How did you do that? I assume you have some kind of jig attached to the tailstock?
I've been rather saddened lately. There used to be some WONDERFUL tools on the market to help do decorative turning like this. I think there were five or six different options for decorative woodworking jigs and systems on the market. I don't know if it was just the pandemic, or if maybe the creators of these tools just reached an age where continuing their businesses was not really viable (I know that Beall retired at the end of 2022...thankfully his patents were bought up by Lee and I think a UK company, and most are still being made, but...the Pen Wizard, as far as I know, has not been remanufactured yet....I felt lucky to grab one of the last before I think they were gone from the market, and its another one of those unique decorative turning tools!)
I really like this kind of decorative turning, though...and have been trying to figure out how to make something myself. I don't have the skills, particularly with metal working, to really create anything I think might actually work, and I also don't really have the knowledge that some of the guys who came up with the previous systems had from an engineering/design standpoint either... Anyway, its quite sad, the loss of skill, knowledge, and tooling in this area...
