Segmented woodturners who use the stack ring lamination technique, must precisely calculate the cutting angles used in the process. The rings, which will eventually be stacked and glued one atop the other, are cut as concentric circles from a flat piece of turning stock. In theory, any thickness and size of stock can be used. The method of cutting can vary, but the calculations involved are always the same.

You don’t need to be a mathematician to determine the correct angle — just some graph paper, a pen, and a ruler. A protractor comes in handy too. In this video segment, woodturner Mark Damron shows how to quickly and easily determine the correct angle for any project. You’ll learn how to balance ring thickness and board thickness with cutting angle options so that you can achieve your desired design. Don’t let the numbers scare you. I can assure you — Mark makes it easy. (6.5 Minute Video)

Very good. I will be looking for more information in the future. I would have liked to see how you cut the rings. Please let me know if you will be showing this in other videos. Thanks.
