The form is Catalpa from a friends yard. I've never seen ring rot in a log before, but had to turn away most of the log to get back down into solid wood. The wood had to be soaked in 50/50 white glue and water mixture for 48 hours, let dry for a week or two then final turned. Don't remember the size as I gave it to the guy who I got the wood from, but not over 10" for the form. Holly is dyed black with Feibing Leather Dye and finish is WOP. Thanks for looking.
