Abstract
A tool for reforming a core pattern. A method of reforming a core pattern comprises opening a core reformer tool. The core reformer tool has a first portion and a second portion facing the first portion. The first portion includes a concave member and a first adjustable pin. The second portion includes a convex member and a second adjustable pin. The method includes positioning the core pattern in the core reformer tool and closing the core reformer tool. The method comprises adjusting at least one of the first adjustable pin and the second adjustable pin to alter a surface of the core pattern. The method includes directing cooling air through the core reformer tool to solidify the core pattern and opening the core reformer tool to remove the core pattern.
