Jackman Segmented Ring Calculator
$0.00
Description
Excel document download to help you make segmented rings. The excel workbook contains 2 tabs:
- Calculation sheet – input the number of segments in your ring along with the ring diameter and the sheet will automatically calculate the angle of your cut, segment length (on the long side) and the total board length needed to make that ring.
- Printable sheet – includes common combinations of segment quantities and ring diameters to give you the length of segment in a printable form to hang up in your shop and use on the fly.





This is the first time I have turned a segmented bowl. With your segmented ring calculator I was able to get into segmented rings much easier and a lot more accurate.
easy to use.
