyday life. Ever sat at a restaurant table that's a "rocker"? Shims are useful, but they must also be able to carry the load we put on them. For minor light adjustments, wood is fine. To handle the weight of heavier stuff, use plastic or metal. Shims can be useful when things go shimmy, shimmy, shake. And that's the On The House tip for today.
