I use walnut oil on many of my bowls. I like it for finishing some of
my turnings. It is easy to apply, is food safe, and can be used and
handled right after application. I especially like it on some of the
darker woods. MIke Mahoney makes a good product. He has both pure
walnut oil and he also has a cream that is made of walnut oil and some
waxes. A couple of problems I find with walnut oil are that it can
take quite a while to fully cure and it can turn some light colored
woods too dark.
