Looks like an index wheel being made. How is it going to be mounted?
I've become amazed with rose engines and ornamental turning so I'm making a wooden prototype based around the double bearing quill. Its going well so far. The indexing wheel and a couple more and the headstock portion will be done.
Once its satisfactory, I'll build another more accurate one. This one is close but not close enough but it's an excellent learning exercise.
