Sure, Oland tools can take the place of bowl gouges easily. Lissie Oland
will happily rough and finish turn a 30" walnut bowl using only the 1/4"
Oland. See http://www.olandcraft.com/ for an example or two. Of course she
cores the thing with a chain saw which I am not about to do. I like the
Oland tools in sizes from 1/8" to 1/2". My lathe and my market tend to keep
me in the 14" range for a big bowl but bigger and smaller are no problem for
an Oland tool. These are cutting tools, not scrapers although a shear cut is
no problem.
