I've turned about 10 or 20 bowls so far and am considering getting a chuck. So far, I've just used plates with a scrap piece of wood glued to the bottom of the bowl for finishing (see attached pic).
If I start using a chuck, do I always need to turn some sort of footing on the bowl? My process so far has used a small curve in to avoid wobbling, but no largely noticeable footing (see pic). I've also seen people selling bowls that do have a noticeable footing ... are these people all using faceplates?
Also, how do I "clean up" the footing when finishing the bowl? Do I need to reverse the bowl and use some sort of vacuum chuck?
