When I first started machining 6 or 7 years ago, I bought a rotary table which came with a set of divider plates. I mounted a 3 jaw chuck on it, and have since built numerous spur gears and used it for putting a radius on the corner of plates, connecting rods, etcetera. It is a good rotary table, in the sense that it has two machined mounting faces, so it can be mounted with the center of the 3 jaw chuck mounted either vertically or horizontally. Now I am seeing posts on this forum which talk about dividing heads. I don't know much about dividing heads, and I would like to know where they would be used and what makes them in any way "better" or "worse" than the set-up that I have. Can someone enlighten me please.---Brian
