The instructions also go into detail on how to make a ring mandrel.
These are one piece cores, meaning they do not separate. Rings are available in sizes from 5-13. Sizes 5-8 are only available in 6mm width, Sizes 9-13 are now available in 6mm or 8mm. Sorry, half sizes are not available.
Getting the right hole size for the ring cores is the most difficult part of making a ring since they don't exactly match any standard drill bit sizes The best way to make the core fit is to find the closest (smaller size) drill bit and widen the hole with a small skew chisel or scraper. Click HERE for instructions on how to make a special ring tool out of a regular wood chisel.

Bought these cores so my students in my wood shop could try making rings. Even grade 7 kids have the greatest success. Will be purchasing again.
