Do your know it probably would not hurt if you took a lesson in bowl turning down at the local Woodcraft or woodworkers guild before you try one yourself. It also seems that it is even more important that you should probably try a traditional bowl blank the first time or two.
I didn't but two broken chisels and a chewed up do it your self laminated bowl blank later, I now know those hard learned lessons. That and a big pile of wood chips is all I got out of it. But, I learned a lesson.
I guess that is how we all learn. We learn the hard way.
