This is the second part of a three-part article on how to enlarge (also called pointing up) and alternatively, how to shrink the size of a casting without the use of laser scanning, CAD/CAM and computer operated CNC machinery. The procedures for both are much simpler than one would imagine and avoids the cost and the complexity of high-tech equipment. The first part of this article described the steps on enlarging a casting by enlarging the mold. Part two provides an alternate method of casting enlargement by actually enlarging the casting, rather than the mold as previously described, as the first part in the enlargement process.
