Well, custom made by me. I had this idea/drawing in my head for a while now. It was for a small ring mandrel I needed for my wooden rings. Well, I finally executed on it and turned it myself on my mini metal lathe. Worked out very well and I just wanted to share it with “the internet” – not sure if there is anybody there interested in such non-sense as my custom tool making, hehe. I might even make a video and show you why I needed it and show you how I use it.
