turning a hf thats bigger than i normally do... I turn mostly mesquite, walnut, or elm... almost always end grain...
Piece of walnut I'm doing is about 15 inches deep....using a boring bar..... and i keep getting tear out, while using a scraper to clean up the bottom..
is it because i need a tool rest thats deep inside the hollow form? or a heavier boring bar? I'm using a steady rest, so thats not the reason...
so whats causing the vibrations?
