Don't toss it. Pieces like that are good candidates for jam/friction chucks of various sizes. I have a drawer full of 'em in various stages of "bowlness".
OK, I won't, but I AM going to rechuck it with the face plate (I used my pin jaws and it wobbled fairly frequently). Ash, rock hard despite the cracks.
One thing to keep in mind of you're using this later as a jam/friction chuck it you should plan on needing to re-true it each time you put it back on the lathe. Each time I use one of mine, it gets a little smaller as I true it up (and often change the shape to fit the piece I'm finishing the bottom on.). I wouldn't even bother putting in on a faceplate until you need it.
Yeah, pretty much my thought too, pin jaws will be for bird house ornaments...
Just fill those checks with espresso powder and CA...instant design opportunity!
