I started turning bowls a little over a year ago. Mostly I have turned smaller bowls (no larger than 6") but am beginning to turn larger bowls. My lathe will accommodate up to a 12" bowl.

Concerning scrapers . . .

1. There are round and half-round scrapers. It seems to me that the round scrapers would be the most useful for me, but, in fact, which makes the most sense for the bowls I will turn (and possibly some plates)?

2. Is there size that makes the most sense? I have seen 3/4", 1", and even 1 1/2".

3. There are also different thicknesses of scrapers. I have seen 1/4" and 3/8" (maybe there are others). Which is the most generally useful?

4. As for grinding angle, is there an angle which is best for smoothing the inside (and maybe outside of bowls)?

Maybe I have not supplied sufficient information. Keep in mind, I'm a beginner, especially when it comes to using scrapers.
