Use of Cores in the Fabrication of Kirksite Stretch Forms and Other Large-Sized Kirksite Tools

摘要

Kirksite stretch forms have previously been made without the use of cores. Completed forms are heavy, difficult to handle and machine; material costs are high. A method of making cores for Kirksite stretch forms was developed. Cored forms were successfully fabricated and a substantial over-all cost reduction was effected. (Author)
