Project: Pouring Cement and Installing Crown Molding

In Columbus, OH, Bob and other volunteers are constructing a playground. Bob discusss the materials and techniques used in the project, including the octagonal roofs and “wavy” walkways.

Bob tours the factory where the project house’s custom crown molding is cut to custom specifications, while, back at the site, carpenter Bob Ryley struggles to install the molding on uneven walls.

Bob and the contractor discuss the concrete walkway, with the contractor giving Bob tips on how to make concrete cure harder and have less cracks. Also discussed is the crushed, aggregate granite that will be added to the standard concrete.
