Turn your own wooden rings using these stainless steel bands. Click here for detailed instructions on how to turn your own rings, courtesy of Dave Mueller of



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.

    Possibility of slightly wider cores???

    Posted by Unknown on Mar 19th 2017

    Bought about 20 of your cores and they are amazingly simple to use and all the rings I have made have come out looking great. Is there any possibility that you may have some of the larger sizes (8-13) a bit wider in the future? Maybe 3/8". I am using 3 3/8" pieces glued together separated by a thin veneer so I can't use the cores for those rings.

    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.
