Convenient, printable .PDF file
This printable reference chart will show you exactly how many turns and holes it takes to divide your workpiece just how you want. The sheet includes both 40:1 and 90:1 dividing head configurations and ranges from 2 to 100 divisions (although not all are possible with standard index circles)
Works with Ellis Dividing Head, and any 40:1 or 90:1
The reference chart is fully compatible with the Ellis Dividing Head, and includes "turn-and-hole" combinations for both 40:1 and 90:1 generic dividing heads
Wide range of applicable divisions: 2 to 100
Designed with versatility in mind, the charts include combinations from 2 divisions up to 100. Whether it's 6 bolts for a flange or 94 for a specialty application, the standard index circles have you covered. That said, certain combinations aren't possible with the standard Ellis plates and are shown with a "---" in the preview.
