I have made some of the rings and bangles from Wildwood. The supporting videos found on the site suggest mounting the wood material, then turning the wood. You also cut right into the metal core, resulting in a smooth transition from core to wood. The CA is applied and finished to the desired appearance, coating all of it, wood and metal. After that, you carefully remove the CA from the metal part, and again carefully fine sand the metal only(stainless or titanium), bringing it up to a nice shine. It sounds difficult, but is not that hard to do after trying a few. The result is a nice finish product. I am in the process of making an inventory of these to sell along side my pen offerings. The ring shown here in the thread is nicely done.
