I had my Rockler class yesterday on Natural edge bowl turning. The instructor had a hunk of birch for me.
I can't say that I've been sucked into the "spinny vortex" yet but I did have a good time. This is just about my first attempt of turning anything since high school.
I finally understand now what the terms, chuck, jam chuck, cutting the dovetail, and super sharp tools mean.
It was fun and the bowl came out not too bad.
