A friend of mine gave me several large chunks of Poplar. I started making a vase out of one of them yesterday. All that I finished so far is the outside. I planned on doing the inside today. Now that I am thinking about the grain of the wood I am not sure that it will stay together. Has anyone else turned an HF out of Poplar? If so what should I be expecting. I am turning it at about 500 RPM and the width of it is about 10" across the top.
