This is an Excel 2007 Workbook. This calculator is made to use in conjunction with the Globe Knot Cookbook. Through collaborative efforts and original calculations based on the Globe Knot Cookbook this calculator is made to help in producing the right core size based on 3 user inputs, Passes, Cord Size, & Facets.
What you do is pick out a globe knot from the cookbook and enter the values into the user input fields to yield the result of what size core you will need.
