Hi all,

I'm new to turning (so that may be the problem here...). I've been
practicing on some mahogany I had around and have gotten fairly
successful. Well, I picked up a block of walnut and haven't been so
lucky with it. I'm trying to hollow out a shallow bowl and my
fingernail gouge quickly catches and throws the bowl off the lathe.
This is bad. I'd really appreciate some help here. Here's what I've
observed:

1. The stock is being held by a nova chuck expanded into a recess in
the bottom of the bowl. It's held pretty tightly.

2. My 1/2" fingernail gouge is brand new, sharpened with a tormek
jig. Sure seems sharp to me. I've never used it before, so technique
could easily be the problem.

3. The walnut is very dry.

4. If I use a scraper, I can be pretty successful with the hollowing.

5. If I use the gouge, it catches brutally and throws the bowl.

Any thoughts?

Many thanks,
Joe

Sounds like your not able to keep the bevel rubbing. That will let the
gouge catch. One method I was taught was to come from the middle of
the inside towards the outer edge with the hollow facing the area to
be cut, pulling the tip toward you.

I hope this is clear.
