This paper describes the use of collapsible molds for violins, violas, cellos and basses. Traditional instrument building has typically relied on solid inside molds. This presents some limitations in later stages of construction. The use of collapsible molds can simplify construction and give improved outline control. There is, of course, more than one way to do this. The authors present their choices and discuss the advantages and disadvantages of both collapsible molds and different methods of collapsible mold construction. Some practical advice is given from their experience. The paper is based on a presentation at the VSA convention in Baltimore in 2015.
