Smaller, lighter-weight airplanes such as antique, experimental, and light sport aircraft can use lighter-weight propellers made of wood. A wooden propeller can be not only a functional part of the airplane but also a work of art.
Alaina Lewis and her brother, Grant Smith, craft a variety of wooden propellers at their family-owned business, Culver Props, in Rolla, Missouri. Their grandfather and parents bought the business in 2001 and Lewis and Smith first helped in the shop, then graduated to making propellers themselves. Using patterns collected over decades, Lewis designs propellers according to customers’ measurements, chooses the wood—usually hard white maple or mahogany—glues the layers of wood, cuts out a rough draft, puts it in a lathe to do the precision cutting, and sets the pitch. Then she sands, balances, and repeats those steps until the blades are perfectly balanced horizontally and vertically. After a protective coating and a 10-day curing period, the final touch for the propeller is a Culver Props sticker. FT
