It works well. Functionally, it’s pretty great.It comes with some extras, but not much of an explanation. Because it can mount parallel or perpendicular, it lacks a way to clamp it to the table for parallel use. I had to machine a toe clamp to hold the other end. Thankfully, I have a mill. But, it’d have been so much easier to include one since it’s necessary.Otherwise, the 90 turns for 360 (1 for 4), works out pretty well for any angle divisible by four - 72, 60, 120, etc. I had to machine a way to attach my lathe chuck. Spent a half hour making the little piece I pictured… worked well for not using the dividing plates.Solid. Fairly precise. Works. But you’re going to have to make things to use it.
