    Is there a recommended list of drill bit sizes for various ring sizes? Or a set of instructions for rings that will provide more information on what is needed to prepare the blank?

    Have you viewed the instructional video? Link below:
    https://www.youtube.com/watch?v=X8pwzD0jc4s&feature=youtu.be

    Simply measure the Outside Diameter of the ring core and choose a drill bit that is slightly smaller. Then "fine tune" the hole as shown in the video.

    Ring sizes run from 4 to 17 (that I know of)--in half sizes--each step is minuscule.
