Chattering gouge problems

[John Keeton]

.....and very little pressure to hold it to the tool rest.

I think this is the key. When I first started turning, my tendency was to hold the tool to the wood. The wood moves, and thus the cut moves. That is when "the bounce" starts!

The wood is still going to move, and some bounce may be unavoidable. But, if the effort is directed toward keeping the contact edge of the tool in constant position as it moves around the curve of the piece, one is far more likely to get a smooth and concentric cut.
